| titleOfInvention | A kind of new technique for synthesizing of tetrazoleacetic acid |
| abstract | The invention discloses a kind of new technique for synthesizing of tetrazoleacetic acid, N- formylglycine is prepared by formic acid and glycine heating reflux reaction first, then 5- oxazolidone is prepared using acetic anhydride as dehydrating agent, finally, tetrazoleacetic acid is prepared under the catalytic action of zinc bromide in itself and sodium azide.The involved reaction of new technique for synthesizing of the invention carries out in water phase, largely using and waste for organic solvent is avoided, cost, and the generation without " three wastes " can be effectively reduced, meet the requirement of greenization production, and synthetic method of the present invention is simple, easy control of reaction conditions, aftertreatment technology is easy, with very strong operability and repeatability, and product purity is higher, can be effectively reduced cost, be convenient for industrialized production. |
