Abstract

PURPOSE:To obtain a dealkylation catalyst improved in high-temp. resistance and enhanced in catalystic activity by forming the catalyst contg. the modified saponite, as shown by a specified formula, obtained by applying metal ion exchange to saponite and sintering the obtained material. CONSTITUTION:An aq. soln. of >=1 kind among the nitrate, sulfate, phosphate, etc., of groups IIa, IIIa, IIIb, and IVa elements and group VIII iron-family elements is prepared. Saponite is dispersed and dipped in the aq. metal ion soln., ion exchange is carried out for a specified time, and the ion-exchange saponite is filtered out, washed with water, and then sintered at a prescribed temp. for a specified time to produce the dealkylation catalyst. The catalyst has a composition expressed by formula I [M<n+> is a metal ion and (n) is an integer of 2-5], and is appropriately used for the dealkylation of an alkyl aromatic compd.
