Abstract:
The present invention relates to a process for preparing a tris[3-(alkoxysilyl)propyl] isocyanurate from the group of tris-[3-(trialkoxysilyl)propyl] isocyanurate, tris[3-(alkyldialkoxysilyl)propyl] isocyanurate and tris[3-(dialkylalkoxysilyl)propyl] isocyanurate by hydrosilylation, by in step A initially charging a mixture comprising at least one hydroalkoxysilane from the group of hydrotrialkoxysilane, hydroalkyldialkoxysilane, hydrodialkylalkoxysilane [called H-silane(s) for short], at least one carboxylic acid and a Pt catalyst, heating the mixture to a temperature of 50 to 140° C., in step B adding a mixture of 1,3,5-triallyl-1,3,5-triazine-2,4,6(1H,3H,5H)-trione and at least one alcohol to the mixture from step A while mixing, in step C leaving the mixture from step B to react while mixing and in step D working up the product mixture thus obtained.

Claim (Index 1):
A process for preparing at least one tris[3-(alkoxysilyl)propyl] isocyanurate selected from the group consisting of tris[3-(trialkoxysilyl)propyl] isocyanurate, tris[3-(alkyldialkoxysilyl)propyl] isocyanurate and tris[3-(dialkylalkoxysilyl)propyl] isocyanurate by hydrosilylation, the process comprising:\n (A) initially charging a mixture comprising at least one H-silane selected from the group consisting of hydrotrialkoxysilane, hydroalkyldialkoxysilane, and hydrodialkylalkoxysilane, with at least one carboxylic acid and a Pt catalyst, and heating the mixture to a temperature of 50 to 140\u00b0 C., (B) adding a mixture of 1,3,5-triallyl-1,3,5-triazine-2,4,6(1H,3H,5H)-trione and at least one alcohol to the mixture obtained in (A) while mixing, (C) leaving the mixture obtained in (B) to react while mixing and (D) working up the product mixture thus obtained.
