Co-pyrolysis of 1,1,2-trichloroethane (TCE) and methanol on various activated alumina catalysts was carried out at 270°C. As the base amount of catalysts increased, the conversion of TCE and the ratio of 1,1-dichloroethylene to 1, 2-dichloroethylene were found to increase. The results of pyrolysis of TCE with several different alcohols and ethers on activated alumina at 280°C showed the decreasing reactivity in the following order: Et2O>n-PrOH>EtOH >MeOH>n-Bu2O>n-BuOH>n-BuOH>t-BuOH>s-BuOH>i-BuOH>i-Pr2O>i-PrOH. The higher homologs of the normal alcohol series increased the conversion of TCE. The nucleophilicity of the alcohol adsorbed on the basic site of activated alumina might be appreciably enhanced by the inductive effect of alkyl group. However, the reactivity of higher alcohols was decreased owing to the steric hindrance of the bulky alkyl group. On the other hand, it was found that branched alcohols were readily dehydrated to form olefins and the conversion of TCE was lower than that of normal alcohols. The co-pyrolysis of TCE and ethers was analogous to that of alcohols. © 1975, The Chemical Society of Japan. All rights reserved.
