ABSTRACT:
Described are catalyst compositions comprising a HAMS-1B crystalline borosilicate molecular sieve incorporated into an inorganic matrix, which have been impregnated with a magnesium compound or with both a phosphorus compound and a magnesium compound, said impregnated compositions having improved para-selectively for toluene alkylation. Such impregnated compositions, when used for the alkylation of toluene using methanol, methylether, ethylene, or propylene yield dialkylbenzene products containing a higher proportion of the para-isomer than corresponding unimpregnated borosilicate-based compositions. When toluene is alkylated with propylene using the impregnated catalyst compositions of this invention, a significant increase in para-selectivity among the cymene isomers is obtained at high total-cymene
-propyltoluene ratios.
