| titleOfInvention | A method for controlling organic amines in waste brine prepared from MDA formation |
| abstract | The invention provides a method for controlling organic amines in waste brine prepared from MDA. The method aims at the problem that during the MDA preparation process, especially under the process condition of high formaldehyde ratio, the organic amine content in the formed waste brine is relatively high, and cannot be directly discharged into the sea or reused in the chlor-alkali industry. The present invention controls 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 of aniline salt and formaldehyde, and preferably through the condensation reaction according to the main source of turbidity The content of macromolecular polyamines in the liquid can adjust the turbidity. The method of the invention is intuitive and convenient, the result is accurate, and the control means is convenient for industrialized implementation. |
