Selective alkylation of aromatic hydrocarbons

A method for increasing selectivity of alkylation to monoalkylation comprising: providing a feedstream consisting essentially of alkylating agent and a stoichiometric excess of benzene, the alkylating agent consisting essentially of a molar blend of propylene and one or more linear butene(s); and, contacting the feedstream with a catalytically effective amount of zeolite beta under alkylation reaction conditions which increase selectivity of the alkylation to monoalkylation compared to predicted selectivity to monoalkylation based on the concentration of the alkylating agent and on the molar blend of propylene and one or more linear butene(s).

Alkylation of benzene with 1-butene in the presence of AlCl3

The catalytic alkylation of benzene with 1-butene at 20-50×C and varied amounts of the AlCl3 catalyst was studied with the aim of optimization of the method of synthesis of sec-butylbenzene. By means of NMR and IR spectroscopy it was shown that together with the main product, sec-butylbenzene the reaction gives 1,3- and 1,4-di-sec-butylbenzenes. The alkylation conditions that allow preparation of sec-butylbenzene and its subsequent isomerization to isobutylbenzene were found.

The Influence of the Conditions of Synthesis of Aluminosilicates from Tetraethoxysilane and Aluminium Nitrate on Their Activity in the Alkylation Reaction. II. The Influence of the Sequence of Hydrolitic Reactions and the Drying Temperature

The paper reports the physical properties and activities, in the alkylation of benzene by propene and butenes, of aluminosilicates synthesised using different sequences of hydrolytic reactions between tetraethoxysilane and an aqueous aluminium nitrate solution and different hydrogel drying temperatures.
