<p>Preparation of an alkyl polyether substituted mercaptosilane compound (I) having color index number according to haze of = 250 mg platinum-cobalt/liter comprises: reaction of a mercaptosilane compound (II) with an alkyl polyether compound (III) in the presence of a proton-supplying co-catalyst and optionally another catalyst; and separating released compounds e.g. alcohol and water from the reaction mixture. Preparation of an alkyl polyether substituted mercaptosilane compound of formula ((X) m(X1a) n(X2a) oSi(R 1>-SR 2>) p) (I) having color index number according to haze of = 250 mg platinum-cobalt/liter comprises: reaction of a mercaptosilane compound of formula ((X1a) m+n(X2a) oSi(R 1>-SR 2>) p) (II) with m equivalent of an alkyl polyether compound of formula (H-O-((C(R 3>) 2) w-O) vAlk) (III) in the presence of a proton-supplying co-catalyst and optionally another catalyst; and separation of released compounds (X1a-H) from the reaction mixture. p, m : 1-3; n, o : 0-2, where m+p+n+o is 4; X : alkyl polyether group of formula (O-((C(R 3>) 2) w-O) vAlk); v, w : 1-40; R 3>H, phenyl or optionally branched alkyl; Alk : optionally branched, saturated and substituted aliphatic and/or aromatic univalent 1-35C hydrocarbon; X1a : alkoxy, 2-25C alkenyloxy, 7-35C alkylaryloxy or 7-35C aralkyloxy (all optionally branched), 6-35C aryloxy or OH; X2a : optionally branched alkyl; R 1>optionally branched and saturated aliphatic and/or aromatic divalent 1-30C hydrocarbon (optionally substituted by heteroatom); R 2>CN, H or substituted carbonyl group, -C(Het)-Alk; and Het : doubly bound heteroatom of O, S or NAlk.</p> |
