| Abstract: | The gas liquid equilibrium data of 2 methylbutanol and 3 methylbutanol and practical plate number 230(theoretical plate number=150) for separation were obtained experimentally.Also,problems of distribution of refluxing,series connection of fractionating column and liquid level controlling were solved for realization of continuous separation of difficult system.2 Methylbutanol and 3 methylbutanol of more than 99% purity were obtained in over 98% yield,in comparison with the literature data of 95%purity and 30% yield. |
