Synthesis method of halogenated butene
-
Paragraph 0095-0098, (2020/05/30)
The invention discloses a synthesis method of halogenated butene. The method comprises: (1) carrying out a fluorination reaction on hexachlorobutadiene and a fluorination reagent, and purifying the obtained reaction product to obtain fluorochlorobutane; and (2) carrying out a dehalogenation reaction on the fluorochlorobutane and a dehalogenation reagent in a first solvent, and purifying the obtained reaction product to obtain the halogenated butene. The method has the advantages of simple process, less three wastes, high yield, low cost and the like.
Method for preparing 1,2,3,4-tetrachlorohexafluorobutane
-
Paragraph 0020-0029, (2019/05/02)
The invention discloses a method for preparing 1,2,3,4-tetrachlorohexafluorobutane. 1,2-dichloro-2-iodo-1,1,2-trifluoroethane and metallic zinc which are used as raw materials undergo a ball milling process under the catalysis of ethyl acetate to obtain the 1,2,3,4-tetrachlorohexafluorobutane. The preparation method provided by the invention has the advantages of greenness, high efficiency and fewthree wastes, and is mainly used for preparing the 1,2,3,4-tetrachlorohexafluorobutane.
