Patent number: 5104998Abstract: A novel organopolysiloxane compound, which has high surface activity to form an emulsion of the water-in-oil type of various hardly emulsifiable materials, is proposed. The organopolysiloxane compound is a dimethylpolysiloxane having two types of modifying groups including polyether or polyoxyalkylene groups on one hand and higher alkyl groups bonded to the silicon atoms through an ether linkage on the other hand bonded to the silicon atoms. Different from conventional dually modified dimethylpolysiloxanes as an emulsifying agent having modifying groups of polyether groups and higher alkyl groups directly bonded to the silicon atoms, the dually modified dimethylpolysiloxane of the invention can be synthesized easily in a one-step process of the reaction in addition to the advantage of excellent emulsifying activity for various kinds of hardly emulsifiable liquids as compared with conventional emulsifying agents.Type: GrantFiled: May 21, 1991Date of Patent: April 14, 1992Assignee: Shin-Etsu Chemical Co., Ltd.Inventor: Shoji Ichinohe

Patent number: 5101068Abstract: The preparation of magnesium benzyl fluoromalonate and other equivalent materials, the synthetic equivalents of the --CH.sub.2 F moiety, is described. Reaction between these reagents and the in situ-formed imidazolides of various carboxylic acids gives beta-keto-alpha-fluoroesters, which upon hydrogenation and spontaneous decarboxylation yields fluoromethyl ketones in excellent yields. The overall transformation from RCOOH to RCOCH.sub.2 F is thus illustrated.Type: GrantFiled: February 16, 1990Date of Patent: March 31, 1992Assignee: Prototek Inc.Inventor: James T. Palmer
