| titleOfInvention | A kind of separation method of the close polyol blends of boiling point |
| abstract | The invention discloses a kind of separation methods of the close polyol blends of boiling point, using the ethylene glycol containing binary or polynary fusel as raw material, under the action of acid catalyst, binary or polynary fusel pass through (1) dehydration (2) pinacol rearrangement (3) acetal or ketal reaction, acetal, ketal (few) are generated, and passes through distillation and collects；Meanwhile reaction solution obtains high-purity ethylene glycol by further separation.The present invention provides a kind of reacted by liquid-phase dehydration to remove the route of binary or polynary fusel in ethylene glycol, reaction condition is mild, particularly to being difficult to remove 1 with conventional means, 2 butanediols have higher removal efficiency, finally obtain the very high ethylene glycol product of purity；By-product added value higher acetals or ketal compounds simultaneously, also can the basic chemical industries raw material such as the certain acetaldehyde of output, propionic aldehyde and acetone.The present invention is that the ethylene glycol crude product for being difficult to detach is converted into high-purity ethylene glycol and the environmentally protective technique of other chemical products. |
