Abstract: THE PRESENT INVENTION PROVIDES A PROCESS FOR DISTILLATIVELY PURIFYING CRUDE WATER-CONTAINING TETRAHYDROFURAN BY PASSING THE CRUDE TETRAHYDROFURAN THROUGH THREE DISTILLATION COLUMNS, WITHDRAWING WATER FROM THE BOTTOM OF THE FIRST COLUMN, RECYCLING WATER—CONTAINING TETRAHYDROFURAN FROM THE TOP OF THE SECOND COLUMN INTO THE FIRST COLUMN, PASSING A SIDESTREAM OF THE FIRST COLUMN INTO THE SECOND COLUMN, RECYCLING THE BOTTOM PRODUCT OF THE THIRD COLUMN INTO THE FIRST COLU.MN AND WITHDRAWING A DISTILLATE AT THE TOP OF THE FIRST COLUMN, WHICH COMPRISES PASSING A SIDESTREAM OF THE SECOND- COLUMN INTO THE THIRD COLUMN AND RECOVERING THE PURE TETRAHYDROFURAN AS THE TOP PRODUCT OF THE THIRD COLUMN.
