Abstract
Diarylalkanes are prepared by alkylating an aromatic compound with a styrene derivative in the presence of a catalyst of specific synthetic porous crystalline material. The aromatic compound can be, for example, benzene, toluene, xylene, ethylbenzene, cumene, etc. The styrene derivative can be, for example, styrene, methylstyrene or the like.
Claims3
A method for producing a diarylethane by aralkylating an aromatic hydrocarbon selected from the group consisting of benzine and cumene with styrene under a liquid phase condition in the presence of a synthetic porous crystalline material having the structure of ZSM-12, wherein the molar ratio of the aromatic hydrocarbon to the styrene derivative is at least 10:1.
