| Abstract: | 5-Chloro-2-2-hydroxy-3-tert-butyl-5-(2-methoxycarbonylethyl)-phenyl]-2H-benzotriazole was synthesized from 4-hydroxybenzenepropanoic acid methyl ester and 2nitro-4-chloroaniline via alkylation,diazotization,coupling,hydrogenation and esterification.The yield was 36.83% based on methyl 4-hydroxybenzenepropanoate.The product was characterized by MS and ~1H-NMR.The UV-absorption and light permeating ability were measured.The results indicated that the product is a new and good ultraviolet absorber. |
