2-Hydroxy-4-octyloxybenzophenone was synthesized from 2,4-dihydroxybenzophenone and octyl chloride in the presence of N-octyl-diethanolamine borate,which was synthesized from diethanolamine borate and octyl bromide.When the molar ratio of 2,4-dihydroxybenzophenone to octyl chloride was 1:1.05,reaction temperature was 155~160℃,reaction time was 8 h and m(N-octyl-diethanolamine borate)/m(2,4-dihydroxybenzophenone)=0.05,the purity of the alkylated product was 98.5%,and the yield was 92.3%.
