Title: Improvements relating to the production of alkylamines
Filed: 1934-06-26
Abstract: Diamines of the formula (CH2)n(NRR<1>)2, where n is 7--13 inclusive and R and R1 are alkyl groups, which must not both be ethyl groups, are prepared from compounds of the formula (CH2)nX2, where X is halogen, by heating these with secondary amines of the formula NHRR<1>. In the examples (1) 1 : 10-di(di-n-amylamino)-decane is prepared from 1 : 10-dibromodecane or 1 : 10-dichlorodecane and di-n-amylamine; (2) 1 : 10-di(n-butyl-n-dodecylamino)-decane is prepared from 1 : 10-dibromodecane and n-butyl-n-dodecylamine; (3) 1 : 10-di(n-amyl-n-butylamino)-decane is prepared from 1 : 10-dibromodecane and n-amyl-n-butylamine; (4) 1 : 10-di(di-n-butylamino)-decane is prepared from 1 : 10-dibromodecane and di-n-butylamine; the neutral tartrate of this product is described.  The following compounds are obtainable in a similar manner:--1 : 7-di(di-n-butylamino)-heptane, 1 : 10-di(di-n-propylamino)-decane: 1 : 10 - di(diisoamylamino) - decane, 1 - 10-di-(di-n-hexylamino)-decane, 1 : 10 - di(di - n - heptylamino)-decane, 1 : 10 - di(ethyl - n -do-decylamino)-decane, 1 : 11 - di(di - n - amylamino)-undecane, 1 : 12 - di(di - n - butylamino)-dodecane, and 1 : 13-di(di-n-butylamino)-tridecane.  The products are useful as amoebicides.  Secondary amines of the formula given above are obtainable by hydrolysis of the corresponding N-substituted p-toluenesulphonamides.  Thus, n-butyl-n-dodecylamine may be prepared by treating the sodium salt of p-toluenesulphonamide with butyl toluenesulphonate to yield N-butyl-p-toluene sulphonamide, treating the sodium salt of this compound with dodecyl bromide to form N-butyl-N-dodecyl-p-toluenesulphonamide, and hydrolyzing the latter with sulphuric acid.  n-Amyl-n-butylamine is similarly obtainable.

Title: Manufacture of intermediates in the synthesis of adrenal cortical hormone
IPC: C07J41/00
Filed: 1947-07-16
Abstract: 3 - Acyloxy - 11 - keto - 20 - aminopregnanes are manufactured by heating 3-acyloxy-11-ketobionorcholamic acid azide in a dilute aqueous acid (organic or inorganic), treating the resulting solution of the salt of 3-acyloxy-11-keto-20-aminopregnane with an alkali in the presence of an organic solvent at a low temperature and isolating the liberated base from the solution.  The starting-material is obtained by treating 3-hydroxy-11-ketobisnorcholanic acid with an acylating agent (e.g. an organic acid, preferably an aliphatic carboxylic acid containing not more than 6 carbon atoms in the molecule, or the corresponding anhydride), treating the resulting 3-acyloxy compound with a reagent capable of converting a carboxylic acid to a carboxylic acid halide (e.g. a thionyl halide or a phosphorus tri- or penta-halide), and reacting the resulting acid halide with a metal azide (especially an alkali or alkaline-earth metal azide).  The 3-acyloxy-11-keto-20-aminopregnane may be further treated with alkali under saponification conditions to form the corresponding 3-hydroxy compound, and this or the 3-acyloxy compound may be acylated to give a 3-acyloxy-11-keto-20-acylaminopregnane, which may be partially hydrolysed to 3-hydroxy - 11 - keto - 20 - acylaminopregnane.  In an example: 3(a )-hydroxy-11-ketobisnorcholanic acid (obtained by saponifying methyl 3(a ) - acetoxy - 11 - ketobisnorcholanate with aqueous methanolic caustic potash and acidifying with dilute hydrochloric acid) is refluxed with glacial acetic acid (or acetic anhydride), the resulting 3(a )-acetoxy compound is warmed with thionyl chloride, the acid chloride is treated in acetone at 0 DEG  C. with an aqueous solution of sodium azide, the resulting azide is heated with dilute acetic acid, and 3(a )-acetoxy-11-keto-20-aminopregrane is liberated by the action of cold potassium hydroxide solution.  The product, or the corresponding 3-hydroxy compound, may be treated with acetic anhydride and pyridine to give 3(1)-acetoxy - 11 - keto - 20 - acetylaminopregnane, which on saponification with alkali yields 3(a ) - hydroxy - 11 - keto - 20 - acetylaminopregnane. Alternative acylating agents in the first step of the process are propionic, butyric or valeric acid or anhydride, caproic or capric acid, benzoic acid (or benzoyl chloride and pyridine), or toluic or phenylacetic acid.

Abstract: 147,633. Collin Akt.-Ges. zur Verwertung von Brennstoffen und Metallen, F. J. March 3, 1919, [Convention date]. Ammonium sulphate and chloride.-Hot distillation gas is treated in a cooler a with cooled ammoniacal liquor condensed during the cooling process, and is washed with a similar liquid in a washer b. The liquor and tar collect in a tank d in which the tar is separated, the liquor being forced through a cooler f and re-used in the cooler a and washer b, thus completing one circuit. A portion of the liquor is taken away and supplied to a still g, where it is treated without the addition of lime. The ammonia is either collected as a strong solution in water or led to a saturator h, from which the salt is carried by a siphon i to a trickling plane k and centrifugal separator l. The water from the still g containing the fixed ammonia is supplied by a pump m to a tower n where it is cooled by evaporation, thence it is pumped by a pump o either to the washer band thence back to the still g, thus completing a second circuit, or to the cooler f to act as cooling- agent and back to the cooler n, thus completing a third circuit and increasing the percentage of fixed ammonia in the water. A portion is from time to time taken away and, after passing through a regenerative cooler p on the still g, is conducted to the saturator h, the acid in which takes up the ammonia; the water is evaporated and passes out with the sulphuretted hydrogen and carbon dioxide. It is advantageous to use in the upper part of the washer b the fixed ammoniacal solution, and in the lower part the liquor from the cooler f also. Ammonium chloride can be obtained in marketable form from the water containing fixed ammonia, by evaporation.

Title: Laser relaxation oscillators
IPC: H04B10/50
Filed: 1971-06-09
Abstract: 1321389 Lasers WESTERN ELECTRIC CO Inc 9 June 1971 [10 June 1970] 19690/71 Heading H1C In a self pulsing solid state laser of the relaxation oscillator type in which the repetition frequency of the output pulses is determined by the intensity of optical pumping; the pulse frequency is stabilized by modulating the laser pumping energy so that a corresponding modulation appears in the output pulse train, and comparing the phase of the output modulation with that of the source modulating the laser pumping energy, a difference in phase causing a change in the pumping energy intensity and consequential change in the output pulse frequency such as to reduce the phase difference. As shown in Fig. 1, a neodymium-doped YAG crystal or glass laser active medium 13 is located in a resonator formed by mirrors 15, 16, the active medium being pumped by a main tungsten-iodine or krypton lamp 17 and by an auxiliary modulating pump lamp 19 which may consist of a GaAs light emitting or laser diode. The output of the auxiliary pump lamp is focused by lenses 15, 20, and modulation of the same frequency as the laser output pulses, e.g. 150 kc/s., is produced by the amplified output of an oscillator 21. A proportion of the laser output is extracted by a beam splitter 23 and is applied through a light rejecting filter 24 to a photodetector 25 which may be a photodiode. The output of the photodetector represents the phase and amplitude of the laser output pulses and is compared in a phase sensor 27 with the phase-shifted output of the oscillator. Any difference between the two phases detected by the phase sensor causes adjustment of the pumping energy from the main lamp 17 through its controlled D.C. power supply 18, the adjustment being such that the laser output pulses are frequency regulated. In an alternative arrangement avoiding the effect of "hole burning", Fig. 4, the laser operates in a single mode and emission frequency by the use of two electrooptic cells 53, 54 within the resonator, the cells being energized by A.C. from a centre-tapped transformer 60 in opposite respects so that an optical dithering effect equivalent to vibrating the laser active medium along the resonator axis is obtained. In a modification applicable to either embodiment, the auxiliary modulating pump lamp is omitted and the main pump lamp directly modulated over the path shown in broken lines.
