Hydrolysis of Propyl Trimethoxy Silane

In the paper,the hydrolysis of propyl trimethoxy silane(assigned with WD-10)was analyzed by the one-factor experimental method, conductivity detection and FTIR spectroscopy,and then the factors of affecting hydrolysis was discussed,the better technical parameters of hydrolysis were determined.The better technical parameters of hydrolysis are as follows: volumetric ratio of WD-10,secondary distilled water and methanol is 1∶1∶3;pH is 4;hydrolysis is at 30 ℃ for 4 h. This can provide reference for the oleophilic modification of porous ceramics filtering ball and the treatment of wastewater containing oil by coalescence filtration technique.
