Uses and synthesis of p-toluene sulfonyl chloride Powder

p-toluene sulfonyl chloride Powder, as a fine chemical product, is widely used in dyestuff, pharmaceutical and pesticide industries. In dyestuff industry, it is mainly used in the manufacture of intermediates of disperse, ice-dye and acid dyestuff; p-toluene sulfonyl chloride CAS 98-59-9 is mainly used in the production of sulfanilamide, metsulfometuron and so on in the pharmaceutical industry; and it is mainly used in the pesticide industry for the production of metsulfometuron, sulfoxaflor, spermaceti, and so on. With the continuous development of dyestuff, pharmaceutical and pesticide industries, the demand for p-toluene sulfonyl chloride Powder is growing internationally, especially in Europe and America, and the market is promising.

p-toluene sulfonyl chloride CAS 98-59-9, Chinese alias 4-methylbenzenesulfonyl chloride, p-toluene sulfonyl chloride (PTSC), p-toluene sulfonyl chloride, 4-toluene sulfonyl chloride, toluene-4-sulfonyl chloride. p-toluene sulfonyl chloride Powder is a white flaky crystal. Soluble in alcohol, ether and benzene, insoluble in water.

Applications / Functions of p-toluene sulfonyl chloride Powder

1. p-toluene sulfonyl chloride Raw Materials are white flaky crystals with melting point 69-71°C. It is an important intermediate for organic synthesis of drugs, mainly used in the synthesis of aminosulfonyl chloramphenicol, chloramphenicol-T, sulfonylmethoxymethyl and other drugs.
2. p-toluene sulfonyl chloride Powder is the intermediate of disperse dye, ice dye and acid dye. It is also used in the production of the drug Methylsulfonylmethane.
3. p-toluene sulfonyl chloride CAS 98-59-9 is used as analytical reagent, also used in organic synthesis, dye preparation and hormone synthesis in molecular rearrangement reaction.
4. p-toluene sulfonyl chloride Raw Materials is used in organic synthesis, sulfonamide and pesticide intermediates.

Physicochemical Property of p-toluene sulfonyl chloride Powder

p-toluene sulfonyl chloride Powder White flaky crystals. Melting point 71℃. Boiling point 151.6℃(1.67kPa), 145-146℃(2.0kPa). Soluble in alcohol, ether and benzene, insoluble in water.

production methodprocess of p-toluene sulfonyl chloride Powder

In the production of o-toluene sulfonyl chloride by toluene chlorosulfonation, p-toluene sulfonyl chloride Powder is also generated. p-toluene sulfonyl chloride Raw Materials are obtained by refining from the filter cake after separating o-toluene sulfonyl chloride.

1. Toluene Sulfonation Method Toluene reacts with chlorosulfonic acid, and the reaction product is distilled under reduced pressure or freeze crystallized to obtain p-toluene sulfonyl chloride CAS 98-59-9.
2. Folding toluene sulfonyl chloride method Toluene is reacted with concentrated sulfuric acid and then chlorinated with dichlorosulfoxide, the reaction product is distilled under reduced pressure to obtain p-toluene sulfonyl chloride CAS 98-59-9.
