The borosilicate is used to catalyze various processes, such as isomerization, disproportionation, alkylation, transalkylation, and conversion of alcohols into gasoline-boiling-range products, olefins, and/or aromatics. Broadly, there is provided a process for the alkylation of an aromatic hydrocarbon, which process comprises contacting a feed comprising said hydrocarbon under alkylation conditions and in the presence of an alkylating agent with a catalyst comprising a crystalline borosilicate which comprises a molecular sieve material providing an X-ray diffraction pattern comprising the following X-ray diffraction lines and assigned strengths: ______________________________________ Assigned d (A) Strength ______________________________________ 11.2 ± 0.2 W-VS 10.0 ± 0.2 W-MS 5.97 ± 0.07 W-M 3.82 ± 0.05 VS 3.70 ± 0.05 MS 3.62 ± 0.05 M-MS 2.97 ± 0.02 W-M 1.99 ± 0.02 VW-M ______________________________________ and having the following composition in terms of mole ratios of oxides: 0.9±0.2 M.sub.2/n O:B.sub.2 O.sub.3 :YSiO.sub.2 :ZH.sub.2 O, wherein M is at least one cation having a valence of n, Y is between 4 and about 600, and Z is between 0 and about 160.
