| titleOfInvention | The method of dimethyl malonate production wastewater treatment and resource reclaim |
| abstract | Disclosed by the invention is the method for dimethyl malonate production wastewater treatment and resource reclaim, and its step is that methyl alcohol, ammonia neutralization and condensing crystal reclaim(ed) sulfuric acid ammonium are reclaimed in rectifying, or methyl alcohol and condensing crystal reclaim(ed) sulfuric acid ammonium are reclaimed in ammonia neutralization, rectifying; The rate of recovery of single batch of methyl alcohol of the present invention is greater than 85%, the methyl alcohol reclaimed can be applied mechanically in dimethyl malonate is produced, the rate of recovery of single batch of ammonium sulfate is greater than 70%, can be used as byproduct to sell, the raffinate reclaimed after methyl alcohol and ammonium sulfate can continue to apply mechanically in the malonic acid dimethyl ester production process extraction phase-splitting stage; After method process of the present invention, dimethyl malonate produce without high-concentration wastewater emission, useful resources is utilized effectively, and reduces environmental protection pressure and production cost, economy and environment protecting obvious. |
