Trichloroisocyanuric acid (TCCA) as accelerators, sulfur, phenol and a phosphite was synthesized a series of phosphorothioate

Trichloroisocyanuric acid (TCCA) as accelerators, sulfur, phenol and a phosphite was synthesized a series of phosphorothioate, with 1H NMR, 13C NMR and mass spectrometry to characterize the structure of the product compared with traditional methods, the method is fast, efficient, mild reaction condition and substrate compatibility, and provide a new approach for the synthesis of phosphorothioate.
Trichloroisocyanuric acid (TCCA) (referred to trichloromethyl) and cyanuric acid trisodium salt under certain conditions, can react sodium dichloroisocyanurate (short-dichloro). Supplying gas production using chlorine disinfectant of new technology to solve the poor quality of the original dichloro-production process, dichloroisocyanurate isolated after chlorination with sodium carbonate or caustic and dissolved, frozen, crystallization and other batch jobs the problem, enabling continuous operation, easy operation, safe and reliable; dichloro liquor in addition to direct return preparation trichloro suspension, the remaining mother liquor feed dichloro-trichloro means chloride recovered trichloride, which produces liquor triclosan trichloro liquor processing means for generating along evacuation of chlor-alkali plants using salt to achieve zero discharge of wastewater.
The present review summarizes the synthetic application of trichloroisocyanuric acid (TCCA) [1,3,5-trichloro-1,3,5-triazine-2,4,6- (1H,3H,5H)-trione] as a convenient reagent for the electrophilic chlorination of unsaturated carbon-carbon bonds and focuses on its green aspects. Chlorination reactions involving alkenes, alkynes, arenes, and (di)carbonyl compounds and the chlorodecarboxylation of cinnamic acids (Hunsdiecker reaction) are presented and discussed. Trichloroisocyanuric acid is a safe, stable, easily handled, inexpensive and commercially available solid. At the end of the reactions, cyanuric acid is obtained as by-product and can be reused to produce trichloroisocyanuric acid. In accordance with green chemistry principles, the use of trichloroisocyanuric acid enables chlorination without chlorine or other harmful or dangerous reagents.
