Process for reducing the content of hydrolysable chlorine in glycidyl compounds Abstract To reduce the content of hydrolysable chlorine in glycidyl compounds, these are dissolved in a halogen-free organic solvent and treated with an equivalent excess of aqueous alkali metal hydroxide solution at elevated tem- perature, the excess being 100 to 200%; of the equivalent amount theoretically required for complete dehydrochlorina- tion of the hydrolysable chlorine, the water is then removed from the organic solution, the organic solution is treated with 5 to 500 times the amount, based on the amount of alkali metal hydroxide employed, of moist cellulose containing up to 35% by weight of water at elevated temperature and, after filtration, the glycidyl compound is isolated from the organic solution.
