| titleOfInvention | Catalytic oxidation method for 1,2-propanediol |
| abstract | The invention relates to a method of preparing lactic acid, and particularly relates to a method of preparing lactic acid by catalyzing oxidation of 1,2-propanediol by adopting nanometer Au-Pd double metals supported by nanometer magnesium hydroxide as a catalyst. The method includes: adding the 1,2-propanediol, sodium hydroxide, water and the catalyst into a high-pressure reactor in order to form a mixed solution, feeding oxygen, adjusting the pressure of the oxygen to be 0.3-1.5 MPa, starting a stirring device, stirring, raising the reaction temperature to 20-80 DEG C, reacting for 20-50 min, acidizing a reaction product after the reaction is finished to obtain the lactic acid, analyzing by utilization of high performance liquid chromatography and calculating the result. The catalyst is free of activation processing and small in using amount, achieves a high conversion rate of the 1,2-propanediol and high lactic acid selectivity in a short reaction time, and has good catalytic stability. |
