Abstract

In the preparation of a catalyst useful for making alkynols from carbonyl compounds and acetylene hydrocarbons, a carrier consisting of continuous phase silica gel having a surface area of from 300-340 sq. m./gm. is impregnated with a HNO3 solution of Bi(NO3)35H2O containing from 2-9% of Bi, the carrier is heated to 95 DEG -150 DEG C. to remove HNO3 and then fired at 450 DEG -500 DEG C. for 2-3 hours before reimpregnating with a HNO3 solution of Cu(NO3)2, repeating the heating and firing stages as above followed by further firing at 500 DEG -700 DEG C. for 2-100 hours so as to yield a catalyst having an average copper content of from 10-20%, 16-25% of copper being found adjacent the catalyst surface. In a modification the carrier has a surface area up to 350 sq. m./gm., the further firing is effected at 500 DEG C. for 2 1/2 hours and at 600 DEG C. for a further 2 1/2 hours such that the catalyst has a uniform copper content of from 14-20% adjacent its surface. Specifications 807,581, 937,887, 937,888 and U.S.A. Specifications 2,300,969 and 2,768,215 are referred to.ALSO:In the preparation of alkynols from carbonyl compounds and acetylene hydrocarbons, a carrier is used consisting of silica gel having a surface area of from 300-400 sq. m./gm. which is impregnated with HNO3 solution of Bi(NO3)3.5H2O containing 2-9% Bi, heated to 95-150 DEG C. to remove HNO3 and then fired at 450-500 DEG C. for 2-3 hours before reimpregnating with a HNO3 solution of Cu(NO3)2, repeating the heating and firing stages as above followed by further firing at 800-700 DEG C. for 2-100 hours so as to yield a catalyst having an average copper content of from 10-20%, 16-25% of the copper being found adjacent the catalyst surface. In an example the conversion of acetylene and formaldehyde to propynol and butynediol is described. Specifications 807,581, 937,887, 937,888 and U.S.A. Specifications 2,300,969 and 2,768,215 are referred to.
