Process for the preparation of &agr;-diketones from ketols or ketals from ketols

The invention relates to a method for producing alkyne diols by reacting ketones with acetylenic hydrocarbons in an organic solvent in the presence of a base which contains potassium alcoholates of primary and/or secondary alcohols. The alkyne diols are produced while forming adducts which precipitate out of the reaction mixture and which are comprised of alkyne monoalcohols and/or alkyne diols and a base. The stoichiometries of the reaction partners are selected such that gelatinous adducts are formed which comprise a spherical surface, whereby the reaction mixture remains agitable during the entire reaction.

Preparation of sugar alcohols

An alkinol or mixture of two or more thereof is hydrogenated by bringing the alkinol or the mixture of two or more thereof into contact with a hydrogen-containing gas in the presence of a catalyst comprising as active metal at least one metal of transition group VIII of the Periodic Table, either alone or together with at least one metal of transition group I or VII of the Periodic Table, applied to a support, wherein the support contains macropores.
