Title: Process for the manufacture of gold compounds of degradation products of keratin
IPC: A61K38/01
Filed: 1930-06-18
Abstract: The albumose-like degradation products of keratin containing a sulphydryl group, obtainable according to the process of Specification 345,630, are reacted with a gold salt solution until the red colouration resulting from the addition of the gold salt just still disappears; or the addition may be stopped at an earlier stage. In an example, a degradation product of wool is mixed with an aqueous gold chloride solution; after neutralizing with caustic soda, the albumose-gold compound is precipitated with alcohol.  According to modifications of the process, the syrup resulting from the degradation may be directly neutralized and gold chloride solution then added, or an alcoholic solution of the above-mentioned syrup may be reacted with an alcoholic gold chloride solution, and the product precipitated by neutralization with alcoholic caustic soda.

Patent GB-790564-A (GB)
Title: Improvements in or relating to the fractionation of phenolic and naphthalenic oils
Filed: 1955-06-28
Abstract: Hydrocarbons are separated from phenols as present in phenolic and naphthalenic oils by adding water and a water-entrainer, e.g. the monoethyl ether of ethylene glycol, and then distilling the mixture in a fractionating column; the entrainer is chosen so that its water azeotrope forms a "buffer" (i.e. boils between) the hydrocarbon/water and the phenol/water azeotropes, whereby the hydrocarbon/water azeotropes are obtained, together with bases (if any), as the distillate leaving the phenols in the still.  In an example, phenolic oil (50 litres) having a B.R. of 140-225 DEG  C. and containing 70 per cent neutral oil, 28 per cent phenol and 1.8 per cent bases, is mixed with water (20 litres) and the monoethyl ether of ethylene glycol (15 litres).  The mixture is heated in a boiler, and the vapours are passed through a 50-tray column.  The hydrocarbon/water azeotropes are distilled off, with the bases, at a reflux ratio of 1 : 12 while the head-temperature rises to 98.8 DEG  C.  Xylene, styrene, cumene, ethylbenzene, coumarone, naphthalene and methyl naphthalene distil over successively; and the pyridine, picolines, lutidines, collidine and quinoline pass over successively together with the heavier hydrocarbons.  The glycol-ether and water azeotrope (99.3 DEG  C.) is then distilled off, followed by excess glycol-ether, so as to leave only the pure phenols in the boiler.

Abstract: 531,195. Synthetic rubber. DU PONT DE NEMOURS, E. I. June 29, 1939, No. 19000. Convention date, June 29, 1938. [Class 2 (iii)] A latex of a polymerized halogen-diolefine is stabilized against coagulation by electrolytes and finely-divided solids by adding to the dispersion of the polymer (which contains another emulsifying agent but must be free from betaines) a soluble betaine containing a long hydrocarbon chain of more than 12 carbon atoms attached to the nitrogen or carbon atom and in which the number of carbon atoms between the nitrogen and the acid-forming group if less than 5. Suitable betaines are N - stearyl - betaine, N - ocenyl - betaine, C - cetyl - betaine, C - cetyl di(oxyethyl) betaine and the quaternary salt C 16  H 33  (CH 3 ) 2 - N(Br) - CH 2  - CHOH - SO 2 ONa. The betaine is preferably added immediately before the electrolyte or finely divided solid. In an example, 2-chlorbutadiene 1-3 (free from monovinyl and divinyl acetylene, acetaldehyde, methyl-vinyl ketone and 1-3 dichlorbutene-2) containing dissolved sulphur and cyclohexanol is emulsified with aqueous sodium salt of sulphuric esters of alcohols derived from coconut oil acids and when polymerization is complete there are added ammonia, phenyl-α- naphthylamine and a solution of the sodium salt of an acid obtained by condensing naphthalene sulphonic acids with formaldehyde (described in U.S.A. Specification 1,191,480). C-cetyl-betaine is then added. The invention is advantageous when a neoprene latex has an addition of a soluble fluoride to prevent che deterioration of cellulose fabrics treated with the latex. Specifications 497,638, 523,208 and 529,839 are referred to. The Specification as open to inspection under Sect. 91 states that the betaine may be added to the dispersing agent or to the dispersion of the chlorbutadiene before or during the polymerization. This subject-matter does not appear in the Specification as accepted.
