It contains two crystal waters. When dried, it easily loses crystal water. It is easily soluble in water. The PH value of 5% water solution is 4-6. it is hardly soluble in organic solvents like alcohol or ethyl ether. Exterior White powder Content ≥ % 99.0 Reaction of water solution pass Complexation test pass Clarification test pass Fe%≤ 0.005 Heavy metal pb%≤ 0.005 Sulfate % (SO4) ≤ 0.1 Cl%≤ 0.01 MAIN APPLICATION: Disodium salt is used in detergent, liquid soap, shampoo, agricultural chemicals, fixer solution for development of colour film, water cleaner, PH modifier. When stating the redox reaction for the polymerization of butyl benzene rubber, it is used as part of activator for the compellation of ferro ion and control of polymerization speed.
