Title:
METHOD FOR PRODUCING SULFOLANE COMPOUND
Document Type and Number:
Japanese Patent JP2011201839
Kind Code:
A
Abstract:
To provide a method for easily producing a sulfolane compound used as the extraction solvent of benzene, toluene, xylene, etc., a solvent for producing a liquid crystal or semi-conductor, a reaction solvent of an aromatic compound and a production intermediate of a pest-controlling agent, etc., in a good efficiency.
This method for producing the sulfolane compound expressed by formula (2) [wherein, R1 to R6 are each independently H or 1-6C alkyl] is provided by hydrogenating a sulfolene compound expressed by formula (1) [wherein, the R1 to R6 are each the same as in the formula (1)] in the presence of a metal catalyst and another metal having a higher ionization tendency than that of the metal kind in the metal catalyst.
