标题:Dehalogenation Of 1,1,2-Trichloro-1-Fluoroethane Over α-Cr2O3 (101̄2)
摘要:The Reaction Of Cfcl2Ch2Cl Over The Stoichiometric Cr2O3 (10 (1) Over Bar2) Surface Yields Cfcl=ch2,Hcdropch,And Surface Halogen. The 1,2-Dihalo-Elimination Reaction To Cfcl=ch2 Is Initiated Via C-Cl Bond Cleavage At The Cfcl2-End Of The Molecule To Give A-Cfcich2Cl Haloalkyl Surface Intermediate. A Rate-Limiting Beta-Chlorine Elimination From The Surface Alkyl Gives Rise To The Cfcl=ch2 Product. Acetylene Is Formed By The Subsequent Reaction Of Cfcl=ch2 In Series. The Chlorine Liberated From Cfcl2Ch2Cl Binds At The Five-Coordinate Surface Cr3+ Sites On The Stoichiometric Surface And Shuts Down The Dehalogenation Chemistry By Site Blocking. No Carbon Buildup Is Observed On Deactivated Surfaces,And No Evidence Is Seen For The Replacement Of Surface Lattice Oxygen By Halogen Under The Conditions Of This Study. At Elevated Temperatures,The Thermal Removal Of Surface Chlorine Is Observed,And It Is Attributed To Migration Into The Sample Bulk.

标 题 :Manganese catalyzed photopolymerization of fluorinated monomers
发明人：ASANDEI ALEXANDRU D
权利人:UNIV CONNECTICUT
摘要:The disclosure discloses initiating systems for the radical polymerization of alkenes, and especially fluorine substituted alkenes. The polymerization is catalyzed by a metal carbonyl, preferably manganese carbonyl. The polymerization is initiated directly from alkyl halides at room temperature under visible white light. The polymers also allow the synthesis of block copolymers. The process comprises polymerizing at least one alkene monomer in the presence of a halide radical initiator, carbonyl catalyst and a solvent, under reaction conditions and for a time sufficient to polymerize the at least one alkene monomer to form a polymer. The present disclosure provides a method for living polymerization of alkene monomers which provides a high level of macromolecular control over the polymerization process and which leads to uniform and controllable polymeric products. This disclosure also provides a method for activating any halide (Cl, Br, I) chain ends of such polymers for the synthesis of block copolymerizations.

标 题 :Catalyst synthesis of halogenated compounds with catalyst regeneration with elemental halogen
发明人：BRAUN MAX; BROSCH CARSTEN
权利人:SOLVAY FLUOR & DERIVATE
摘要:Catalysts such as antimony halides, which are useful in fluorination reactions involving hydrogen fluoride, may be reduced during the reaction and require regeneration. Regenerative oxidation is usually carried out by introducing elemental halogen, preferably fluorine or chlorine, into the reaction mixture. In accordance with the invention elemental halogen is prevented from coming into contact with starting materials or intermediate products which are reactive therewith. This is preferably achieved by withdrawing part of the reaction mixture from the reactor, mixing the withdrawn part with chlorine or fluorine in order to regenerate the catalyst, and thereafter returning the withdrawn part to the reactor.

标 题 :Free radical and controlled radical polymerization processes using azide radical initiators
发明人：ASANDEI ALEXANDRU D
权利人:UNIV CONNECTICUT
摘要:A process is described comprising polymerizing at least one unsaturated monomer (e.g., fluorine substituted alkene monomer) in the presence of an azide radical initiator and a solvent, under reaction conditions and for a time sufficient to polymerize the at least one unsaturated monomer to form a polymer. The present disclosure provides a method for the synthesis of polymers with 100% azide chain end functionality, for living/controlled radical polymerization of unsaturated monomers (e.g., fluorine substituted alkene monomers) and for the synthesis of complex polymer architectures, using azide click reactions.
