Patent GB-536338-A (GB)
Title: Improvements in and relating to compositions of fatty oils and synthetic resins
IPC: C08G8/00
Filed: 1939-11-09
Abstract: 536,338. Synthetic resin compositions. BAKELITE, Ltd. Nov. 9, 1939, No. 29776. Convention date, Nov. 16, 1938. [Class 2 (iii)] Resinous compositions are prepared by blending a heat-hardenable phenolic synthetic resin with the reaction product of a phenol and a fatty oil or fatty acid produced in the presence of a condensing agent. Suitable phenols include phenol, cresols, xylenols or alkyl or aryl substituted phenols ; suitable fatty oils or corresponding fatty acids include tung, linseed, rape seed oiticica, perilla, fish oils, dehydroxylated castor oil including heated or blown oils; suitable condensing agents include phosphoric, boric, hydrochloric, oxalic, acetic and salicylic acids, aluminium and sulphur chlorides, aluminium, magnesium oxide, zinc oxide, lead oxide, cadmium oxide, sodium acetate, sodium borate or zinc stearate. Suitable phenolic resins include those prepared by condensing alkyl- or aryl-substituted phenols (cresols, xylenols, amylphenols, butylphenols and phenylphenols) with formaldehyde in the presence of an alkaline catalyst such as ammonia or sodium hydroxide. In examples, a reaction product of phenol or commercial cresol and tung oil produced in the presence of phosphoric acid or of phenol and tung oil produced in the presence of boric acid is blended with a heat-hardenable resin such as that produced by condensing p-phenylphenol with formaloehyde in the presence of ammonia, the composition being diluted, if necessary, to the desired viscosity by means of toluene or xylene.

Title: Purification of crude aliphatic alcohols by distillation
IPC: C07C29/74
Filed: 1948-11-16
Abstract: <PICT:0663561/III/1> A crude water-soluble C3 to C5 aliphatic alcohol obtained synthetically from a mono-olefin, e.g. by hydration or by reaction with carbon monoxide and hydrogen, is purified and rendered substantially non-odorous, by feeding the crude alcohol into the side of a fractionating column which is supplied with water, at a point above the crude alcohol inlet, so as to maintain at least 70 mol. per cent water in the internal reflux of the rectification zone, the proportion of water being sufficient to increase the relative volatility of the "polymer oils" contained in the crude alcohol, and withdrawing overhead and/or as a side stream the major proportion of the "polymer oils" and other impurities while a dilute aqueous solution of the purified alcohol is withdrawn from the base of the column.  The "polymer oils" comprise hydrocarbons resulting from polymerization of the olefine during the synthesis of the alcohol, together with ketones and higher alcohols.  Crude isopropanol obtained by hydration of propylene using sulphuric acid as catalyst, containing water (33 per cent), isopropyl ether (4 per cent) and "propyl oil" (0,8 per cent), was fed through line 1 at 518 gallons per hour and at a temperature of 79 DEG C. on to the 23rd plate of 30-plate column 2. The "propyl oil" comprised sec. heptanol, sec. octanol, hydrocarbons boiling within the range 60-300 DEG , and ethers boiling above 100 DEG C.  Water (790 g.p.h.) at 91 DEG C. was fed on to the 29th plate of the column through line 3.  Open steam was fed to the reboiler 9 of the column.  The isopropyl ether and about 90 per cent of the "propyl oil," were taken off overhead, and withdrawn from the system through line 7 (there was no external reflux). The bottoms (1460 g.p.h.) from column 2 contained 19,4 per cent isopropanol, 80,5 per cent water, and 0,02 per cent "propyl oil."  These bottoms were passed through line 8 to concentration column 12 from which purified aqueous isopropanol (91,4 per cent) was withdrawn through line 17.  A side stream comprising aqueous isopropanol contaminated with "propyl oil," was withdrawn from column 12 through line 18, while aqueous isopropanol contaminated with acetone, was withdrawn overhead. The bottoms from column 12 consisted of water, part of which was returned to column 2 through lines 19 and 3.  In a modification, a sidestream containing "propyl oil" may be withdrawn from column 1 through line 24.  This sidestream is allowed to separate into two layers in decanter 25; the oil layer is discarded, and the aqueous (i.e. the lower) layer is returned to the column through line 26.  The purification of sec. butanol, and of a mixture of sec. and tertiary amyl alcohols with sec. butanol, is also referred to.  In the case of butanol and amyl alcohol, the solubility in water may be increased by raising the temperature, or by adding acetone.  The water used for reflux may contain sodium acetate, sulphurate acid or sodium hydroxide. Specification 598,346 is referred to.

Abstract: 1474833 Resonant cavities ATOMIC ENERGY OF CANADA Ltd 17 July 1975 [18 Nov 1974] 30027/75 Heading H1W Apparatus for tracking the resonant frequency of a high power liquid cooled cavity structure includes first and second reference cavities turned to frequencies below and above the said resonant frequency, respectively, and provided with means for maintaining a first wall portion of each of the reference cavities at a first temperature, and a second wall portion of each of the cavities at a second temperature. As described, each reference cavity is provided with two independent liquid heat-exchange conduits e.g. in Fig. 2 the cavity 13, having input port 18, an opening 19 for a measurement probe, and a fine tuning screw 17, has a fluid conduit 20 for wall 11, and a conduit 21, 22, 23 for wall 15. In the tracking apparatus e.g. for monitoring the source exciting the high power cavity structure of a particle accelerator and maintaining it at the resonant frequency-a small fraction of the source output is fed equally to the two reference cavities. Any difference in the power levels in the reference cavities is employed to adjust the source frequency, approximate compensation for temperature change of the high power cavity structure being obtained by feeding the coolant of the latter through one conduit of the two reference cavities before, and through the other conduit of two reference cavities after, its passage through the cooling system of the high power cavity structure. Fig. 1 shows a structurally combined pair of cavities 2 and 21 having fluid conduits 7, 7<SP>1</SP> and 6, 6<SP>1</SP>.

Title: Manufacture of 1-phenyl-2-amino-propan-1-ols hydroxylated in the phenyl nucleus
Filed: 1932-10-31
Abstract: 1 - Hydroxyphenyl - 2 - aminopropanols - 1 are prepared by halogenating a mono- or dibenzyloxypropiophenone, treating the product with dibenzylamine, and hydrogenating the resulting dibenzylaminoketone ether in the presence of a noble metal catalyst. The hydrogenation not only reduces the ketone to the alcohol but also eliminates the benzyl substituents.  The halogenation may be effected in the presence of an acid-binding agent, e.g. a metal carbonate such as calcium carbonate, sodium bicarbonate or barium carbonate, or a metal oxide such as magnesium oxide or zinc oxide.  The catalyst, e.g. platinum or palladium, may be used in the finely-divided state or as the oxide.  The products are useful therapeutically.  According to the examples: (1) 3 : 4-dibenzyloxypropiophenone is brominated, the bromopropiophenone treated with dibenzylamine, and the resulting 3 : 4-dibenzyloxy-dibenzylamino-propiophenone then treated in the form of its hydrochloride in alcohol solution with hydrogen in the presence of palladium black, yielding 3 : 4-dihydroxyphenylaminopropanol; (2) p-hydroxyphenylaminopropanol is obtained by chlorinating p-benzyloxypropiophenone, reacting the product with dibenzylamine and then hydrogenating as above with a palladium black catalyst; m-hydroxyphenylaminopropanol is similarly prepared via the bromo compound.  Specification 367,951 is referred to.
