Title:
PURIFICATION OF ETHYLTETRAHYDROFURFURYL ETHER BY BRINE SOLUTION EXTRACTION
Document Type and Number:
Japanese Patent JPS57139072
Kind Code:
A
Abstract:
Mixtures including ethyl tetrahydrofurfuryl ether (ETFE), tetrahydrofurfuryl alcohol (THFA), ethanol and water, and usually also an ethyl halide, are extracted with an aqueous solution of an alkali metal or alkaline earth metal chloride salt until THFA/ETFE ratios below 0.01 or 0.001 are achieved. Thereby THFA and ethanol, each of which are difficult to separate from ETFE by distillation, are removed.
