A process for the preparation of 1,4-butynediol and related catalyst

Verfahren zur Herstellung von 1.4-Butindiol und Katalysator hierfür

Procédé de préparation de 1,4-butyne-diol et catalyseur à cet effet

Abstract

The process for the preparation of 1,4-butynediol through the reaction of acetylene and formaldehyde in the presence of copper as the catalyst is improved, both as regards the production rate and as regards the selectivity, in that a catalyst is used comprising a complex of copper with a polymer of 4-vinylpyridine as the support; the polymer can be either a homopolymer preferable swelled with a solvent inert with respect to the reaction mixture under the reaction conditions, or a copolymer of 4-vinylpyridine with a vinylaliphatic or vinylaromatic comonomer. Moreover the use of the catalist of the invention prevents the acetylene polymer, namely cuprene, from being formed.
