Rearrangement reaction between saturated hydrochlorofluorocarbon carbides and method for preparing fluorine-containing alcohols thereby

The invention relates to the technical field of preparation of fluorine-containing alcohol, in particular to preparation of fluorine-containing monohydric alcohol and dihydric alcohol of polyfluoro-substituted alkane. The method comprises a rearrangement reaction between saturated hydrochlorofluorocarbon carbides and comprises the following steps that the saturated hydrochlorofluorocarbon carbides with the general formula of CHmF3-mCHCl(CHX)nCH2Cl are rearranged under the action of a polar solvent and a catalyst to obtain the saturated hydrochlorofluorocarbon carbides with the general formula of CHmF3-mCCl2(CHX)nCH3, X is H or Cl, n is larger than or equal to 0, and m is 0 or 1 or 2. The catalyst is selected from one or more of transition metal oxide and Lewis acid metal halide. The saturated hydrochlorofluorocarbon obtained by rearrangement can react with fuming sulphuric acid to obtain fluorine-containing monohydric alcohol or fluorine-containing dihydric alcohol. The fluorine-containing alcohol is prepared from raw materials which are low in price and easy to obtain through rearrangement, esterification and hydrolysis. The reaction has the characteristics of being simple in process, low in reaction temperature, easy to control, easy to industrialize and high in reaction yield; meanwhile, a rearrangement product in the preparation process is a chemical raw material with potential important industrial value.

COMPOSITIONS AND METHODS FOR SYNTHESIS OF 2,3-DICHLORO-1,1,1,2-TETRAFLUOROPROPANE AND 2,3,3,3-TETRAFLUOROPROPENE

A method of synthesizing 2,3,3,3-tetrafluoropropene (1234yf) from 2-chloro-3,3,3-trifluoropropene (1233xf). The 2-chloro-3,3,3-trifluoropropene (1233xf) is reacted in the vapor phase, in the presence of a catalyst, at a temperature and pressure sufficient to selectively convert the 2-chloro-3,3,3-trifluoropropene (1233xf) to 2,3,3,3-tetrafluoropropene (1234yf) without the use of antimony-based catalysts.
