| titleOfInvention |
Process for the continuous preparation of polyglycidyl ethers of polyhydroxy phenols |
| abstract |
Liquid epoxy resins are produced by contacting a dihydroxy phenol with an excess of epihalohydrin and an aqueous solution of an alkali metal hydroxide in a molar ratio of hydroxide to phenol not exceeding 2:1, recovering from the reaction products an epoxy resin having a content of hydrolyzable chlorine of from 1 to 6% by weight, contacting a solution of the resin in a hydrocarbon with an aqueous solution of an alkali metal hydroxide while maintaining an atomic ratio of alkali metal to hydrolyzable chlorine contained in the resin of from 1:1 to 1.17:1 and recovering from the reaction products a liquid epoxy resin having a content of hydrolyzable chlorine less than 0.02% by weight. |
