An alkyl polyglycoside derivative,green surfactant alkyl polyglycoside tartrate(APG-ET),was synthesized.The reaction conditions were determined by orthogonal analysis(minitab software),the conversion of lauryl alkyl glycoside(C12-APG)was analyzed by HPLC,fourier infrared spectroscopy(IR)was used to verify the esterification process.The average conversion rate of double bond was 98.3%by iodometry(GB/T 1677-2008),the average yield of the product was 81.3%,APG-ET was obtained after purification.The equilibrium surface tension of APG-ET is 23.65 mN/m,the critical micelle concentration is 1.54×10-4 mol/L(25℃),and the water solubility was better than that of C12-APG.
