De Simone, R E; Haddad, M S

A process is described for making paraxylene by methylating toluene in the presence of a catalyst composition comprising a HAMS-1B crystalline borosilicate molecular sieve. The majority of the crystallites are between about 1 micron and about 15 microns in largest dimension, incorporated into an inorganic matrix. The composition is impregnated by a magnesium compound and subsequently heated to substantially convert the compound to the oxide form.
