| titleOfInvention | Method for continuously producing pyridine boric acid |
| abstract | The invention provides a method for continuously producing pyridine boric acid, which comprises the following steps: reacting the first reaction raw material and the second reaction raw material in the microchannel reactor to generate a first reaction product; reacting the first reaction product with hydrochloric acid in a microchannel reactor to obtain a crude reaction solution; post-treating the obtained crude reaction liquid to obtain the pyridine boric acid product; the first reaction raw material is organic solution of alkyl lithium or phenyl lithium; the second reaction raw material is a mixture consisting of 2-nitrile-5-bromopyridine, alkyl borate and an organic solvent. The method of the invention utilizes the characteristic that the microchannel reactor has strong mass transfer and heat transfer effects to promote the first reaction raw material, the second reaction raw material and the hydrochloric acid to be fully mixed in a very small structural size and take away a large amount of heat released by the reaction in time, so that the reaction time is shortened by more than 20 times, and the method has remarkable effects of reducing energy consumption and improving productivity and has great social value. |
