| 摘要 |
<p>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.</p> |
