    摘要： A vertical reactor system having a plurality of substantially vertically aligned reaction compartments one on top of the other, the reactant materials (and catalyst and solvent, if desired), flowable from a first top compartment through intermediate compartments, if any, to a bottom compartment from which a desired product of a reaction of the reactant materials is withdrawn, the compartments having inlets for the addition of additional reactants, catalysts, or solvents and outlets for withdrawing by-products, vapors, and water from any compartment, and processes for producing products using such a system. In one embodiment the product is a liquid epoxy resin. Stirring impellers may be provided in any compartment. A liquid seal may be provided on a shaft for the impellers and, in one embodiment the seals in each compartment may be elevated above the liquid in the compartments.

    摘要： Epichlorohydrin levels in heat sensitive glycidyl products are reduced from a few thousand ppm, an unacceptable level, to only a few ppm or to a non-detectable level by use of a multistage stripping column with or without inert gas purging without decomposition of the heat sensitive glycidyl products. Such glycidyl products are useful in epoxy resins particularly as crosslinking agents.

    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.
