| titleOfInvention | Process for the addition of hydroxyl group-containing compounds to alkynes or allenes |
| abstract | Process for the preparation of compounds of the formulas I and II in which R 1 is hydrogen or an aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radical or an acyl radical, where these radicals can carry further substituents which do not react with acetylenes or allenes and the radicals R independently of one another are hydrogen or aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radicals, which can be connected to form a ring and m represents 0 or 1, by adding compounds of the formula III R 1 OH to acetylenes or allenes of the formulas IV or V wherein R 1 and R have the meanings given above, in the gas phase at elevated temperature in the presence of a heterogeneous catalyst obtained by impregnating silica with a zinc salt, characterized in that the reaction is carried out at a temperature below 200 ° C and a Catalyst is used which has an X-ray amorphous zinc silicate or cadmium silicate with an zinc or cadmium content, calculated as oxide, of 1 to 40% by weight as an active ingredient, obtainable by applying a salt of zinc or cadmium and an inorganic oxo acid, the is decomposable at temperatures below 400 ° C, on amorphous silica and formation of the catalyst before the reaction at temperatures from 50 to 500 ° C or during the reaction in situ at temperatures from 50 to 200 ° C, in the presence of a compound containing hydroxyl groups, selected from the group consisting of water, alkanols with 1 to 6 carbon atoms or di olen, polyols with 2 to 6 C atoms and 2 to 3 OH groups or carboxylic acids with 1 to 6 C atoms. |
