| titleOfInvention | Synthesis process of ethyl maltol |
| abstract | The invention belongs to the technical field of maltol, and particularly relates to a synthesis process of ethyl maltol. The process comprises mixing nano TiO 2 Loading carbon nano tube on stainless steel wire mesh filler of an ultrasonic rotating packed bed, adding acetonitrile solution into the rotating packed bed, starting an ultrasonic generator, controlling the temperature in the packed bed to be 30-70 ℃, respectively introducing alpha-furylalcohol and 10-30% hydrogen peroxide from two liquid inlets of the ultrasonic rotating packed bed, simultaneously controlling the rotating speed of the ultrasonic rotating packed bed to be 400-fold-over-1000 r/min, and reacting for 1-3H to generate 6-hydroxy-2-ethyl-2H-pyrone- [3]]The intermediate product is mixed with solution, and then acetalization, oxidation and hydrolysis are carried out to prepare the ethyl maltol. The method has the advantages of environment-friendly process, easy process control, high catalytic efficiency, less reaction time consumption and high yield of intermediate products up to 93 percent. |
