The Trichlorosilane with CAS registry number of 10025-78-2 is also known as Silane, trichloro-. The IUPAC name is Trichlorosilicon. It belongs to product categories of Reduction; Si (Classes of Silicon Compounds); Si-Cl Compounds; Si-H Compounds; Silicon Compounds (for Synthesis); Synthetic Organic Chemistry; Trichlorosilanes; Chloro Silanes; POSS Precursors and Intermediates; Protecting and Derivatizing Reagents; RSiCl₃Protection and Derivatization; Silicon-Based; Silsesquioxanes: POSS Nanohybrids. Its EINECS registry number is 233-042-5. In addition, the formula is Cl₃HSi and the molecular weight is 135.45. This chemical is a clear liquid and should be stored in a ventilated, cool and dry place. Besides, it is the basic ingredient used in the production of purified polysilicons.

Physical properties about Trichlorosilane are: (1)ACD/LogP: 4.77 ; (2)ACD/LogD (pH 5.5): 4.77; (3)ACD/LogD (pH 7.4): 4.77; (4)ACD/BCF (pH 5.5): 2501.35; (5)ACD/BCF (pH 7.4): 2501.35; (6)Enthalpy of Vaporization: 26.57 kJ/mol; (7)Boiling Point: 31.8 °C at 760 mmHg; (8)Vapour Pressure: 596 mmHg at 25 °C.

Preparation of Trichlorosilane: it is prepared by blowing hydrogen chloride through a bed of silicon powder at 300°C. The yield is about 80-90%. What's more, the reaction produces byproducts of silicon tetrachloride (chemical formula SiCl₄), hexachlorodisilane (Si₂Cl₆), and dichlorosilane (H₂SiCl₂), which can be separated by distillation.

When you are using this chemical, please be cautious about it. As a chemical, it is spontaneously flammable in air and causes severe burns. It is also harmful by inhalation and if swallowed. Besides, it reacts violently with water and liberates toxic gas. During using it, wear suitable protective clothing, gloves and eye/face protection. Keep container tightly closed and in a well-ventilated place away from sources of ignition. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. If accident happens or you feel unwell seek medical advice immediately.
