Abstract
The polyvalent phenol is >=60% catalytically etherified (calc. on the no. of phenolic OH gps.) with 3-8 equiv. epihalohydrin per phenolic OH gp, and the mixture obtained is treated with org. alkali contg. 0.5-0.98 equiv. alkali cpd. per phenolic OH gp and of concn. which is not > than the saturation concn. of the salt produced by this alkali treatment at the temp. of the reaction mixture. In this process (a) the alkali treatment is effected at >=50 degrees C, the aqs. phase being separated, the epihalohydrin being distilled from the organic phase and the residue being post. treated with the aq. alkali, or (b) all or some of the epihalohydrin is distilled from the etherification mixture and the residue is treated with the aq alkali at >=50 degrees C, the aq. phase being separated and residual epihalohydrin from both the organic phase and from the prior alkali treatment distilled, and the residue being treated as in (a). Loss of epihalodrin is minimal, quality of opoxy resin produced from the polyglycidyl ethers is not reduced and no blockage of the tubes and pipes in the plant by pptd. salt, nor overheating occurs.
