Epichlorohydrin, reaction with aqueous sodium

In order to continue the comparison of the aqueous sodium hydroxide dehydrochlorination with the aqueous sodium hydroxide/ sodium carbonate method the organic phase from the above reaction was removed and retreated with aqueous sodium hydroxide (a further 2 molar excess). Ultimately a 98% conversion to glycidyl 2-ethylhexanoate was achieved but by this time very extensive epichlorohydrin hydrolysis had occurred (56%). It was also found difficult to separate the organic phase from this reaction due to emulsification with the aqueous phase in order to carry out the final purification stage by distillation. 

AMMONIUM SULPHATE (7783-20-2) H8N2O4S Noncombustible solid. Aqueous solution is a strong acid. Violent reaction with fused potassium chlorate potassium nitrite. Reacts with caustics, forming ammonia. Hot material reacts with nitrates, nitrites, chlorates. Incompatible with strong oxidizers sulfuric acid aliphatic amines alkanolamines, amides, organic anhydrides isocyanates, vinyl acetate aUcylene oxides epichlorohydrin. Mixture with sodium hypochlorite forms nitrogen trichloride, an unstable explosive material. Attacks metals in the presence of moisture. 

SODIUM ALUMINATE or SODIUM ALUMINATE SOLUTION (45% or less) or SODIUM ALUMINUM OXIDE (1302-42-7 1138-49-1) AlOj Na Noncombustible solid. Aqueous solution is a strong corrosive base. Violent exothermic reaction with acids. Incompatible with aluminum, organic anhydrides acrylates, alcohols, aldehydes, alkylene oxides, substituted allyls, cellulose nitrate, chlorocarbons, copper, cresols, caprolactam solution, chlorocarbons, epichlorohydrin, ethylene dichloride, isocyanates, ketones, glycols, nitrates, phenols, phosphoms, tin, vinyl acetate, zinc. Exothermic decomposition with maleic anhydride. May increase the explosive sensitivity of nitromethane. Attacks aluminum, copper, tin, and zinc. On small fires, use dry chemical powder (such as Purple-K-Powder), sand, or COj extinguishers. Avoid the use of water or foam.
