| Chemical Properties | Phenyl trichlorosilane is a colorless to light yellow liquid. |
| Uses | Phenyltrichlorosilane can be used in the development of high-capacitance polymer dielectric for low-voltage organic transistors. |
| Preparation | The high-temperature condensation (HTC) technique proved to be very convenient and economical for the production of phenyltrichlorosilane and in recent years has become one of the main industrial techniques for its synthesis. The synthesis of phenyltrichlorosilane by HTC technique is conducted according to the reaction: HSiCI3 + C6H5CI →（HCI）→ C6H5SiCI3 In this case, similarly to the vinyltrichlorosilane case, in the conditions of synthesis (600-640 °C) there is a secondary reaction of reduction, which forms silicon tetrachloride and benzene. However, if the process is conducted in the presence of an initiator (5% of diazomethane), it is possible to reduce the temperature down to 500-550 °C. Then the secondary reaction proceeds very slowly, which increases the yield of phenyltrichlorosilane by 1.5 times. To suppress the reduction process, one can also add benzene and silicon tetrachloride into the reactive mixture. It is also possible to boost the yield of phenyltrichlorosilane and increase the degree of the chlorobenzene transformation by using two subsequent reactors. |
| General Description | A colorless liquid with a pungent odor. Flash point 91°F. Decomposed by moisture or water to hydrochloric acid with evolution of heat. Corrosive to metals and tissue. |
| Reactivity Profile | Chlorosilanes, such as Phenyltrichlorosilane are compounds in which silicon is bonded to from one to four chlorine atoms with other bonds to hydrogen and/or alkyl groups. Chlorosilanes react with water, moist air, or steam to produce heat and toxic, corrosive fumes of hydrogen chloride. They may also produce flammable gaseous H2. They can serve as chlorination agents. Chlorosilanes react vigorously with both organic and inorganic acids and with bases to generate toxic or flammable gases. |
| Health Hazard | Highly toxic; may cause death or permanent injury after short inhalation exposure to small quantity. Chemical burns to all exposed membranes and tissues with severe tissue destruction. Inhalation -- lungs may fill up with fluid or throat may swell causing suffocation. Eyes -- damage to corneas may cause blindness. Delayed: after oral exposure stomach and intestines may perforate or be obstructed by scar tissue. |
| Flammability and Explosibility | Non flammable |
| Potential Exposure | Phenyl trichlorosilane is used to make silicones for water repellants, insulating resins; heat resistant paints; and as a laboratory reagent |
