Abstract: The dioctyl glycerol ether sulfate anionic surfactant was synthesized from glycerol. The intermediate dioctyl glycerol ether was confirmed by IR and MS. Various influencing factors for synthesis of dioctyl glycerol ether synthesizing，such as molar ratio，reaction temperature and reaction time were studied. The optimal reaction condition was obtained by the ratio of sodium octoxide and dichloropropanol is 2.2∶1，reaction temperature is 70 ℃ with reaction time of 8 h. Under this condition，the yield of dioctyl glycerol ether exceeds 92% as measured by GC. Dioctyl glycerol ether sulfate was prepared by chlorosulfonic acid and its surface activity was measured. The results showed that it has good capacity for surface tension reducing and low critical micelle concentration.
