Authors: Yamaguchi Yohei , Takebe Toshimasa 
Published: July 2006

Abstract
(1) It was found that the vapour pressures of decomposition of diaspore could be calculated by the following equation in the range from 400° to 500°. Logπ=14.820–9255.1/T.
(2) In the case of bauxite, the curve of decomposition pressure was found to be consisted of two parts. The first part can be expressed by the equation logπ=6.5277–2206.5/T, in the range from 200° to 340°, and the second roughly by logπ=5.2566–1780/T in the range from 350° to 450°.
(3) The heats of decomposition of diaspore and bauxite were calculated by the integrated equation of Clapeyron and Clausius.
(4) The specific heat of diaspore was determined by the calorimetric investigation and found to be c=0.2085+0.000127 t.

ON THE ACTION OF PHOSPHATE UPON HEXOSES. I. THE FORMATION OF ACETOL FROM GLUCOSE IN ACIDIC SOLUTION OF POTASSIUM PHOSPHATE
Authors: Nodzu Ryuzaburo 
Published: July 2006

Abstract
On steam distillation of a mixture of glucose and about 40% potassium phosphate solution of pH from 7.0 to 5.0, an appreciable quantity (4–5% of glucose used) of acetol and a little quantity of diacetyl- and methylglyoxal are found in the distillate. The more concentrated and the nearer to neutrality the phosphate solution is, the more favourable for the formation of acetol.
ON A NEW HYDROCARBON IN BASKING SHARK LIVER OIL
Authors: Tsujimoto Mitsumaru 
Published: July 2006

Abstract
Although small in proportion, a new octadecylene, C18H36, has been found to occur, together with pristane, in basking shark liver oil. In far smaller proportions, it probably occurs in many other, squalene-containing shark liver oils in association with pristane. The author has proposed the name “Zamene” for this new hydrocarbon.
ON THE FATTY ACIDS OF JAPAN WAX.
Authors: Tsujimoto Mitsumaru 
Published: July 2006

Abstract
The component fatty acids of a specimen of unbleached Japan wax, which contains no kernel oil, have been examined.
In agreement with the description in fat literature, palmitic acid is, of course, the main component. Myristic acid and the lower homologues appear not to be present; volatile lower acids stated to occur in Japan wax by old investigators are undoubtedly decomposition products formed by bleaching process. On the other hand, stearic and arachidic acids occur in appreciable proportions. The unsaturated acids consist mostly of oleic acid. A small proportion of linolic acid is present. Hexadecenoic and linolenic acids are probably not present.
It is difficult to mention the quantitative proportion of the individual acids, but rough approximation would be as follows: Palmitic acid 77%, stearic and arachidic acids 5%, oleic acid 12%, linolic acid small amount (less than 1%), dibasic acids 6%.
The above proportion of stearic and arachidic acids would be rather high; in their relative amounts the former seems to predominate.
It is interesting to observe that whereas myristic acid can not be detected in Japan wax obtained from Rhus succedanea, it occurs abundantly in the wax of “Tsutaurushi”, Rhus toxicodendron, var. vulgaris, a viny shrub belonging to the same genus Rhus.
The free acids in Japan wax have nearly the same composition as the mixed acids of the wax, but oleic acid is present in a far larger proportion.
THE HIGHLY UNSATURATED ACIDS IN SARDINE OIL. III. THE ISOLATION AND CONSTITUTION OF MOROCTIC ACID C8H28O2
Authors: Toyama Yoshiyuki , Tsuchiya Tomotaro 
Published: July 2006

Abstract
Moroctic acid C18H28O2 has been isolated from a large quantity of Japanese sardine oil. For the determination of its constitution, methyl moroctate was subjected to ozonolysis. Among the products of ozonolysis, propionic acid, propyl aldehyde, succinic acid, succinic semi-aldehyde, methyl hydrogen succinate, methyl ester of succinic semi-aldehyde, carbon dioxide, acetic acid and acetaldehyde were found. Three last named compounds are considered to be formed by the secondary decomposition of malonic acid and the corresponding aldehyde which are derived from the =CH·CH2·CH= group. The presence of malonic acid, though in a small quantity, in the products of ozonolysis was also indicated. In the next place, tetrathiocyano-derivative was prepared from methyl moroctate, and it was subjected to ozonolysis. Among the products of ozonolysis, propionic acid, propyl aldehyde, carbon dioxide, acetic acid, acetaldehyde and an oily thiocyano-compound were recognised. The oily thiocyano-compound yielded, on elimination of thiocyanogen followed by hydrolysis, a decadiene-dicarboxylic acid (Δ3:4, 7:8-decadiene-1,10-dicarboxylic acid). Hence, the constitution of moroctic acid is established as Δ4:5, 8:9, 12:13, 15:16-octadecatetraenoic acid which is expressed by the following formula. CH_3·CH_2·CH=CH·CH_2·CH=CH·(CH_2)_2·CH=CH·(CH_2)_2·CH=CH·(CH_2)_2·COOH

Published: July 2006

Abstract
Highly unsaturated C20-acids have been separated from sardine oil and they were further separated into the portions of different degrees of unsaturation with the results that an eicosatetraenoic acid C20H32O2 was isolated and also the presence of an eicosapentenoic acid C20H30O2 was proved by separating a fraction, in which this acid is concentrated.
THE HIGHLY UNSATURATED ACIDS IN SARDINE OIL. V. THE CONSTITUTION OF EICOSATETRAENOIC ACID C20H32O2
Authors: Toyama Yoshiyuki , Tsuchiya Tomotaro 
Published: July 2006

Abstract
The eicosatetraenoic acid separated from sardine oil was converted into the amyl ester, and the latter was subjected to ozonolysis. Among the products of ozonolysis were found: butyric acid, butyric aldehyde, succinic acid and amyl hydrogen succinate. The presence of succinic semi-aldehyde, succinic aldehyde and amyl ester of succinic semi-aldehyde was also indicated. Accordingly the constitution of the eicosatetraenoic acid is shown to be Δ4:5, 8:9, 12:13, 16:17-eicosatetraenoic acid as expressed by the following formula: CH_3·(CH_2)_2·CH=CH·(CH_2)_2·CH=CH·(CH_2)_2·CH=CH·(CH_2)_2·CH=CH·(CH_2)_2·COOH.
THE HIGHLY UNSATURATED ACIDS IN SARDINE OIL. VI.THE CONSTITUTION OF EICOSAPENTENOIC ACIDS C20H30O2
Authors: Toyama Yoshiyuki , Tsuchiya Tomotaro 
Published: July 2006

Abstract
A concentrated fraction of eicosapentenoic acid containing an appreciable amount of eicosatetraenoic acid was converted into amyl ester and the latter was subjected to ozonolysis. Among the products of ozonolysis were found: succinic acid, amyl hydrogen succinate, amyl ester of succinic semi-aldehyde, carbon dioxide, acetic acid, acetaldehyde and a higher aldehyde (probably butyric aldehyde). The yield of these compounds and also the constitution of eicosatetraenoic acid (Δ4:5, 8:9, 12:13, 16:17) being taken into consideration, it was concluded that the eicosapentenoic acid had the following groups: =CH·CH2·CH=, =CH·(CH2)2·CH= and =CH·(CH2)2·COOH, of which it contained more than one of the group =CH·CH2·CH=. As the group at the CH3-side was left undetermined in these experiments, the constitution of the eicosapentenoic acid was not established with certainty. If, however, it is assumed that there are ethylenic linkings in 4:5-, 8:9- and 12:13-positions like in the eicosatetraenoic acid, the constitution must be Δ4:5, 8:9, 12:13, 15:6, 18:19-eicosapentenoic acid as expressed by the following formula: CH_3·CH=CH·CH_2·CH=CH·CH_2·CH=CH·(CH_2)_2·CH=CH·(CH_2)_2·CH=CH·(CH_2)_2·COOH.

Authors: Harada Taichi 
Published: July 2006

Abstract
(1) The glucose tolerance on albino-rabbits was studied.
(2) The influence of calcium upon the activity of adrenalin on the blood sugar in the rabbit was experimented. It gave little change.
(3) An interesting relation between calcium and the carbohydrate metabolism of the body was observed: that is, calcium prevents considerably the elevation in both hyperglycemia and glycosuria which would occur when glucose alone or glucose-adrenalin without calcium was administered.
THE HIGHLY UNSATURATED ACIDS IN SARDINE OIL. IX. THE CONSTITUTION OF DOCOSAHEXENOIC ACID C22H32O2
Authors: Toyama Yoshiyuki , Tsuchiya Tomotaro 
Published: July 2006

Abstract
1.A concentrated fraction of docosahexenoic acid was converted into the amyl ester, and the latter was subjected to ozonolysis. Among the products of ozonolysis were found: acetaldehyde, acetic acid, carbon dioxide, succinic acid and amyl hydrogen succinate. The presence of the aldehydes corresponding to succinic acid and amyl hydrogen succinate was also indicated. Of these compounds, carbon dioxide together with acetaldehyde and acetic acid is attributable to the secondary decomposition of the products derived from the group =CH·CH2·CH=. The yield of carbon dioxide indicated the presence of at least three of the group =CH·CH2·CH= in amyl docosahexenoate. Consequently docosahexenoic acid has the following groups: =CH·CH2·CH=, =CH·(CH2)2·CH=, and =CH·(CH2)2·COOH, of which it has at least three of the group =CH·CH2·CH=. The yield of C4-compounds (succinic acid and the corresponding aldehyde) obtained by the ozonolysis gave an indication of the presence of more than one of the group =CH·(CH2)2·CH= in docosahexenoic acid.
2. Although the group attached to the CH3-side and the respective positions of the groups CH·CH2·CH= and =CH·(CH2)2·CH= were left undetermined in these experiments, the most probable structure of docosahexenoic acid was derived from the results obtained above.
THE HIGHLY UNSATURATED ACIDS IN SARDINE OIL. XL THE CONSTITUTION OF NISINIC ACID C24H36O2 IN SARDINE OIL
Authors: Toyama Yoshiyuki , Tsuchiya Tomotaro 
Published: July 2006

Abstract
Nisinic acid C24H36O2 has been separated from sardine oil, and its amyl ester subjected to ozonolysis. Among the products of ozonolysis were found: propyl aldehyde, propionic acid, asetaldehyde, acetic acid, carbon dioxide, succinic acid and amyl hydrogen succinate. Of these compounds propyl aldehyde and propionic acid are derived from the group CH3·CH2·CH=, whilst acetaldehyde and acetic acid together with carbon dioxide are attributable to the secondary decomposition of malonic acid and the corresponding aldehyde which are derived from the group =CH·CH2·CH=. The yield of carbon dioxide indicated the presence of more than two of the group =CH·CH2·CH=. Succinic acid and amyl hydrogen succinate are derived from the groups =CH·(CH2)2·CH= and =CH·(CH2)2·COOC5H11 respectively. Accordingly, nisinic acid was found to be composed of the following groups: CH3·CH2·CH=, CH·CH2·CH=(three), =CH·(CH2)2·CH= (two), and =CH·(CH2)2·CH= were not determined in these experiments. If, however, it is assumed that three of the ethylenic linkings in nisinac acid lie at 4:5-, 8:9- and 12:13-positions as is the case with previously studied moroctic, eicosatetraenoic and clutanodonic acids,the constipution of nisinic acid is expressed by the following formula:
CH3·CH2·CH=CH·CH2·CH=CH·CH2·CH=CH·CH2·CH=CH·(CH2)2·CH=CH·(CH2)2·CH=CH·(CH2)2·COOH
TETRADECENOIC AND DODECENOIC ACIDS IN SPERM OIL. I. TETRADECENOIC AND DODECENOIC ACIDS IN SPERM BLUBBER OIL
Authors: Toyama Yoshiyuki , Tsuchiya Tomotaro 
Published: July 2006

Abstract
Tetradecenoic acid C14H26O2 and dodecenoic acid C12H22O2 have been separated from sperm blubber oil. They are converted into dihydroxymyristic acid C14H28O4 and dihydroxylauric acid C12H24O4 respectively, and the methyl esters of these hydroxy-derivatives are subjected to the permanganate oxidation in acetone. From the results of an examination of the oxidation products, the following constitutions have been established:
Tetradecenoic acid CH3·(CH2)7·CH=CH·(CH2)3·COOH,
Dodecenoic acid CH3·(CH2)5·CH=CH·(CH2)3·COOH.
It is thus seen that tetradecenoic acid in sperm blubber oil is identical with physeteric acid (Δ5:6-tetradecenoic acid) in sperm head oil, whilst dodecenoic acid in sperm blubber oil, to which the name denticetic acid is assigned, is Δ5:6-acid and is an isomer of linderic acid (Δ4:5-dodecenoic acid) in the seed oil of Lindera obtusiloba.
ON THE OCCURRENCE OF NEW HIGHLY UNSATURATED FATTY ACIDS, C26H40O2 AND C26H42O2, IN TUNNY OIL

Published: July 2006

Abstract
The mixed liquid acids obtained from the sample oil by cooling were converted into methyl esters which were fractionally distilled under a diminished pressure of 4 mm. From the highest boiling fraction, the authors separated a new highly unsaturated acid C26H40O2((Remark: Graphics omitted.)6) and also detected the occurrence of another new acid C26H42O2 ((Remark: Graphics omitted.)5) besides scoliodonic acid (C24H33O), nisinic acid (C24H36O2) and clupanodonic acid (C22H34O2). The present authors propose the names “thynnic acid” for the acid C26H40O2 and “shibic acid” for the acid C26H42O2.

STUDIES ON THE CONSTITUTION OF SHONANIC ACID, ONE OF THE TWO CHARACTERISTIC VOLATILE ACIDS FROM THE WOOD OF LIBOCEDRUS FORMOSANA, FLORIN. I. THE ISOLATION OF SHONANIC ACID AND ITS GENERAL PROPERTIES
Authors: Ichikawa Nobutoshi 
Published: July 2006

Abstract
(1) The existence of an unknown acid in the volatile part from the wood of Libocedrus formosana, Florin, or “Shônan-Boku” is reported.
(2) Shonanic acid is an unsaturated monobasic acid with a monocyclic structure of the formula C10H14O2, melting at 40–41°. Its amide melts at 116-117° and the anilide at 111-112°.
(3) Shonanic acid can be converted into tetrahydroshonanic acid by absorption of four atoms of hydrogen when reduced catalytically, while it absorbs only two atoms of bromine, and when reduced with sodium and ethyl alcohol an unsaturated acid, viz. dihydroshonanic acid (C10H16O2), is obtained. These experimental facts together with the fact that the molecular refraction of shonanic acid exhibits an eminent exaltation lead to the conclusion that conjugated double bonds exist in its molecule.
(4) Though tetrahydroshonanic amide melts at 144°, it was proved that the acid is quite different from dihydro-a-campholenic acid (C10H18O2, amide m.p. 144°).
(5) Shonanic acid isomerizes to isoshonanic acid by the action of hot strong alkali solution. Iso-acid melts at 45° and gives an amide melting at 107–108°.
(6) The isomerisation of shonanic acid to isoshonanic acid is accompanied by the elevation of the boiling point to the extent of 13°C. This phenomenon may probably be due to the migration of semicyclic double bond into the ring system of the acid, which must be ascertained by further investigations.
Studies on the Flow of Gaseous Mixtures through Capillaries. III. The Flow of Gaseous Mixtures at Medium Pressures
Authors: Adzumi Hiroshi 
Published: July 2006

Abstract
(1) The quantities of seven following simple gases and six gaseous mixtures flowing through the capillary have been measured at the pressures between 4 and 0.01mm.
&H_2,C_2H_2,C_3H_6,H_2∼C_3H_6;
&C_6H_6,CCl_4,CHCl_3,(C_2H_5)_2O,C_6H_6∼CCl_4,CCl_4∼CHCl_3,
&(C_2H_5)_2O∼CHCl_3.
(2) The quantities of flow, K, is a function of the mean pressure, p, and the K−p curve passes through a minimum point. The occurrence of a minimum point of mixtures is more remarkable than in the case cf simple gases.
(3) The quantities of flow of simple gases are satisfactorily expressed by
K=ap+γb,
where γ is a coefficient which becomes a constant at higher pressures (=0.9) or at very low pressures (=1.0), and varies from 0.9 to 1.0 at the intermediate conditions.
(4) The quantities of flow of mixtures are also expressed by a formula analogous to that of simple gases. The values of γ′ at higher pressures of the mixtures are constant for varying compositions of the same combination of components, but different from those for different combinations and simple gases. These values are also considered to depend on the chemical configurations of two components.
(5) The viscosities of the following mixtures have been calculated from the quantities of flow.
C_6H_6CCl_4, CCl_4∼CHCl_3,  (C_2H_5)_2O∼CHCl_3.
The mixture CCl4∼CHCl3 shows a maximum at about 50% of CHCl3 and the viscosity curves of the other two are nearly straight.
Effect of Water on the Potential of the Glass Electrode
Authors: Yoshimura Hisato 
Published: July 2006

Abstract
(1) When one surface of the membrane of a glass electrode is dried, the asymmetry potential is raised on that side against the other side, and the hydrogen electrode function is decreased. This membrane being kept submerged in water, the reverse effect is observed. These facts can be explained qualitatively by any of the latest theories concerning the glass electrode.
(2) The significance of preserving the glass electrode in water after its preparation, which is a generally accepted procedure in the use of the glass electrode, can be stated as follows: (i) It makes the hydrogen electrode function approach Nernst’s theoretical value, probably decreasing the cation effect on the potential of the glass electrode, (ii) it decreases the asymmetry potential, equalizing the electromotive nature of both the inner and outer surfaces of the electrode membrane, and (iii) it facilitates the equilibration of the potential after the electrode is mounted in a solution for test.

A Theory of Surface Tension of Ternary Solutions
Authors: Ariyama Kyozo 
Published: July 2006

Abstract
The theories of surface tension of Debye-Hückel electrolyte can be divided into two main groups; one which is based on the assumption of the existence of the ‘image force’ near the boundary between water and air, and the other based on the calculation of surface free energy caused by the electrostatic force of ions. On the basis of experimental evidence on the surface tension of ternary solution, the theories of former category are shown to be unacceptable. Theories of Oka and also of Ariyama which belong to the latter category are applied to explain the surface tension of ternary solutions. Agreement with experiment is satisfactory.
