Oxidation of organic compounds. Oxidation of starch by sodium hypochlorite, that adds carbonyl and carboxyl groups, is relevant to the production of modified starch products. In the presence of a phasetransfer catalyst, alcohols are oxidized to the corresponding carbonyl compound ( aldehyde or ketone ).Sodium hypochlorite is best stored for the longest storage life at temperatures around or below 60F (15C), when filtered and free of impurities, at dilute concentrations that maintain pH above 10, and without direct sun exposure due to the decomposition effects of ultraviolet radiation and heat. decomposition products of sodium hypochlorite

Sodium Hypochlorite or its solutions decompose when heated. Decomposition products may cause containers to rupture or explode. Vigorous reaction is possible with organic materials or oxidizing agents and may result in fire, m ay release toxic gases.

slightly acid hypochlorite solutions, and found that under these conditions the main decomposition was of hypochlorous acid molecules, by a second order reaction. It can be calculated from these results (combined with those in the present paper) that once quite a small excess of sodium How can the answer be improved?decomposition products of sodium hypochlorite Sodium Hypochlorite Bleach Decomposition Tools. The presence of these transition metal ions is known to catalyze the decomposition of liquid sodium hypochlorite, contributing to the loss of sodium hypochlorite strength and the formation of oxygen. Loss of sodium hypochlorite strength means more product will be needed when the sodium hypochlorite is used as a disinfectant.

Final Notes on Sodium Hypochlorite Stability: Sodium hypochlorite is an excellent broadspectrum sanitiser that is accepted throughout industries worldwide. Sodium hypochlorite does degrade over time. The degradation products are naturally occurring compounds. Sodium hypochlorite stability is adversely affected by increases in decomposition products of sodium hypochlorite Results are presented for the decomposition of concentrated hypochlorite ion in the pH 9 to 14 region. The combination of temperature, ionic strength, and chloride ion on the decomposition is described. TECHNICAL BULLETIN SODIUM HYPOCHLORITE DECOMPOSITION OF SODIUM HYPOCHLORITE Sodium Hypochlorite is unstable and has a limited shelf life. The chemical will decompose and the available chlorine will decrease over time. Several factors affect the rate of decomposition. The major factors 5 wt sodium hypochlorite at 25C. The pH has a significant effect on the stability of sodium hypochlorite solutions. Below pH 11 the decomposition of sodium hypochlorite is significant due to the shift in the equilibrium in favor of the more reactive hypochlorous acid. A pH between 12 and 13 gives the most stable solution. This equates to 0. 4 to Decomposition of sodium hypochlorite is increased with heavy metals such as nickel and copper in solution. There is not an easy calculation method for different levels of heavy metals except for a Powell program that is not available on the website.
