Abstract

Acetone, which is contaminated with aldehydes, acids and esters, is purified by intimately mixing with a volumetric excess of 10-30 per cent w/w aqueous caustic solution, separating the phases before any substantial condensation of the acetone has taken place and distilling the acetone. The crude acetone may be derived, for example, from the acid cleavage of cumol hydroperoxide. The mixing is preferably effected in a centrifugal or turbo pump using at least 5 parts by volume of alkali to 1 part of acetone. After the separation step the alkali may be recycled, being replaced by fresh from time to time and the used alkali withdrawn. Water is preferably added to the acetone before treatment in order to replace that absorbed by the acetone from the alkali. It is expedient to add water (e.g. 1-2 per cent based on the acetone) to one of the lower plates of the distillation column above the inlet level. An example is given.
