About TCCA Disinfectant Chlorination Mechanism

Chlorine-containing organic compounds are widely used in the synthesis of various compounds such as medicines, pesticides, and materials. They are an important class of organic synthesis intermediates and have good development prospects. Trichloroisocyanuric acid disinfectant is a chlorinated isocyanuric acid, one of the cyanuric acid products, referred to TCCA disinfectant, is a white powdery solid with a strong irritating smell of chlorine.

Functions And Uses of TCCA Disinfectant

TCCA Disinfectant is a very strong chlorinating reagent and oxidant, with an effective chlorine content of more than 90%. TCCA also has strong bleaching and bactericidal effects, and is widely used in civil sanitation and animal husbandry as a high-efficiency sterilization and disinfectant. It can also be used in rubber chlorination, battery materials and organic synthesis industries. In the beginning, TCCA was used as an oxidant to participate in various organic synthesis reactions.

Know about the chlorination mechanism of TCCA Disinfectant

Chlorination reaction with aliphatic hydrocarbons

Trichloroisocyanuric acid can not only be monochlorinated with the benzyl side chain, but also can form a dichlorinated product at the same site of the benzyl side chain, and even chlorine can attack the benzene ring to form various substituted chlorobenzenes. It is worth noting that when a catalytic amount of CBr4 is used in the reaction, the reaction time is greatly shortened.

Chlorination reaction with olefins

Through the reaction of olefin and trichloroisocyanuric acid in alcohol, different α-chloroethyl ether, α-chloroacetate and chlorohydrin were effectively obtained, and the yield was up to 96%. Compared with the earlier traditional methods of synthesizing these compounds from olefins, this method is simpler and more efficient.

Chlorination reaction with aromatic hydrocarbons

In some experiments, various substituted benzenes were used as substrates to realize the chlorination of various substituted benzenes by TCCA, forming chlorobenzenes substituted by chlorine at different positions. When trichloroisocyanuric acid reacts with aromatic hydrocarbons, its yield is greatly affected by the strength of the acid in the system. In H2SO4, the deactivated aromatics are effectively chlorinated by TCCA.

Chlorination reaction with alcohol

Using TCCA as a chlorinating reagent under heating conditions can realize the reaction of converting alcohols into chlorinated hydrocarbons. TCCA is used as oxidant and chlorinating reagent to realize the oxidation reaction of alcohol to ketone under metal-free conditions. Under reducing conditions, monochlorinated acetone may also be converted to chlorohydrin. The process uses the characteristics of TCCA oxidation and chlorination to successfully chlorinate enol to obtain a chloroketone.

Using TCCA as oxidant and chlorinating reagent, a new type of metal-free alcohol oxidation cross-esterification reaction was realized. Alcohol is converted into the corresponding acid chloride in situ, and then reacted with aliphatic long-chain primary alcohol, benzyl alcohol, allyl alcohol and phenols. The reaction obtained various esters in high yields. This method uses inexpensive and readily available reagents under mild reaction conditions. It is worth noting that the formation of self-coupling products was not observed in this reaction study.

Chlorination reaction with aldehyde

Effective oxidative esterification was carried out under mild conditions, and aromatic and aliphatic aldehydes were simply converted into esters. In this process, the aldehyde is converted into the corresponding acid chloride in situ, and then reacted with chain aliphatic alcohols, benzyl alcohol, allyl alcohol and propargyl alcohol and phenols to obtain a variety of esters in high yield.

Chlorination reaction with ketone

Tribromoisocyanuric acid (TBCA) and trichloroisocyanuric acid (TCCA) can directly halogenate electron-rich aryl ketones without solvent and under grinding conditions. The process is simple to operate, the reaction takes place within a few hours, and the desired halogenated product can be efficiently obtained.

Chlorination reaction with phosphorus atom

TCCA was first used in this reaction as a chlorinating reagent for polyalkylene phosphonates. Polyoxyethylene H-phthalate and TCCA can quantitatively obtain polyoxyethylene oxyethylene within 1 hour at room temperature. Polyalkylene chlorophosphate has been used as an effective polymer carrier for low-molecular bioactive substances carrying hydroxyl or amino groups. The different molar ratios of trichloroisocyanuric acid and polyalkylene H-phthalate can control the degree of chlorination and obtain copolyphosphate with new properties.
