Patent ID: 8212096

Claim:
A process for the hydroalkylation of an aromatic compound comprising the step of contacting the aromatic compound with hydrogen in the presence of a catalyst system comprising a first hydrogenation metal having hydrogenation activity and a molecular sieve having alkylation activity to produce a cycloalkyl-substituted aromatic compound, wherein said molecular sieve comprises a framework of tetrahedral atoms bridged by oxygen atoms, the tetrahedral atom framework being defined by a unit cell with atomic coordinates in nanometers shown in the following table: Atom x/a y/b z/c Uiso occ.
