Disclosed is a process for producing 1,2-dichloro-3,3,3-trifluoropropene, which is characterized by that 1-halogeno-3,3,3-trifluoropropene represented by the general formula [1]:
(In the formula, X represents a fluorine atom, chlorine atom or bromine atom.) is reacted with chlorine in a gas phase in the presence of a catalyst. It is possible by this process to produce 1,2-dichloro-3,3,3-trifluoropropene in an industrial scale with good yield by using 1-halogeno-3,3,3-trifluoropropene, which is available with a low price, as the raw material.
本发明公开了一种制备1,2-二氯-3,3,3-三氟丙烯的方法,其特征在于,在催化剂的存在下,将由通式[1]表示的1-卤代-3,3,3-三氟丙烯(式中,X表示氟原子、氯原子或溴原子)与氯在气相中反应。通过该方法,可以使用价格低廉的1-卤代-3,3,3-三氟丙烯作为原材料,在工业规模下高产地制备1,2-二氯-3,3,3-三氟丙烯。
