Abstract
The present invention relates to methods for production of arylsulfides wherein an aromatic compound is reacted with elemental sulfur in the presence of solid acid catalyst. The solid acid catalyst can be a zeolite. The methods are useful for producing alkylated diphenylsulfides from aromatic compounds and elemental sulfur.
Claims21
A method for the production of an alkylated diphenylsulfide comprising reacting an alkylated aromatic compound with elemental sulfur in the presence of at least one zeolite selected from MCM-56, ZSM-5, MCM-22, MCM-68, and USY.
A method for the production of an alkylated diphenylsulfide comprising reacting an alkylated aromatic compound with elemental sulfur in the presence of a solid acid catalyst wherein the solid acid catalyst is selected from a large pore zeolite and a medium pore zeolite.
A method for the production of an alkylated diphenylsulfide comprising reacting an aromatic compound with elemental sulfur and an alkylating agent in the presence of a solid acid catalyst wherein the catalyst is a zeolite.
A method for the production of an alkylated diphenylsulfide comprising reacting an aromatic compound with elemental sulfur and an alkylating agent in the presence of a solid acid catalyst, wherein the solid acid catalyst is at least one zeolite selected from a large pore zeolite and a medium pore zeolite.
A method for the production of an arylsulfide comprising reacting an aromatic compound with elemental sulfur in the presence of a solid acid catalyst, wherein the catalyst is a medium pore zeolite catalyst.
A method for the production of an arylsulfide comprising reacting an aromatic compound with elemental sulfur in the presence of a solid acid catalyst, wherein the catalyst is a large pore zeolite catalyst.
