Reaction Conditions:
with aluminum (III) chloride at 40; under 15001.5 Torr; for 4 h;Temperature;
Steps:
1.2; 3.2 Example 1
Step 1: Add 240 g (2 mol) of mesitylene and 66.7 g (0.5 mol) of catalyst AlCl3 to the reaction flask.Raise the temperature to 30 ° C and pass CO2 to 2 Mpa to stir the reaction for 5 hours.After the reaction is completed, the reactant is slowly injected into 50 ml of distilled water.Filtration, layering of the filtrate,The organic layer is washed with water, dried, and the filtrate is subjected to normal pressure recovery of mesitylene.Re-distillation26.1% of 2,4,6-trimethylbenzoic acid,The yield was 95.2%.
