titleOfInvention | Method for preparing phenol and acetone by acid-catalyzed cleavage of cumyl hydroperoxide followed by thermal treatment and reactor for realizing method |
abstract | FIELD: organic chemistry, chemical technology. n SUBSTANCE: invention relates to a method for preparing phenol and acetone by acid-catalyzed cleavage of cumyl hydroperoxide. Method involves preliminary heating the reaction mixture to temperature above 100°C and then for thermal treatment of product heat in exothermic reaction is used, mainly the cleavage reaction of cumyl hydroperoxide that presents in the concentration from 5 to 10 wt.-%. The preferable residual content of dicumyl hydroxide in thermally treated product is 0.01-0.05 wt.-%. Stages in cleavage of cumyl hydroperoxide and the following thermal treatment can be carried out in a single reactor with two zones among that one zone is fitted with a device for heat removing and another zone has a feature of the flow-type pipe. Reactor is equipped by a device for circulation of part of product from thermal treatment zone to a feeding line for decomposition of product. Method provides improving energetic indices of process due to optimal consumption of heat energy in maintaining high selectivity of the decomposition process. n EFFECT: improved preparing method. n 15 cl, 3 dwg |
