| titleOfInvention | A kind of method of rectified purified dimethyl succinate |
| abstract | The invention discloses a kind of method of rectified purified dimethyl succinate, by the dimethyl succinate crude product of high temperature successively through treating tower feed preheater, lightness-removing column feed preheater and vapour generator, reclaim the heat in crude product respectively, crude product cools laggard row gas-liquid separation by wet air cooler again, obtains liquid phase material; Liquid phase material is sent into described lightness-removing column feed preheater to heat, then enter lightness-removing column and process, obtain the bottom product of lightness-removing column; Bottom product is sent into described treating tower feed preheater to heat, then enter treating tower and carry out refinement treatment, obtain from the tower top of described treating tower the dimethyl succinate that purity is more than 99.8%, product exports after the cooling of product air cooler.This law can obtain the dimethyl succinate of purity 99.9% from low levels dimethyl succinate crude product, and has that product recovery rate is high, heat effectively utilizes and be easy to industrialized advantage. |
