Abstract
Organic intermediates dimethylacetic acid synthesis method, comprises the following steps: 2 mol 3-bromo-isopentene and 4-6 mol glycerol triacetate were added to the reaction vessel, controlled the stirring speed at 130-170 rpm for 30-50 mm, reduced the solution temperature to 7-10°C, then add 3-5 mol vanadium dioxide, reacted for 60-80 min, and then added 1500 ml potassium bromide solution by 3-5 times, interval for 20-30 min each time, reduced the temperature to 3-5°C, after addition, standing for 2-4h, washed with sodium sulfate solution in 3-5 times, extracted with 3-methoxy propionitrile solution by 4-6 times, extracted with o-dibromobenzene solution by 5-8 times, recrystallized in o-chloroaniline solution, dehydrated with the dehydrating agent, got the finished dimethylacetic acid crystals.
