摘要： Process for the recovery of carboxylic acid, in particular acetic acid containing carboxylic anhydride in particularacetic anhydride and other impurities, which comprises: (a) treating a fraction, in particular a fraction originating from a wood treatment process, containing carboxylic acid and impurities with a metal salt in the presence of water, (b) treating at least part of the fraction obtained from step (a) to remove metal salt and, (c) treating at least part of the fraction obtained from step (b) by distillation, stripping or membrane separation to recover at least a purified carboxylic acid fraction.

摘要： The invention concerns a process for the manufacture of an acylated polymer composition comprising amylose and/or amylopectin, comprising a pre-treatment step in the presence of an acid, and optionally one additive selected from the group of a hydroxycarboxylic acid and a salt in combination with a polycarboxylic acid. After pre-treatment, the polymer is acylated and, preferably, subjected to a post-treatment step with an acid. The products obtained are useful as additives in varnishes, lacquers, coatings, thickeners, adhesives or binders, and preferably inks.
