ABSTRACT:
Continuously passing a mixture of an acetylenic alcohol and a siloxane compound having at least three silicon-bonded hydrogen atoms bonded to at least three different silicon atoms in the presence of a platinum catalyst through a heating means wherein the mixture is heated above 100.degree.C. and above the temperature at which the olefinic siloxane compound product is no longer an inhibitor for the reaction and wherein the reactants and products are maintained under sufficient pressure to keep the mixture in a liquid state at least until the mixture has passed through the heating means provides an olefinic siloxane compound which, below 100.degree.C, is an inhibitor for the reaction between the acetylenic alcohol, the siloxane compound having at least three silicon-bonded hydrogen atoms in the presence of platinum.
