Yield:536-66-3 98%

Reaction Conditions:

with diethylene glycol dimethyl ether at 70; for 0.5 h;Sonication;

Steps:

15 Example 15: Preparation of 4-isopropylbenzoic acid:

In a 10 mL round bottom flask, 0.75 g of 4-isopropylbenzyl alcohol was added in sequence.2 g of diethylene glycol dimethyl ether, the resulting mixture was subjected to ultrasonic irradiation at 40 KHz/30 W/70 ° C for 30 minutes in an ultrasonic reaction apparatus. The diethylene glycol dimethyl ether was removed under reduced pressure and recrystallized to give 0.79 g of 4-isopropylbenzoic acid, yield 98%.
