METHOD OF ALKYLATION OF BENZENE WITH ISOPROPYL ALCOHOL OR MIXTURE OF ISOPROPYL ALCOHOL AND PROPYLENE

摘要

FIELD: chemistry.;SUBSTANCE: claimed invention relates to method of increasing productivity of catalyst of benzene alkylation with isopropyl alcohol or mixture of isopropyl alcohol and propylene, which includes realisation of said reaction of alkylation under conditions of temperature and pressure, completely corresponding to gas phase of reagents and at least partially to liquid phase of reaction products, in presence of catalytic system, containing zeolite, of MTW type. Invention relates to method of phenol obtaining.;EFFECT: application of claimed invention makes it possible to ensure better results with respect to characteristics, term of catalyst service and, accordingly, productivity, even in presence of considerable amounts of water.;16 cl, 5 ex, 2 dwg
