The invention is a selective process for preparing 1,1,1-trichloroethane comprising irradiating a vaporous mixture comprising 1,1-dichloroethane, chlorine and an effective amount of a photocatalyst wherein the photocatalyst is bromine, a compound which liberates bromine in the presence of chlorine, carbon monoxide, nitric oxide or oxygen, with radiation capable of inducing the selective formation of 1,1,1-trichloroethane. Radiation in the wavelength of between about 250 and 550 nanometers is capable of inducing the selective formation of 1,1,1-trichloroethane.
本发明是一种制备 1,1,1-三氯乙烷的选择性工艺,包括用能诱导选择性形成 1,1,1-三氯乙烷的辐射照射由 1,1-二氯乙烷、氯和有效量的光催化剂组成的气态混合物,其中光催化剂是溴,一种在氯、一氧化碳、一氧化氮或氧存在下能释放溴的化合物。波长在 250 至 550 纳米之间的辐射能够诱导 1,1,1- 三氯乙烷的选择性形成。
