More Information
Summary:Disclosed is an equipment and a process for processing of a product stream (a) comprising acetic acid, unreacted cyclohexanone, reaction water and organic heavy ends, said product stream (a) being yielded in a caprolactone production wherein peraceiic acid is generated from acetic acid and hydrogen peroxide and wherein said peracetic acid is subjected to a Baeyer- Villiger reaction with cyclohexanone. Said equipment comprises, in embodiments of the present invention a divided wall column (1) comprising an upper section (2), a bottom section (3), a feed section (4) and a take-off section (5), a separator (9), a distillation column (20) and optionally a distillation column (15).
