Abstract

1284326 Acetone and cresol MITSUI PETROCHEMICAL INDUSTRIES Ltd 12 June 1970 [18 June 1969] 28662/70 Heading C2C Cresol and acetone are prepared from cymene hydroperoxide by subjecting a liquid oxidation product of cymene containing at least 50 weight per cent of cymene hydroperoxide to an acidcatalysed cleavage at a temperature of 60-90‹ C. until the concentration of cymene hydroperoxide in the liquid is 0À5-5 weight per cent neutralizing the incompletely cleaved product with a base to stop the acid catalysed cleavage, thermally decomposing the cymene hydroperoxide remaining in the oil phase of the neutralized product and recovering cresol and acetone from the products of the thermal decomposition.
