Trivinyl ether of 1,1,1-tris(hydroxymethyl) ethane

A process for making the trivinyl ether of 1,1,1-tris(hydroxymethyl)ethane in a yield of 86% which is characterized by direct vinylation of tris(hydroxymethyl)ethane at 140.degree. C., in the presence of 2% by weight of KOH based upon said tris(hydroxymethyl)ethane as a catalyst, at 100 psi. acetylene pressure, in an inert gas at the same pressure as the acetylene, at a mole ratio o said tris(hydroxymethyl)ethane to said acetylene of 1:3 and isolation of the product in a purity of 99% of 69.degree.-71.degree. C. by distillation under a reduced pressure of 7 mm.
