Abstract

Catalysts for the production of alkynols by reacting a carbonyl compound with an acetylene hydrocarbon are made by depositing by impregnation copper and bismuth nitrates on a continuous phase silica gel carrier and heating the thus impregnated carrier within the range of 450 DEG -720 DEG C. for 2-100 hours to decompose the nitrates to the oxides whereby the carrier contains 15-20% Cu and 2-9% Bi. The catalyst may be activated with 10% formaldehyde solution. Examples describe the preparation of typical catalysts and their use to convert acetylene and formaldehyde to 2-butynediol 1:4 and propynol. Specification 807,581 and U.S.A. Specifications 2,232,867, 2,300,969, 2,768,215 and 2,871,273 are referred to.ALSO:In the process of preparing alkynols by causing a carbonyl compound selected from the class consisting of aldehydes and ketones to react in the liquid phase with an acetylene hydrocarbon of formula R.C­CH in which R is hydrogen or a hydrocarbon radical a catalyst is used which comprises 15-20% Cu and 2-9% Bi on a continuous phase silica gel made by impregnating the latter with copper and bismuth nitrates and decomposing them into oxides by heating at 450-720 DEG C. for 2-100 hours.
