| Abstract: | A silicon-halogen synergistic flame retardant tetrachloropropyl silicate was synthesized by using silicon tetrachloride and propylene oxide as raw materials.The effect of reaction time,temperature and ratio of reagents on product yield was investigated.The optimal conditions for preparation of tetrachloropropyl silicate were as follows: n(silicon tetrachloride)∶n(propylene oxide) was 1∶4.2;and the reaction time was 6 h at 75 °C The product yield of tetrachloropropyl silicate could reach 98.5%.The molecular structures of tetrachloropropyl silicate and its related performance measurement were determined by means of FT IR,1H NMR techniques and LOI. |
