Abstract
A process for making silylisocyanurate reacts silylorganocarbamate in the presence of at least one carboxylate salt selected from the group consisting of ammonium carboxylate, alkali metal carboxylate and alkaline earth metal carboxylate as cracking catalyst to provide silylorganoisocyanate which then undergoes trimerization in the presence of the carboxylate salt to silylorganocyanurate.
Claims20
A process for making silylisocyanurate which compromises cracking silylorganocarbamate in the presence of a catalytically effective amount of, as cracking catalyst, at least one carboxylate salt selected from the group consisting of ammonium carboxylate, alkali metal carboxylate and alkaline earth metal carboxylate to provide silyorganoisocyanate and trimerizing silylorganoisocyanate in the presence of the carboxylate salt to provide silylisocyanurate wherein the process is conducted in the absence of metal alkoxide or tin-containing compound.
