Abstract
Methyl phenol cyclic silicone (MPCS) and methyl phenyl diethoxy silane (MPDS) are important materials for production of addition-cured liquid silicone rubber. The one step Grignard method was used to synthesize MPDS and the orthogonal test method was applied to optimize the process. The maximum MPDS yield of 60.2% was obtained under molar ratio of magnesium/ methyl triethoxy silane/chlorobenzene of 1/1.5/1.25, reaction time of 2.5 h and reaction temperature of 95 . The hydrolysis and pyrolysis methods were used to synthesize MPCS and the single factor method was applied to optimize the process. The maximum MPCS yield of 72% was achieved with DBS/MPDS mass ratio of 4% and fractional addition of MPDS at 95 . The products were characterized by infrared spectrometer and the results showed that the peaks appeared on the IR spectra were basically in agreement with those of MPDS and MPCS, respectively.
