ZnO with spindle shape was synthesized by ultrasonic-assisted reflux method. The micrograph and structure of ZnO sample were charactered by SEM, TEM and XRD.The results show that basic content of solution, ultrasonic treatment and the mass of diethanolamine play an important role on the formation of ZnO with spindle shape. The growth mechanism of ZnO with spindle shape was discussed. Furthermore, the optical properties of ZnO with spindle shape were revealed by UV-Vis and fluorescence spectroscopy.

he surfactant which was applied to catalytic cracking of heavy oil was synthesized. The effects of reaction temperature, reaction time, the mixture ratio of raw material, as well as the input amount of catalyst on acid value and saponifying value of this product were studied. The optimal reaction conditions were determined: Reaction temperature is 135 ℃; time is 3 h; the ratio of raw material is 1∶1.2; w(catalyst) is 0.4%.Intensified FCC shows that the surfactant improves distribution of the product, increased yield of light oil, decreased productivity of coke and dry gas.
