| titleOfInvention | A kind of synthetic method of 4- pyridinemethanol |
| abstract | The present invention relates to organic chemistry filed, specifically a kind of synthetic method of 4- pyridinemethanol includes the following steps；Using 4- picoline as raw material, in acid condition, 4- pyridine nitric oxide is obtained by oxidation reaction；The 4- pyridine nitric oxide resets synthesis of acetic acid -4- picolyl by the way that aceticanhydride is acylated；Acetic acid -4- the picolyl hydrolyzes to obtain 4- pyridinemethanol.A kind of synthetic method of 4- pyridinemethanol of the invention reduces cost while having the advantages that 1, can obtain preferable hydrolysis rate using the potassium hydroxide solution of mass percent 20%；2, using hydrogen peroxide as oxidant, oxidizing condition is mild, at low cost, fully reacting；3, total recovery of the present invention is high, and production cost is low, is easy to industrial scale production. |
