Abstract
1374398 Acetone PHENOLCHEMIE GmbH 18 July 1973 [20 July 1972] 34237/73 Heading C2C Acetone is recovered from waste water containing it by washing with cumene in parallel flow or counterflow, separating the phases and distilling the organic phase. The washing may be effected in a plurality of steps. The hot cumene residue from the distillation may be used to preheat the acetone-laden cumene. The waste water may be derived from the manufacture of phenol and acetone by the cumene process and the cumene used for the extraction may be returned to a cumene oxidation reactor.
