Technical silicon trichloride is a product with a purity of over 97%.It is used as a raw material / intermediate in the production of organofunctional silanes and other silicon-based substances.Organofunctional silane derivatives are used in the CASE industry, the production of glass fibres, as a coupling agent, or in the rubber industry.
Silicon trichloride is used as a precursor for the preparation of a number of organofunctional silanes, e.g. vinyltrimethoxysilane, aminopropyltrimethoxysilane, chloropropyltrimethoxysilane and glycidoxypriopyltrimethoxysilane. These compounds are being widely applied in the preparation of resins or complex composites for use in the rubber industry, the CASE industry, foundry, to modify the properties of surfaces by giving them specific features.
It is the basic raw material for the production of octadecyltrichlorosilane, perfluorooctyltrichlorosilane and perfluorodecyltrichlorosilane. These chlorosilanes form a self-assembled monolayer (SAM) on various substrates. They are mainly used to modify surfaces by giving them superhydrophobic properties. They are biocompatible polymers with a low surface energy. They also exhibit anti-fouling properties with high wettability, which facilitates the release of various composites from the mold.
Silicon trichloride is also used for the production of a TESPN – 3-(triethoxysilyl)propylnitrile – derivative, which is used in the production of DSSC cells (dye-sensitized solar cells) and in the development of PVDf-based ultrafiltration membranes for anti-fouling applications. TESPN can also be used in the synthesis of SBA-15 to create mesoporous silica for drug delivery applications as well as an alternative to the traditional metal chromium-plating technology.
At a normal temperature and pressure, silicon trichloride is a liquid with a melting point of -126.5°C and a boiling point of 31.5-33°C. Its density is greater than the density of water (1.33-1.35 g/cm3) at 20°C and it has a moderate (dynamic) viscosity of 0.33 mPa.s at 20°C. It is highly volatile with a vapour pressure of 72,200 Pa at 22.5°C.
The substance is classified as extremely flammable based on its flash point, <-19.5°C, and boiling point, of 31.5-33°C. It is decomposed by water to hydrochloric acid and hydrogen. This reaction occurs very violently. In moist conditions, the product is corrosive to metals and tissues. It is miscible with benzene, chloroform, carbon tetrachloride, ether and heptane. At a standard temperature and pressure, it has the form of a transparent liquid.
PCC Rokita SA is one of the largest chemical companies in Poland as well as Central and Eastern Europe. Its activity includes the production of chloroalkali, polyether polyols, polyalkylene glycols and phosphorus derivatives.
