Abstract: Process for the recovery of pure, water insoluble alpha , beta -ethylenically unsaturated carboxylic acid esters is carried out in a single step by means of an aqueous base. A process for the recovery of pure, water-insoluble esters of alpha , beta -ethylenically unsaturated carboxylic acids from a mixture containing unreacted carboxylic acids and/or an acid catalyst and optionally a polymerization inhibitor is claimed. The process comprises removal of the impurities in a single extraction step using an aqueous base and separation of the aqueous base and impurities.

Abstract: A process for the production of (meth)acrylate esters (I) by esterification of (meth)acrylic acid (II) with mono- or poly- hydric alcohols (III) is claimed. The reaction mixture, still containing (II) in amounts equivalent to an acid number of at least 5 mg KOH/g, is treated with amino compound(s) (IV) containing at least one prim., sec. or tert. amino group. Also claimed are: (1) esters (I) obtained by this process; and (2) radiation-curable materials (RCM) containing (I).
