Abstract
Organic synthesis raw materials valeric acid synthesis method, comprises the following steps: 3 mol methyl propyl ketone, 4-6 mol tributyl citrate solution were added to the reaction vessel, controlled the stirring speed at 190-220 rpm, the solution temperature was reduced to 6-9°C for 60-80 min, and then the solution temperature was raised to 10-15 °C, added 3-4 mol chromium acetate by 3-6 times, interval for 30-40 min each time, continued to react for 2-3 h, and then standing for 60-80 min, added 300 ml potassium nitrate solution, standing for solution layer, the water layerextracted with 4-heptanone solution by 3-5 times, extracted with 3-methy1-2- pentanone solution by 4-6 times, combined with the oil layer and extraction, recrystallized in the isobutyl butyrate solution, dehydrated with dehydration, got the finished valeric acid.
