Study on recovery and refining technique of n-butanol produced by 1,4-butanediol production devise

The mainly impurities of the n-butanol solution produced by 1,4-butanediol production devise of Daqing Oil Field Chemical Industry Ltd. are methanol, tetrahydrofuran, methoxymethane and water, by the thermo-dynamic analyses and computations of the n-butanol solution,we can separate them by rectification.The whole recycling process is simulated by software,we can get n-butanol with the purity of 99.99% and methanol with the purity of 98.965%.
