| titleOfInvention | A kind of control method of organic amine in waste brine formed by preparing MDA |
| abstract | The invention provides a method for controlling organic amines in waste brine formed by preparing MDA. The method is aimed at the problem that the organic amine content in the formed waste brine is high in the MDA preparation process, especially under the high formaldehyde ratio process conditions, and cannot be directly discharged into the sea or reused in the chlor-alkali industry. The present invention controls from the source of organic amine formation, and controls the organic amine in the final waste brine by controlling the turbidity of the reaction solution after the condensation reaction between aniline salt and formaldehyde, and preferably through the condensation reaction according to the main source of turbidity The content of macromolecular polyamine in the liquid adjusts the turbidity. The method of the invention is intuitive and convenient, the result is accurate, and the control means is convenient for industrialized implementation. |
