标题:Synthesis of aromatic polyhalogenated halomethyl compounds
发明人：KORNBERG NURIT; ADDA MICHAEL; PELED MICHAEL
权利人:BROMINE COMPOUNDS LTD
摘要:The present invention discloses a process for the preparation of highly pure pentabromobenzyl bromide, PBB-Br, wherein the benzylic bromination reaction is carried out in a suitable organic solvent in the presence of water and wherein the reaction temperature is such that it is sufficient to activate the initiator but not high enough to consume a substantial amount thereof.

发明人：KELLER TEDDY M; KOLEL-VEETIL MANOJ K
权利人:US NAVY
摘要:A crosslinked polymer and process of making it are disclosed. A copolymer having at least one alkyne group, carborane group, and alkylsiloxane group is reacted with a siloxane crosslinker in a hydrosilation reaction. This produces a crosslinked polymer where the crosslink sites are reacted alkyne groups.

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.

标 题 :Process for disposing of residues deriving from the synthesis of chlorinated hydrocarbons
发明人：LORENZONI LORENO; MESSINA GIUSEPPE; BRUZZI VITTORIO; SIMULA SALVATORE
权利人:ENICHEM ANIC SPA
摘要:The disposal of chlorinated pitches is carried out by a process which employs two treatments with an alcohol, which are carried out in cascade. n Such treatments cause the precipitation of the suspended matter to take place. This is then caused to settle, and is separated and pyrolized, while the supernatant is distilled in order to separate the alcohol, which is recycled back to the process, from other organic components, which are sent to further uses.
