    With the way

    Widely used in chemical synthesis catalyst in organic drug synthesis, pesticides, dyes, food additives, such as synthesis of acylation, hydroformylation, etherification, esterification, etc.4 - dimethyl aminopyridine is widely used in chemical synthesis in recent years a new type of high efficient catalyst, dimethyl amine and its structure for electronic mother ring resonance (pyridine ring), can strongly activated nucleophilic ring of nitrogen atoms to replace, significantly high resistance, low reactivity of alcohol and amine acylation (phosphorus acylation, sulfonyl, carbonyl) reaction, the activity is about 104-6 times of pyridine.In organic synthesis, drug synthesis, pesticide, medicine, dyes, spices, acylation of polymer chemistry, analytical chemistry, alkylation, etherification, esterification and ester exchange, and other types of reactions have higher catalytic ability, to improve the yield is extremely obvious
