| Abstract: | Trichloroethanol was prepared by one pot method with aluminite powder,paraldehyde,ethanol and ethyl acetate.The two step reaction using the same solvent,the intermediates are not isolated.The effects of material ratio,reaction solvent,reaction time and other factors on the yield of the reaction were investigated.The result showed that the optimum process conditions were as follows ∶n（aluminite powder） ∶ n （ethanol） ∶ n （paraldehyde） =1 ∶ 3.8∶ 2.4,solvent ethyl acetate 60 g for condensation reaction,condensation refluxed for 26 h,the yield was 80.4％. |
