Preparation of alkanediols from alkynols
A process for the preparation of alkanediols by hydrogenation of alkynediols of from 3 to 8 carbon atoms in which a solution of the alkynediol in an alcohol of from 1 to 8 carbon atoms, the mass fraction of alkynediol being more than 5%, of water at most 10%, and of alkanediol from 20% to 85%, is hy...
