摘要

在40 ~ 150℃、0.5 ~ 3.0 MPa氧压条件下，以氧为氧化剂的乙醇溶液中，在T(o-Cl)PPMn的催化下，3-吡啶高效氧化制烟酸。考察了温度、氧压、反应时间、3-吡啶浓度、氢氧化钠浓度、T(o-Cl)PPMn催化剂浓度等因素对烟酸合成的影响。结果表明，T(o-Cl)PPMn在3-吡啶氧化制烟酸过程中表现出优异的催化活性，烟酸的产率随反应温度、氧压、T(o-Cl)PPMn浓度等因素变化较大。

Preparation of Nicotinic Acid from Oxidation of 3-Picoline with Oxygen Under Catalysis of T(o-Cl)PPMn

The oxidation of 3-picoline to nicotinic acid took place efficiently in an ethanol solution with O₂ as the oxidant under the catalysis of T(o-Cl)PPMn at 40—150 °C and 0.5—3.0 MPa oxygen pressure. The influences of temperature, oxygen pressure, reaction time, concentration of 3-picoline, concentration of sodium hydroxide, and concentration of T(o-Cl)PPMn catalyst, etc. on the production of nicotinic acid were investigated. The results show that T(o-Cl)PPMn presented excellent catalytic activity in the oxidation of 3-picoline to nicotinic acid and the yield of nicotinic acid varied greatly with the reaction temperature, oxygen pressure, T(o-Cl)PPMn concentration, etc.
