Description
The present invention relates to a kind of method from fluorohaloparaffin or the synthetic fluorine-containing hydrocarbyl sulfonate of Fluorine containing olefine.Specifically under the organic amine compound and solvent system that have lone pair electron on dehalogenation sulfonated reagent, the nitrogen-atoms, fluorohaloparaffin or fluorine-containing haloolefin are prepared the method for fluorine-containing hydrocarbyl sulfonate, in other words, also be a kind of dehalogenation sulfonation and sulfonation reaction.
At Synthetic Organic Chemistry and medicine, in dyestuff synthetic, the fluorine-containing alkylsulphonic acid of short chain is used very extensive, and they can be used as the catalyzer and the reaction reagent of many organic reactions.Especially trifluoromethane sulfonic acid can carry out various gentlenesses as strong acid reagent, efficiently reaches spatial selectivity organic transformation preferably, provides possibility for realizing many new building-up reactionss.At present, the way of electrofluorination is adopted in the preparation of trifluoromethane sulfonic acid or perfluoro alkyl sulfonic acid mostly, this method cost height, toxicity are big, and concerning β-hydrogen perfluoro alkyl sulfonic acid, the normal alkali aqueous solution that adopts Fluorine containing olefine and sodium bisulfite causes by superoxide in high temperature, autoclave and prepares.This process exists severe reaction conditions, and productive rate is low, and the reaction specificity is not strong, shortcomings such as cost height.
Once reported [U.S.P.2403207(1946); U.S.P.2409274(1947)] addition reaction of tetrafluoroethylene, perfluoro propylene and sodium bisulfite excessively, but the conditional request of reaction is relatively harsher, contain a large amount of boraxs in the requirement system, and temperature of reaction to need also superoxide to cause between 100-120 ℃.Produce the tetrafluoroethylene polymerization problem in the reaction process, the sulfonate of Sheng Chenging hydrolysis easily with this understanding then, and have the side reaction of tetrafluoroethylene and water addition, the HCF of generation a great deal of in the reaction product
2CNa causes difficulty for the separation of product.Thereby the preparation method of research fluorine carbon sulfonate, seek under mild conditions fluorine-containing hydrocarbyl sulfonate of high productivity synthesizing new and derivative thereof and be still a research topic highly significant.
The purpose of this invention is to provide a kind of fluorohaloparaffin with cheapness, fluorine-containing haloolefin is a raw material, has the organic amine compound of lone pair electron on nitrogen-atoms, dehalogenation sulfonated reagent and solvent exist down, prepare the method for fluorine-containing hydrocarbyl sulfonate.This salt can obtain derivatives such as fluorine-containing hydrocarbyl sulfonic and fluorine-containing sulfonic acid chloride thereof respectively again through acidifying and chloride.
