Preparation method of dichlord isocyanurice acid

The invention discloses a preparation method of dichlord isocyanurice acid and belongs to the field of production of chemical products. The preparation method of dichlord isocyanurice acid comprises the following steps of: a chlorination step: by taking cyanuric acid and chlorine monoxide as raw materials and water as a solvent, performing a chlorination reaction to obtain a post-reaction feed liquid containing dichlord isocyanurice acid; and a post-treatment step: post-treating the post-reaction feed liquid to obtain a target product dichlord isocyanurice acid. By taking water as the solvent, the obtained product is not dissolved in water; after reaction, the operation of separating the product is simple and easy to master the technical main points; and meanwhile, mother liquor can be circularly applied without being treated, so that the preparation method is clean and pollution-free and the production cost is favorably lowered.

Mechanism of Self-decomposition of Trichloroisocyanuric Acid in Acid Medium: A Kinetic Study

Kinetics and mechanism of the self-decomposition of trichloroisocyanuric acid (TCCA) in aqueous acetic acid-perchloric acid medium has been studied in the presence as well as in the absence of Ru(III)-catalyst and chloride ion.The results show that the reaction has second order dependence on .The rate of the reaction decreases with increase in .Increase in the percentage of acetic acid decreases the rate of decomposition.Addition of chloride ion as well as Ru(III)-catalyst into the reaction mixture accelerates the rate.The reaction has been carried out at four different temperatures and net activation parameters have also been evaluated.Based on the observed data a plausible mechanism has been suggested.

A Novel Reaction of Some Enolisable Ketones not involving the Rate-determining Enolisation Step. Kinetics of the Reaction of Ketones with Trichloroisocyanuric Acid in the Presence of Added Chloride Ion in Acid Medium

Kinetics of the reaction between some enolisable ketones (S) and trichloroisocyanuric acid (TCICA) in aqueous acid-acetic acid medium at 35 deg C follow pseudo-zero-order and pseudo-first-order disappearance of 0 in the absence and the presence of added Cl-, respectively.The rate constants for the latter system exhibit a linear dependence each on 0 and +>, and an increasing and limiting dependence on added ->.The results are interpreted in terms of probable mechanisms involving (i) rate-determining enol formation from the conjugate acid of the ketone (SH+) in the absence of added Cl- and (ii) rate-determining interaction of SH+ with the most effective molecular chlorine species produced by the hydrolysis of TCICA (rather than a rate-determining interaction of enol with Cl2) in the presence of added Cl-, prior to the rapid steps of product formation.
