Chemical Intermediate Thionyl Chloride CAS 7719-09-7
Thionyl Chloride, also known as thionyl chloride, sulfur oxychloride, sulfur oxychloride, dichlorosulfoxide, at room temperature and atmospheric pressure for colorless or light yellow liquid, has a pungent odor. The relative density is 1.676, melting point is -104.5, and boiling point is 78.8. Water is readily decomposed into sulfur dioxide and hydrogen chloride. Soluble in benzene, chloroform and carbon tetrachloride. Heating to 150 degrees C begins to decompose and decomposes completely at 500 degree C. Chlorinated sulfoxide is sometimes confused with sulfuryl chloride (SO2Cl2), but their chemical properties are very different. Its chlorine atoms are capable of replacing hydroxyl or sulfur groups. Sulfoxide chloride reacts with hydroxyl phenols or alcohols to form corresponding chlorides, and with Grignard reagents to form corresponding sulfoxide compounds. The molecular configuration of sulfoxide is cone type, where the sulfur (VI) center contains a pair of lone pair electrons. COCl2 is a planar configuration. Because chlorinated sulfoxide is strongly reactive with water, SOCl2 does not exist in nature.

Thionyl chloride Application:
Sulfoxide chloride is an important organic chemical intermediate, mainly used in medicine, pesticide, dyestuff industry and organic synthesis industry, as chlorinating agent. The consumption structure is as follows: 25% in the pharmaceutical industry, 50% in the pesticide industry, 5% in the dyestuff industry, 20% in the other industries. The pesticide industry is the most important consumption field of sulfoxide chloride in China. It is mainly used to produce loxamine, fenvalerate, fenvalerate, fenvalerate, fenvalerate, fenvalerate, fenvalerate, fenvalerate, juvenile urea, thiophosphate, fenvalerate, Fen Endosulfan, deltamethrin, methyl (ethyl) chlorpyrifos, azolazone, quetiapine and rodenticide.
