| titleOfInvention | A kind of new technology of separation water-methyl hydrazine azeotropic mixture |
| abstract | The invention discloses a kind of continuous extraction distillation and separation method of water-methyl hydrazine azeotropic mixture.The method using the mixture of acetonitrile and MEK as extractant, using the method for continuous extraction rectifying come separation water-methyl hydrazine azeotropic mixture, the operating condition of extractive distillation column：Extractant is 1 ~ 10 with the mass ratio of charging:1, continuous extraction rectifying tower and solvent recovery column overhead different temperatures and different reflux ratios are controlled, by extractive distillation column overhead extraction methyl hydrazine, solvent recovery tower bottom of towe recovered water, the extractant of bottom of towe is entered into extractive distillation column and recycled.The advantage of the invention is that destroying water-methyl hydrazine azeotropic system using new extractant, high purity water, methyl hydrazine product are isolated.Continuous rectification efficiency high, yield is big, and solvent recovery is simple. |
