Application:It is widely used as a catalyst for chemical synthesis, acylation, carbonylation, etherification and esterification in the synthesis of organic drugs, pesticides, dyes, food additives, etc. 4-Dimethylaminopyridine is a new type of high-efficiency catalyst widely used in chemical synthesis in recent years. The resonance of the electron-donating dimethylamino group with the parent ring (pyridine ring) in its structure can strongly activate the nitrogen atom on the ring for nucleophilic substitution.Remarkably catalyze the acylation (phosphorylation, sulfonylation, and carbonylation) of alcohols and amines with high steric hindrance and low reactivity and its activity is about 104-6 times that of pyridine. It has high catalysis in various types of reactions such as organic synthesis, drug synthesis, pesticides, medicine, dyes, perfumes, polymer chemistry, analytical chemistry, such as acylation, alkylation, etherification, esterification and transesterification. Ability to improve the yield is extremely obvious.
