Sodium dichloroisocyanurate synthesis

1synthesis methods
Sodium dichloroisocyanurate is produced by chlorination of disodium cyanurate [Na2H(NCO)3] using chlorine (CI2) and neutralization with sodium hydroxide (NaOH).
Disodium cyanurate is obtained by action of sodium hydroxide on isocyanuric acid.

21 Generation of Sodium Dichloroisocyanurate in Reaction System

A glass-made reaction container was charged with 3.07 g of isocyanuric acid (trade name: CA-P, available from Nissan Chemical Corporation) and 35.90 g of aqueous sodium hypochlorite solution (Cica first grade, available from KANTO CHEMICAL CO., INC.,), and the resultant mixture was stirred at 40° C. for homogeneous dissolution, to thereby generate sodium dichloroisocyanurate in the reaction system. Thereafter, the resultant solution was cooled to 20° C., and 6.00 g of dimethyl sulfate (available from Tokyo Chemical Industry Co., Ltd.) was added dropwise to the solution. The resultant mixture was stirred at 20° C. for six hours.
