摘要: PROCESS FOR THE MANUFACTURE OF POLYGLYCIDYL ETHERS BY CONDENSATION OF ALIPHATIC OR CYCLOALIPHATIC POLYHYDROXY COMPOUNDS WHICH HAVE A MELTING POINT OF AT LEAST 80*C., FOR EXAMPLE PENTAERYTHRITOL, DIPENTAERYTHRITOL, SORBITOL, 2,2-BIS-(P-HYDROXYCYCLOHEXYL)-PROPANE OR 1,12-DIHYDROXYDODECANE, WITH AN EPIHALOGENOHYDRIN OR B-METHYLEPHIHALOGENOHYDRIN, FOR EXAMPLE EPICHLOHYDRIN, IN A FIRST STAGE IN THE PRESENCE OF A SOLVENT WHICH CONSISTS OF 100-30 PRECENT BY WEIGHT OF 1,4-DIOXAN AND 0-70 PERCENT BY WEIGHT OF ANOTHER ORGANIC SOLVENT WHICH HAS A BOILING POINT OF AT LEAST 70*C. AND IS NOT REACTIVE TOWARDS AN EPITHALOGENOHYDRIN, TO GIVE THE CORRESPONDING CHLORHYDRIN ETHERS AND, IN A SECOND STAGE, WITH AGENTS WHICH SPLIT OFF HYDROGEN HALIDE, TO GIVE THE CORRESPONDING POLYGLYCIDYL ETHERS.
