| titleOfInvention | Production system of p-aminobenzoyl glutamic acid |
| abstract | The utility model discloses a production system of p-aminobenzoyl glutamic acid, including condensation reation kettle, liquid caustic soda dropwise add jar, paranitrobenzoyl chloride dropwise add jar, hydrogenation reation kettle, filter, crystallization kettle, hydrochloric acid dropwise add jar and centrifuge. An alkali flow automatic regulating valve is arranged between a liquid alkali dropping port of the condensation reaction kettle and a second discharge port of the liquid alkali dropping tank; and a signal input port of the alkali flow automatic regulating valve is connected with a first pH value test port of the condensation reaction kettle. An acid flow automatic regulating valve is arranged between the hydrochloric acid dripping port of the crystallization kettle and the seventh discharge port of the hydrochloric acid dripping tank; and a signal input port of the acid flow automatic regulating valve is connected with a second acid alkalinity testing port of the crystallization kettle. The utility model discloses a high accuracy control of material pH nature in the p-aminobenzoyl glutamic acid production process has improved the stability and the product quality of technology, has reduced intensity of labour, has reduced environmental pollution, has effectively guaranteed production safety, has improved the market competition of product. |
