标 题:Process for the synthesis of an aluminium modified carbon supported palladium catalyst
发明人：MURTHY JANMANCHI KRISHNA; SHEKAR SRIDARA CHANDRA; RAMARAO KAMARAJU SEETHA; RAJU BURRI DAVID; RAGHAVAN KONDAPURAM VIJAYA
权利人:COUNCIL SCIENT IND RES
摘要:The present invention relates to a process for the synthesis of highly active modifiedncarbon supported palladium catalyst by simultaneously impregnating activated carbon with anpalladium precursor and an aluminium precursor. The carbon supported palladium catalyst isnuseful for the hydrodechlorination of dichlorodifluoromethane to produce difluoromethane.

发明人：MARCHIONNI GIUSEPPE; PAGANO ELVIRA; GUARDA PIER ANTONIO
权利人:SOLVAY SOLEXIS SPA
摘要:A process to obtain perfluoropolyethers comprising:n a) synthesis of peroxidic perfluoropolyethers by one of the following reactions: al) TFE photooxidation, in solvents selected between perfluorocarbons and (mono)hydrofluorocarbons, of general formula:n nC y F( 2y+2−X )H x   (II)n  wherein y is an integer from 2 to 4; x is an integer equal to 0 or 1; in the present of fluorine diluted with an inert gas; or a2) TFE oxidation using as radical initiator fluorine or hypofluorites of formulan nR f OF  (III)n  (R f perfluoroalkyl radical from 1 to 3 carbon atoms), operating from −40° C. to −100° C. at a pressure comprised between 0 and 12 bar; b) thermal treatment of the product obtained in a) at a temperature from 1500° C. to 250° C.; c) treatment with elemental fluorine of the polymer obtained in step b) at temperatures from 100° C. to 250° C., or by treatment with fluorine in the presence of UV radiations, operating at temperatures from −50° C. to 120° C.
