Title: Process for separation of chlorinated polymers from carbon tetrachloride by azeotropic distillation
IPC: C08C2/06
Filed: 1963-09-11
Abstract: Chlorinated polyvinyl chloride, polyethylene, polypropylene, polyisoprene and natural rubber substantially free from organic solvents, are isolated from mixtures in which the polymers are associated with carbon tetrachloride by a process in which methanol, ethanol, a propanol or tertiary butanol is added to the mixture as liquid and/or vapour, the carbon tetrachloride is removed as an azeotrope with the alcohol by fractional distillation, and any residual alcohol is subsequently removed from the polymer.

Title: Process for the manufacture of vinyl esters of carboxylic acids
IPC: C07C67/055
Filed: 1968-02-29
Abstract: Vinyl esters of carboxylic acids are prepared by a process which comprises passing ethylene, oxygen or gases containing oxygen, and carboxylic acids in the gaseous phase at an elevated temperature over a catalyst comprising a carrier, e.g. silicic acid, a salt of a noble metal of Group VIII of the Periodic Table, and also 0À01 to 200 grams, per litre of catalyst, of cadmium in the form of the cadmium salt of a carboxylic acid.
