| Abstract: | Alkyldiphenylether was synthesized with dodecyl,tetradecyl,hexadecyl and diphenyl ether respectively. The best reaction conditions were found through the application of normal phase high performance liquid chromatography. The N-HPLC system consisted of C18 kromasil column（5μm, 250×4.6mm） and bexane-isopropylalcohol （18 ： 1）as the mobile phase. The detective wavelength was 274nm.The flow rate was 1.0mL/min and the temperature was 50℃. Alkylation was carded out with n （diphenyl ether） ： n （catalyst）=1 ： 2 under 75℃ for 6h .The yields of dodecyl, tetradecyl, hexadecyl diphenyl ether were respectively 79.62%,72.38%,66.83%. |
