Abstract:Diphenylacetic acid was prepared through a series reactions including Friedel-crafts acylation, condensation, saponification and acidification using biphenyl as the starting material. The total yield was 79.3%, and the purity of the product was more than 99.95%. Its structure was confirmed by MS and 1H NMR. The synthesis process of key intermediate acetophenone was improved to reduce side reactions and improve its purity |
Key words:biphenyl; benzophenone; synthesis |
