Abstract

PURPOSE: To preparetetrahydrofuran in high purity, by distilling a mixture of tetrahydrofuran and ethanol under a reduced pressure of ≤ 1 kg/cm2, and distilling the above distillate consisting of contrated tetrahydrofuran solution under normal or positive pressure, thereby remaining the pure tetrahydrofuran as distillation residue.
