A kind of recycling method of diethyl maleate tail material |
| abstract |
The invention discloses a method for recycling diethyl maleate tailings, and belongs to the technical field of diethyl maleate. The recycling method comprises the following steps: performing vacuum distillation on the tailings of diethyl maleate to be treated to obtain a mixture containing the first component and the second component; the first component is an organic compound that can be mixed with primary amines Organic matter for addition reaction, the second component is organic matter that cannot undergo addition reaction with primary amine organic matter; the first component contains diethyl maleate and diethyl fumarate; the mixture is mixed with primary amine organic matter , so that the first component in the mixture undergoes addition reaction with primary amine organic matter to obtain polyaspartate resin. The above method can fully recycle the by-products produced in the production process of diethyl maleate, and has certain economic benefits while reducing carbon emissions. |
