ABSTRACT:
Sodium Chlorite is made stable under storage conditions by (1) admixing with the sodium chlorite a stabilizing salt chemically inert to sodium chlorite and having at least one hydrate whose melting point is higher than about 50.degree. C, in amount such that said stabilizing salt can capture a quantity of water equal to at least about 5% of the weight of the sodium chlorite (NaClO.sub.2), the weight of the water in the total mixture being at least about 5% of the weight of said sodium chlorite and (2) drying the mixture sufficiently to reduce the water not captured by the stabilizing salt to an amount equal approximately to zero. Sodium chlorite thus stabilized is thermally stable and does not congeal into a solid mass even when stored in drums for several months at 50.degree. C.
