47、m dichloroisocyanurate, anhydrous is manufactured from isocyanuric acid (CNOH)3, sodium hydroxide (NaOH) and chlorine (Cl2). A.1.2 Manufacturing process Sodium dichloroisocyanurate, anhydrous is produced by chlorination of disodium cyanurate (Na2H(NCO)3) using chlorine (Cl2) and neutralisation with
48、sodium hydroxide (NaOH). Disodium cyanurate is obtained by action of sodium hydroxide on isocyanuric acid. A.2 Use A.2.1 Function The product is used as a disinfectant of swimming pool water. It is an indirect source of free chlorine (HOCl) when dissolved in water via an organic carrier substance (sodium cyanurate, C3N3O3H2Na): C3N3O3Cl2Na + 2H2O - C3N3O3H2Na + 2HOCl (A.1) As the disinfectant (HOCl) is used up, more chlorine atoms are released from “sodium dichloroisocyanurate, anhydrou
