Specification

The systematic name of Triethylchlorosilane is chloro(triethyl)silane. With the CAS registry number 994-30-9, it is also named as Silane, chlorotriethyl-. The product's categories are Monochlorosilanes; Protection & Derivatization Reagents (for Synthesis); Si (Classes of Silicon Compounds); Si-Cl Compounds; Synthetic Organic Chemistry; Blocking Agents; Chloro Silanes; Protective Agents; Silylating Agents. It is clear transparent liquid which is sensitive to moisture. It also can react violently with water and may form explosive peroxides. Additionally, this chemical should be sealed in the container which is filled with inert gas and stored in the cool and dry place.

The other characteristics of this product can be summarized as: (1)ACD/LogP: 3.77; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 3.77; (4)ACD/LogD (pH 7.4): 3.77; (5)ACD/BCF (pH 5.5): 431.07; (6)ACD/BCF (pH 7.4): 431.07; (7)ACD/KOC (pH 5.5): 2675.55; (8)ACD/KOC (pH 7.4): 2675.55; (9)#H bond acceptors: 0; (10)#H bond donors: 0; (11)#Freely Rotating Bonds: 3; (12)Polar Surface Area: 0 Å²; (13)Index of Refraction: 1.411; (14)Molar Refractivity: 43.41 cm³; (15)Molar Volume: 174.6 cm³; (16)Polarizability: 17.21×10^-24 cm³; (17)Surface Tension: 19.7 dyne/cm; (18)Density: 0.862 g/cm³; (19)Flash Point: 29.4 °C; (20)Enthalpy of Vaporization: 36.58 kJ/mol; (21)Boiling Point: 144.5 °C at 760 mmHg; (22)Vapour Pressure: 6.39 mmHg at 25°C.

Preparation of Triethylchlorosilane: It can be obtained by triethylsilane. This reaction needs reagent butyric chloride and catalytic agent Ni(acac)₂ at temperature of 90 °C. The reaction time is 2 hours. The yield is 83%.

Uses of Triethylchlorosilane: It is used as raw material and intermediate in the synthesis of organosilicon. And it is also used as capping agent for ethyl silicone oil and ethyl silicone rubber. In addition, it can react with 4-methyl-phenol to get triethyl-p-tolyloxy-silane. This reaction needs reagent imidazole and solvent acetonitrile. The yield is 75%.

When you are using this chemical, please be cautious about it as the following:
It is highly flammable and can cause burns, so people should keep it away from sources of ignition. And it is not only harmful if swallowed, but also irritating to eyes and respiratory system.
