摘要： PURPOSE:To simply obtain partially new fluorocyclopropanes useful as intermediates for medicines, agricultural chemicals, etc., at a low cost. CONSTITUTION:A compound of formula I (n is integer of 1-6; R is H, X, OH, 1-6C alkyl, 2-6C alkenyl, 1-6C alkoxy, R', etc.; X is halogen; R' is COOY; Y is H, 1-6C alkyl, aryl, 1-6C halogenoalkyl, etc.; M is metallic atom or organic base) is fluorinated with a molecular fluorine to readily provide the partially new objective compound of formula II at a low production cost. This reaction is normally carried out under cooling, at ordinary temperature or below or on heating while introducing molecular fluorine. The molecular fluorine is used by diluting the fluorine in an inert gas such as nitrogen or helium. Further, a deacidifying agent may be added to the reaction system in order to prevent influence of HF generated during reaction. Furthermore, in the compound of formula II, a compound of formula III (m is integer of 1-4), especially 1- halogeno-2-fluoro-cyclopropanecarboxylic acid derivative is a new compound.

摘要： The invention provides a process for preparation of hexafluoroacetone characterized by bringing hexafluoro-1,2 -epoxypropane into contact with at least one catalyst selected from the group consisting of titanium oxide catalysts and fluorinated titanium oxide catalysts to isomerize it, and a process for preparation of hexafluoroacetone hydrate characterized by making the hexafluoroacetone prepared by the above process absorbed into water to thereby obtain crude hexafluoroacetone hydrate, neutralizing the crude hexafluoro- acetone hydrate with an alkali, and then distilling the resulting mixture. According to the invention, high-purity hexafluoro- acetone can be obtained by isomerization of hexafluoro-1,2 -epoxypropane with little formation of by-products, and high -purity hexafluoroacetone hydrate substantially free from acid can be also obtained.
