Alkylation and dealkylation of aromatics in the presence of crystalline aluminosilicates
TLDR
In this article, a process for alkylating or dealkylating a compound capable of alkylation or denoising a compound by contacting it in a reaction zone maintained under conditions effective for accomplishing said alkylation with a catalyst comprising a crystalline zeolite characterized by a unique X-ray diffraction pattern or products of thermal treatment of the zeolate.Abstract:
A process for alkylating or dealkylating a compound capable of alkylation or dealkylation by contacting it in a reaction zone maintained under conditions effective for accomplishing said alkylation or dealkylation with a catalyst comprising a crystalline zeolite characterized by a unique X-ray diffraction pattern or products of thermal treatment of the zeolite. The zeolite can be further defined by reference to the following formula expressed in terms of mole ratios of oxides: WHEREIN M is a cation, J is aluminum or gallium and Z is silicon or germanium and n is the valence of M.read more

Alkylation of aromatic compounds in the presence of an alumino-silicate catalyst
TL;DR: In this paper, a process for producing alkylated organic compounds comprises effecting reaction of an alkylating agent and an aromatic hydrocarbon, or aromatic hydrocarbons containing a nonpolar substituent, at a temperature not in excess of 600 DEG F, in the presence of a superactive catalyst comprising a base-exchanged crystalline aluminosilicate having a residual sodium content not greater than 6% by weight of the dry aluminosa and a pore size of 6 to 15 Angstrom units; said catalyst having an activity constant above 10.
