Title:
CRYSTALLINE FORM OF SODIUM HYPOCHLORITE PENTAHYDRATE AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2018/159233
Kind Code:
A1
Abstract:
Provided are: a crystalline form of sodium hypochlorite pentahydrate which can be stored for a long period of time, wherein the stability of sodium hypochlorite pentahydrate which is effective as an oxidant or a disinfectant has been improved; and a method for producing the same. The crystalline form of sodium hypochlorite pentahydrate has a peak at a position of an angle of diffraction indicated in Table 1 of claim 1 in a range of 10°≤2θ(angle of diffraction)≤65° by powder X-ray diffraction measurements using a CuKα radiation source.
