Patent ID: 8198496

Claim:
A process for manufacturing a mono-alkylaromatic aromatic compound, said process comprising contacting a feedstock comprising an alkylatable aromatic compound and an alkylating agent under alkylation reaction conditions with a EMM-13 catalyst, to form said mono-alkylaromatic compound, said EMM-13 catalyst comprising a molecular sieve having a framework of tetrahedral atoms (T) bridged by oxygen atoms (O), said tetrahedral atom framework being defined by a unit cell having dimensions of a=b=0.14198(2) and c=0.27647(7) in nanometers, wherein x/a, y/b, z/c are the fractional coordinates of each atom of said unit cell, Uiso is the isotropic temperature factor for each atom in Å 2 (Angstrom units) 2 , and the quantity ‘occ’ is the occupancy factor for each atom, said unit cell having atomic coordinates in nanometers shown in the following table: Atom x/a y/b z/c Uiso occ.
