✦ Synopsis

of pure isopropyl ether at 630 mm Hg (84 kPa); and the acetone goes to the stillpot with the extractive distillation agent. The designation R by the extractive distillation agent means that the same material was recovered and reused to show its stability in repeated operation. When the acetone-extractive distillation agent mixture taken from the stillpot is redistilled, acetone comes off in the usual way at its normal boiling point, 56°C.

The results obtained in the rectification column and presented in Table show that vapor-liquid equilibrium data obtained in the Othmer still can be successfully used to demonstrate the effectiveness of extractive distillation in the separation of pure isopropyl ether from acetone.
