标 题:Synthesis of organohalosilane monomers from conventionally uncleavable Direct Process Residue
发明人：LEWIS KENRICK MARTIN; NEELY JOHN DAVID
权利人:LEWIS KENRICK MARTIN; NEELY JOHN DAVID; MOMENTIVE PERFORMANCE MAT INC
摘要:Disclosed herein is a catalytic process for the synthesis of organohalosilane monomers from tetraorganodihalodisilanes and other compounds that are not cleaved during the conventional hydrochlorination of Direct Process Residue. The process is characterized by the use of a catalyst containing (1) one or more heterocyclic amines and/or one or more heterocyclic ammonium halides, and (2) one or more quaternary Group 15 onium compounds.

标题 :Synthesis of organohalosilane monomers via enhanced cleavage of direct process residue
发明人：LEWIS KENRICK MARTIN; NEELY JOHN DAVID
权利人:LEWIS KENRICK MARTIN; NEELY JOHN DAVID; MOMENTIVE PERFORMANCE MAT INC
摘要:Discloses herein is a catalytic process for producing organohalosilane monomers from a high-boiling residue resulting from the Direct Reaction of an organohalide with silicon. The high-boiling residue contains more conventionally cleavable compounds than conventionally uncleavable compounds. The process includes heating the residue in the presence of a catalyst comprising (1) one or more heterocyclic amines and/or one or more heterocyclic ammonium halides, and (2) one or more quaternary Group 15 onium compounds.

标题 :Process for the synthesis of 2,3,3,3-tetrafluoropropene
发明人：ZHOU CHANGYUE; WANG YONG
权利人:FUJIAN YONGJING TECH CO LTD
摘要:The present invention pertains to a novel process of manufacturing the compound 2,3,3,3-tetrafluoropropene (1234yf). The compound 1234yf is the newest refrigerant with zero OPD (Ozone Depleting Potential) and zero GWP (Global Warming Potential). Thus, the invention relates to a process, involving a carbene generation route, for the manufacture of the compound 2,3,3,3-tetrafluoropropene (1234yf), of the compound 243db (2,3-dichloro-1,1,1-trifluoropropane), and optionally of the compound 2-chloro-1,1,1-trifluoropropene (1233xf) via carbene route and compound 243db (2,3-dichloro-1,1,1-trifluoropropane). The invention also relates to a process for the manufacture of the compound 2,3,3,3-tetrafluoropropene (1234yf), wherein the compound 243db (2,3-dichloro-1,1,1-trifluoropropane) serves as a starting material, for the manufacture of the compound 2,3,3,3-tetrafluoropropene (1234yf). Further, the invention relates to a process for the manufacture of the compound 2,3,3,3-tetrafluoropropene (1234yf), and of the compound 243db (2,3-dichloro-1,1,1-trifluoropropane), the initial starting materials are selected from the group consisting of com-pound 123 (2,2-dichloro-1,1,1-trifluoroethane), compound 124 (2-chloro-1,1,1,2-tetrafluoroethane), and compound 125 (pentafluoroethane).

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.
