YieldReaction ConditionsOperation in experiment
99.5% 1) Under argon protection,Methyl p-methylcinnamate,Mix the auxiliary with 1,2-dichloroethane,Control the reaction temperature to 120 C,Pressure to 5 atmospheres,After stirring for 1.5 hours,Maintain reaction conditions,A mixed aqueous solution of tetrabutylammonium bromide and glacial acetic acid was added dropwise to control the dropwise addition time to 2 h, and after the completion of the dropwise addition, the temperature was controlled to 150 C.The pressure is up to 8 atmospheres and the reaction ends at 5h.The molar ratio of methyl methyl cinnamate, tetrabutylammonium bromide and glacial acetic acid is 1:0.82:1.6; the concentration of tetrabutylammonium bromide in the mixed aqueous solution is 20% by mass; The ratio of ester to 1,2-dichloroethane was 1 g: 5.2 mL.The auxiliary material is prepared by grinding diatomaceous earth to 250 mesh, adding to a mixture of potassium bromate aqueous solution and toluene, heating to reflux and separating water, removing water, evaporating the remaining toluene, and uniformly grinding the obtained solid. Obtained at 260 C for 2.5 h; the mass ratio of diatomaceous earth to potassium bromate aqueous solution is 1:3.2; the volume ratio of potassium bromate aqueous solution to toluene is 1:4.5; the concentration of potassium bromate aqueous solution is 18% by mass; p-methylcinnamic acid The molar ratio of the methyl ester to the potassium bromate in the auxiliary is 1: (0.25 to 0.28).2) After cooling the system, pour into 3 volumes of water, add dichlorohexane to extract, and the ratio of methyl methyl cinnamate to dichloromethane is 1g: 4.5mL; after extraction, layering, organic layer After washing with water and drying over anhydrous sodium sulfate, the solvent was concentrated by evaporation on a rotary evaporator to give the product. The molar yield was 99.5% and the GC purity was 99.3%.
