Title:
PROCESS FOR PREPARING STABILIZED ADDUCT OF SODIUM SULPHATE-HYDROGEN PEROXIDE-SODIUM CHLORIDE
Document Type and Number:
Japanese Patent JPS6051611
Kind Code:
A
Abstract:
PURPOSE: To prepare the titled adduct having excellent storage stability by incorporating a phosphoric acid compd. thereto.
CONSTITUTION: A phosphoric acid compd. selected from ortho phosphoric acid, condensed phosphoric acid, and their salts is used. Namely, sodium sulphate, hydrogen peroxide, and a phosphorus compd. are added to mother liquid contg. ≥0.3mol/l H2O2, ≥0.1mol/l SO4--, ≥0.2mol/l Cl-, and ≥1.5mol/l Na+ causing a reaction at ≤ca. 9pH, ca. 0W60°C while stirring, and formed crystals are collected. Thus, adduct of Na2SO4-H2O2-NaCl (4Na2SO4.2H2O2. NaCl) containg 0.005W2wt% (expressed in terms of P) P compd. is obtd.
