专利号:US-4393241-A 优先权日:1982-02-01 标 题 :Synthesis of alkoxy and phenoxy substituted aryl sulfides 发明人:HANSON HARRY T; SAPP JR JOHN B 权利人:CELANESE CORP 摘要:Provided is a novel process for the synthesis of aryl sulfides substituted with an alkoxy or phenoxy substituent. The process comprises reacting an alkoxy or phenoxy substituted aromatic compound with a sulfur dihalide, preferably sulfur dichloride, in the presence of an alkali metal tetrafluoroborate catalyst, with the amount of said aromatic reactant compound preferably being sufficient to solvate the sulfur dichloride and catalyst sufficiently to allow the reaction to occur.
专利号:US-3584071-A 优先权日:1968-03-01 标题:Telomerization of ethylene 发明人:MCNULTY JOHN G; WALSH WILLIAM L 权利人:GULF RESEARCH DEVELOPMENT CO 摘要:IN THE POLYMERIZATION OF ETHYLENE TO ALPHA OLEFINS WITH A CATALYST COMPRISING TRIETHYLALUMINUM AND NICKEL THE PRESENCE OF DIPHENYL ETHER IS KNOWN TO INHIBIT PRODUCTION OF ALPHA OLEFINS OF CHAIN LENGTH REQUIRED FOR SYNTHESIS OF BIODEGRADABLE DETERGENTS. HOWEVER, WHEN ETHYLENE IS TELOMERIZED WITH A CATALYST COMPRISING ALKYL ALUMINUM SESQUICHLORIDE AND TITANIUM TETRACHLORIDE THE PRESENCE OF DIPHENYL ETHER IS SHOWN TO HAVE AN OPPOSITE EFFECT WHEREBY THE PRODUCTION OF ALKYL GROUPS OF CHAIN LENGTH REQUIRED FOR SYNTHESIS OF BIODEGRADABLE DETERGENTS IS INCREASED.

专利号:US-2005209355-A1 优先权日:2004-03-22 标 题:[Novel Reactions and the Products of Such Reactions] 发明人:ROITMAN LIPA L 权利人:ROITMAN LIPA L 摘要:A process for the synthesis of novel compounds is described comprising reacting tetrachloroethylene with substances containing active methylene group in the presence of free radical initiators. Also, a process for grafting tetrachloroethylene is described comprising reacting these compounds with polymers containing active methylene group in the presence of free radical initiators. Furthermore, a method of conducting such reactions to high conversion is described, comprising conducting the reactions in the reflux condensate. The present invention provides a novel and high yield route for heretofore unobtainable materials.
