Synthesis method

Add 600 g (3.64 mol) of 1.2-chloroquinoline, 688 g (4.00 mol) of sulfonamide, and 800 g K2CO3 into a 2500 mL four-neck flask, heat, react for 3 hours, add water and boil for 5 min, cool, filter, and obtain the filtrate Carefully acidify with dilute hydrochloric acid to pH=5.5, cool and filter, and dry the filtrate to obtain 1050 g of light yellow powdery solid, which is the product. The yield is 98% and the purity is 98.5%.

2.Using o-phenylenediamine as raw material, it first reacts with sodium cyanide and formaldehyde in an acidic medium, and then undergoes cyclization and oxidative dehydrogenation. , and finally condensed and hydrolyzed to obtain the product. Products can also be made from the reaction of o-phenylenediamine and chloroacetic acid, followed by oxidation and condensation.

Purpose

1. Veterinary coccidiostatic agent. Sulfaquinoxaline has the strongest effect on Eimeria giantis, Brucella brucei, and Eimeria aeruginosa in chickens, but it is less effective against tender and poisonous Eimeria, and usually requires a higher concentration to be effective. Therefore, this product is usually used in combination with amprolium or antibacterial synergists to expand the anti-insect spectrum and enhance the anti-coccidial effect. 2.Broad-spectrum antibacterial agent for animals. Sulfaquinoline has the strongest effect on Eimeria giganteum, Eimeria brucelli and Eimeria aeruginosa in chickens, but is less effective against tender and poisonous Eimeria, and usually requires a higher concentration to be effective. Sulfaquinoline has a narrow anti-insecticide spectrum and high toxicity, so it should be used in combination with other anti-coccidial drugs (such as amprolium or antibacterial synergists).
