Beschreibung
Zusammenfassung:	FIELD: catalysts in industrial organic synthesis. SUBSTANCE: catalyst for synthesis of cumol through benzene alkylation with propylene is composed of 50-99.5 wt % of crystalline silicon phosphates - silicon pyrophosphate or silicon orthophosphate/silicon pyrophosphate mixtures (weight ratio from 4.00: 1 to 0.02:1), the rest (to 99.5 wt %) being amorphous silicophosphates and/or phosphoric acid. EFFECT: increased activity. Катализатор синтеза кумола процесса алкилирования бензола пропиленом содержит в своем составе кристаллические фосфаты кремния в количестве 50 - 99,5 мас.%, остальное до 99,5 мас.% - амфорные силикофосфаты и/или фосфорную кислоту. Кристаллическими фосфатами кремния являются пирофосфат кремния и смесь ортофосфата кремния с пирофосфатом в весовом отношении 4,00 - 0,02.
