Patent GB-824574-A (GB)
Title: Process for the fractionation of fatty acid mixtures
IPC: C11C1/00
Filed: 1957-06-27
Abstract: A mixture of fatty acids is separated into relatively saturated and unsaturated fractions by forming an aqueous solution, preferably of pH 7-8, containing the fatty acids at least in part in the form of their acid soaps, at a concentration of not more than 10%, the amount of electrolytes present being desirably less than 1%, and then ageing the solution, suitably for a period of at least 3 hours, at a temperature below 30 DEG  C., whereupon a solid fraction rich in saturated acids crystallizes and is recovered, leaving a fraction rich in unsaturated acids in solution in the mother liquor.  Fatty acid mixtures suitable for the process include those derived from palm, coconut, repeseed, cottonseed, linseed, peanut, soybean or fish oil, tallow or soapstock, in which last case any free oil present is first saponified before treatment.  The soap solutions are suitably formed at a temperature above the gelling point of the soaps and any suitable alkali may be used, for example sodium, potassium, or ammonium hydroxide or carbonate.  The acid soaps of general formula HX.MX, where X is a fatty acid radical and M is sodium, potassium or ammonium, are then formed by treating the solution with mineral acid, free fatty acid, for example from soapstock, or preferably, carbon dioxide until the required degree of acidification has been achieved. The mixture so obtained is then gradually cooled, suitably to a final temperature of 10 DEG  C., over a period of several hours and the solid fraction of acid soaps which separates, and which contains the relatively saturated fraction of acids, is separated from the mother liquor, preferably by filtration.  A suitable apparatus, employing carbon dioxide as the acidifying agent, is described.

Title: The manufacture of dyestuffs of the copper phthalocyanine type
Inventor: O'NEAL GRADY MALCOLM
IPC: C09B47/067
Filed: 1947-10-29
Abstract: Copper phthalocyanines are prepared by reacting in nitrobenzene saturated with ammonia gas four molecular proportions of a cyclic ortho-dinitrile other than phthalonitrile and a quantity of a reaction product of ammonia with solid hydrated or solid anhydrous cupric acetate to provide at least a corresponding atom equivalent of copper, at a temperature in the range from 100 DEG  C. to the reflux temperature at normal atmospheric pressure, and separating the resulting dyestuff from nitrobenzene.  The temperature is preferably above 115 DEG  C., and the reaction product may be formed in situ or in a separate step.  The o-dinitriles may be derived from mono- and poly-nuclear cyclic hydrocarbons and heterocyclic compounds such as naphthalene, anthraquinone, pyridine, quinoline.  In an example, nitrobenzene, 4-nitrophthalonitrile, and anhydrous cupric acetate are mixed and treated with anhydrous ammonia at room temperature rising to 40-50 DEG  C., to form the cupric acetate-ammonia complex, the temperature being then raised to 130-135 DEG  C. for three hours. Specification 599,247, [Group XXXVI], is referred to.
