METHOD FOR PRODUCTION OF SODIUM PERBORATE |
| 摘要 |
FIELD: chemical industry, namely, production of sodium perborate. SUBSTANCE: origin material is decomposed with reusable mother solution being prepared after crystallization of final product. Boron-containing ore, namely, tincal mineral is used as said origin material. Mineral is fed into reusable solution, rate of its feeding is 30-125 kg of B<SB>2</SB>O<SB>3</SB>/h per 1 m of solution. Thus prepared solution of sodium metaborate is separated of slime and cooled. The process is followed by treatment with 27-40 % solution of hydrogen peroxide and by crystallization. EFFECT: improved efficiency of the method. 2 clr
