| titleOfInvention | A kind of method for comprehensive utilization of diethyl methyl phosphite rectification still residue |
| abstract | The invention belongs to the technical field of waste treatment generated in the chemical production process, and particularly relates to a method for comprehensive utilization of diethyl methylphosphonite rectification still residues. The specific steps of the method are: performing vacuum distillation on the rectification still residue generated in the process of preparing diethyl methyl phosphinate to obtain light components, and the light components include diethyl methyl phosphinate , monoethyl methyl phosphinate, triethyl phosphinate and diethyl methyl phosphate; add a double bond compound to the light component, stir to carry out an addition reaction, and after the reaction finishes, obtain a mixture; The mixed material is rectified, and the temperature and vacuum degree of the rectification are controlled to obtain triethyl phosphite, diethyl methyl phosphonate and addition product respectively. The method provided by the invention has simple process operation, and can fully utilize the liquid still residue to produce high value-added products, so that this part of the liquid hazardous waste can be reasonably utilized, and the economic benefit of the enterprise is increased. |
