Processes for producing β-hydroxy-ketones and a,β-unsaturated ketones are disclosed which comprise the crossed condensation of an aldehyde with a ketone in the presence of a hydroxide or aikoxide of aikali metal or an aikaline earth metal as catalyst. The products of the process, β-hydroxyketones and a,β-unsaturated ketones, are useful for the preparation of many commercially important products in the chemical process industries including solvents, drug intermediates, flavors and fragrances, other specialty chemical intermediates.
