Uses and synthesis of Thionyl chloride liquid

Thionyl chloride Raw Materials (SOCl2), also known as thionyl chloride, sulfur chloride, sulfur oxide, sulfur chloride, dichlorosulfoxide, is a colorless or yellowish liquid at room temperature and pressure, with irritating odor. Relative density 1.676, melting point -104.5°C, boiling point 78.8°C. Thionyl chloride liquid is easily decomposed into sulfur dioxide and hydrogen chloride in contact with water. Soluble in benzene, chloroform and carbon tetrachloride. Decompose when heated to 150°C, decompose completely at 500°C.

Thionyl chloride liquid is sometimes confused with sulfuryl chloride (SO2Cl2), but their chemical properties are very different. Thionyl chloride CAS 7719-09-7 can react with phenol or alcohol with hydroxyl group to form the corresponding chlorides; react with Gloria reagent to form the corresponding sulfoxide compounds.

Applications / Functions of Thionyl chloride liquid

1. Thionyl chloride liquid is used in medicine, pesticide and dyestuff industries, mainly used in the production of methamidophos, methotrexate, carbofuran, anti-inflammatory pain, vitamin A and so on.
2. Thionyl chloride CAS 7719-09-7 is used as chlorinating agent for organic synthesis, such as chlorination of alcohol hydroxyl, chlorination of carboxylic acid, chlorination of acid anhydride, chlorine substitution of organic sulfonic acid or nitro compounds. Manufacture of acyl chlorides. Manufacture of pharmaceutical intermediates, such as anthelmintic, odorless synthroid. Also used as dehydrating agent and solvent.
3. Thionyl chloride Raw Materials is mainly used in the manufacture of acyl chlorides, but also used in the production of pesticides, pharmaceuticals, dyes and so on. It is produced by reacting sulfur dichloride with sulfur trioxide.

Physicochemical Property of Thionyl chloride liquid

Thionyl chloride Raw Materials is a colorless or light yellow volatile liquid with a strong asphyxiating odor. Miscible with benzene, chloroform and carbon tetrachloride.

production methodprocess of Thionyl chloride liquid

Thionyl chloride Raw Materials is produced by reacting sulfur dichloride with sulfur trioxide.

Chlorosulfonic Acid MethodFirst, sulfur powder is added into the reactor, and chlorine gas is passed to react to form sulfur monochloride. Then a certain amount of chlorosulfonic acid and sulfur monochloride added to the reactor, at 50 ℃ below the passage of chlorine gas for the reaction, the reaction of the material through the crude distillation, condensation, collection of 130 ℃ below the material sent to the distillation pot, in order to make the low-boiling point of sulfur dichloride into sulfur monochloride to stay in the pot, it is necessary to add a crude amount of 15% to 20% of the sulfur yellow, and then sent to the distillation, after reflux 4h, the color and lustre of the normal, collect the Gas phase 75 ~ 80 ℃ fraction, to produce Thionyl chloride liquid.

Its 2ClSO3H+S2C12+C12→2SOC12+2SO2+2HCl Sulfur dioxide method to sulfur yellow, liquid chlorine and liquid sulfur dioxide as raw materials, the use of full-cycle and liquid-phase recycling method, the production of high-purity sulfoxide alumina, the purity of 99% or more, the method of advanced technology, product quality and stability, the "three wastes The process is advanced, the product quality is stable, and the emission of "three wastes" is less.
