| titleOfInvention | Method of synthesising 1,6-hexamethylenediamine- n, n'-disuccinic acid |
| abstract | FIELD: chemistry. n SUBSTANCE: method includes preparation of reaction solution by dissolving maleic anhydride in water, addition of solutions of alkaline reagent, representing lithium hydroxide, and 1,6-hexanediamine, boiling solution, bringing solution pH to 2.6 by means of concentrated solution of hydrobromic acid, product crystallisation, separation of crystals from solution, and purification of product from inorganic substances - by-products of reactions that take place on solution. Purification of final product from lithium bromide is carried out in one stage by means of hot acetone. n EFFECT: method makes it possible to obtain product of higher purity without loss of output. n 1 tbl, 1 ex |
