    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).

    Abstract: PCT No. PCT/EP95/04408 Sec. 371 Date May 12, 1997 Sec. 102(e) Date May 12, 1997 PCT Filed Nov. 9, 1995 PCT Pub. No. WO96/15097 PCT Pub. Date May 23, 1996A process is disclosed for preparing amines by hydrogenating compounds with at least 3 cyano groups prepared by adding acrylonitrile to ammonia or primary amines at temperatures from 80 DEG to 200 DEG C. and pressures from 5 to 500 bars. Hydrogenation is carried out continuously on a catalyst that contains 80 to 98% by weight cobalt oxide, 1 to 10% by weight manganese oxide, 1 to 10% by weight phosphorus pentoxide and 0 to 5% by weight alkali metal oxides
