Description

Quantitative feeding mechanism for iminodiacetic acid Technical Field The utility model relates to the technical field of iminodiacetic acid production, in particular to a quantitative feeding mechanism for iminodiacetic acid. Background Iminodiacetic acid (IDA) is an important organic compound, and amino and carboxyl functional groups contained in the molecular structure of the iminodiacetic acid (IDA) endow the iminodiacetic acid with the characteristic of generating corresponding salts by reacting with acid and alkali, and can form stable chelates with various metal ions. In the field of pesticide synthesis, the compound is a key intermediate for preparing a broad-spectrum herbicide glyphosate, the accurate control of the content of the compound directly relates to the yield and purity of the glyphosate synthesis, and in the production process, if the IDA content in the raw materials is improperly controlled, the yield is not only affected fully by the glyphosate synthesis reaction, but also the quality of the product is unqualified possibly caused by the residue of the raw materials or the exceeding of impurities, and the adverse effect is brought to the subsequent product detection and market application.
