The present disclosure provides a method for producing HFC-143 that is not expensive, and that is more efficient than conventional methods. Specifically, the present disclosure provides a method for producing 1,1,2-trifluoroethane (HFC-143) that includes contacting at least one chlorine-containing compound selected from the group consisting of 1,1,2-trichloroethane (HCC-140), 1,2-dichloro-1-fluoroethane (HCFC-141), 1,1-dichloro-2-fluoroethane (HCFC-141a), (E,Z)-1,2-dichloroethylene (HCO-1130 (E,Z)), and (E,Z)-1-chloro-2-fluoroethylene (HCFO-1131 (E,Z)) with hydrogen fluoride to perform one or more fluorination reactions, thereby obtaining a reaction gas containing HFC-143, hydrogen chloride, and hydrogen fluoride.
本公开提供了一种生产不昂贵且比传统方法更有效的HFC-143的方法。具体而言,本公开提供了一种生产1,1,2-三氟乙烷(HFC-143)的方法,包括将至少一种含氯化合物与氢氟酸接触,所述至少一种含氯化合物从以下组中选择:1,1,2-三氯乙烷(HCC-140)、1,2-二氯-1-氟乙烷(HCFC-141)、1,1-二氯-2-氟乙烷(HCFC-141a)、(E,Z)-1,2-二氯乙烯(HCO-1130(E,Z))和(E,Z)-1-氯-2-氟乙烯(HCFO-1131(E,Z)),以进行一个或多个氟化反应,从而获得含有HFC-143、氯化氢和氢氟酸的反应气体。
