| Abstract: | The synthetic process for producing benzotrichloride by chlorination of toluene with photocatalyst was improved.By using benzoyl peroxide(Ⅰ) as catalyst,triethanolamine (Ⅱ) as byproduct inhibitor,selecting the weight ratio of toluene, Ⅰ and Ⅱ as 1340∶25∶1,reacting with 7h,the yield of benzotrichloride reached 96.0%,and the purity was 99%。 |
