| titleOfInvention | One recycles waste water and prepares N, N ' production method of-dicyclohexylcarbodiimide |
| abstract | Disclosure one recycles waste water and prepares N, N ' production method of-dicyclohexylcarbodiimide, organic compound synthesis technical field.Solve the reluctant problem of existing saline sewage.By N, the N that N '-dicyclohexylcarbodiimide produces after using, N-1,3-Dicyclohexylurea first washes removal impurity, then react with oxidant in organic solvent, reactant liquor is added drop-wise in aqueous alkali and is neutralized reaction, neutralization reaction product is stratification after filtering, and organic layer separated obtains DCC product, the solvent direct reuse steamed；Water layer filters out after inorganic salt as the Water circulation needed for configuration alkali liquor.The DCU that this production method produces after being used by DCC reuses acquisition DCC, and the brine waste simultaneously produced recycles, and decreases the discharge of saline sewage and greatly reduces saline sewage process. |
