Synthesis of di-t-butyl polysulfide from isobutene, hydrogen sulfide and sulfur was carried out at 125℃ in an autoclave over MFI zeolite catalysts isomorphously framework-substituted with Al, Ga, and B. Performances of the catalysts were studied relative to liquid dicyclohexylamine catalyst. The catalysts were prepared from zeolite powders by kneading with alumina binder, extrusion, calcination, and ion exchange. Liquid products were analyzed with elemental analyzer, X-ray fluorescencedoi:10.1627/jpi.52.128 fatcat:55nzdrfao5gqxc6sbfinommaqm
