STABILIZED ALKALI METAL PEROXYSALT AND PROCESS FOR PRODUCTION THEREOF

摘要

A process for stabilizing particulate alkali metal peroxy salts by coating with a solid coating material and the resulting particulate alkali metal peroxy salts which are stabilized by coating. The coating material is a crystallized mineral salt mixture of alkali metal sulfate and alkali metal chloride which optionally may additionally contain alkali metal silicate. Particularly suitable alkali metal peroxy salts include peroxypyrophosphate, peroxytripolyphosphate, peroxymonosulfate and peroxycarbonate.
