发明人：MAJERCZAK VICTORIA ANN; GIBSON MICHAEL STEVEN; ORLANDO ROBERT JAMES
摘要:Process for preparing benzenesulfonate salts from an appropriately substituted acid chloride and a hydroxybenzenesulfonic acid is conducted in the absence of solvent, in a molar excess of acid chloride and in the presence of a phase transfer catalyst selected from quaternary ammonium and quaternary phosphonium salts and the target reaction product. The molar excess of the acid chloride is used to reduce the occurrence of gelation in the product.

摘要:Provided are a solid catalyst which gives a cyclic carbonate at a high yield and a high selectivity, which is stable and which may be readily separated after reaction; and a method of industrially advantageous, inexpensive and safe production of a cyclic carbonate by the use of the catalyst. The catalyst contains an inorganic solid substance having a surface modified with an ionic substance containing a Group 15 element; or contains an ionic substance containing a Group 15 element, and an inorganic solid substance. The modifying group for surface modification of an inorganic solid substance is an ionic substance containing a Group 15 element. The ionic substance containing a Group 15 element is at least one substance selected from organic phosphonium salts, organic ammonium salts, organic arsonium salts and organic antimonium salts.

摘要:This invention belongs to the technical field of inorganic chemical synthesis, relating to a modification method for titanium-silicalite zeolite (TS-1). The feature of the invention is pretreating on the TS-1, the TS-1 after pretreatment is modified by the mixture of TPAOH and alkali salts, the alkali salts can be the compounds containing lithium, sodium and potassium element, and then the modification is performed at last. The benefit of the invention is universal capable to modify the TS-1 synthesized by any method, specially the TS-1 with low cost one, the modification can enhance the catalytic performance on both gas and liquid phase epoxidation of propylene.
