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

The process for the preparation of 1,4-butynediol through the reaction of acetylene with formaldehyde in the presence of a catalytic metal, preferably copper, is improved by using, as the support of the catalytic metal, a molecular sieve or synthetic zeolite to which the catalytic metal is chemically bonded through an ion exchange reaction. There are obtained increased production rates and selectivity and the polymer of acetylene, namely cuprene, is essentially prevented from being formed.
