Thionyl chloride, chloride thionyl, SOCb, slow-burning liquid. The ohm - m, violently interacts with water and forms a large number of gaseous products.
Thionyl chloride represents full anhydride of sulphurous acid. Transparent, colourless or yellowish liquid possesses a pungent smell of mix of vapors of chloride hydrogen and sulphurous gas. Vapors of thionyl chloride irritate mucous membranes. It is applied in a number of sintez of medicines. Water decomposes thionyl chloride to chloride hydrogen and sulphurous gas with allocation of a large number of heat.
Chloride thionyl with cold water forms sulphurous acid and hydrochloric acid, about more hotly-also sulfuric acid and sulfur.
Chloride thionyl reacts with mn. metals at ~ 100 °C with formation of chlorides, oxides, sulfides,
In prom-st thionyl chloride receive mutually S, O2 and Cl2 at 180-200 °C in prinut. active coal, it is received also r-tsiyey surplus of SO2 with CCl4 at 150 °C and pressure apprx. 4 MPas in prinut. chloride aluminum.
Chloride thionyl is applied to sulphochlorination of polymers as the chlorinating agent (e.g., in pro-publishing house of rubber, dyes, lek. sr-in), as the accelerator of polymerization of nek-ry derivatives of ethylene.
