2-aminoniacin is an important intermediate of medicine and pesticide. It is traditionally obtained by activating pyridine ring from 3-cyanopyridine or 3-amidopyridine, and then hydroxylation in 2-position chloride of pyridine ring. Due to the complex synthesis route and low yield, the cost of 2-aminonicotinic acid is very high. At present, the price of 2-aminonicotinic acid remains high, which increases the cost burden for the promotion and use of its downstream products.

Brief Introduction

3,3-dimethylacrylic acid is widely used in medicine, pesticide, perfume and surfactant. Perfume is used in washing and chemical products, which can remove dandruff and relieve itching, and is non-toxic and non irritating. As an intermediate of pesticide and medicine, it plays an important role in drug synthesis and pesticide synthesis. For example, it is used as raw material for synthesizing pyrethroids by Martel method, and the raw material of pyrethroids is used to synthesize excellent insecticides with high efficiency, low toxicity and no resistance
