ABSTRACT:
A vaporized mixture of a platinum catalyst in the amount of 0.01 to 2 p.p.m. platinum, an acetylenic alcohol and a siloxane compound having at least three silicon-bonded hydrogen atoms per molecule is passed through a tube such as a stainless steel tube heated at 210.degree.C. to 450.degree.C. to produce an olefinic siloxane compound which is, below 100.degree.C., an inhibitor for the reaction between the acetylenic alcohol and the siloxane compound having at least three silicon-bonded hydrogen atoms in the presence of platinum.
