2,4-Dimethylphenylacetic acid - Reference Information
| the application of | (2, 4-benzenedimethyl) acetic acid as a phenylacetic acid derivative has received more and more attention from pharmaceutical and chemical researchers. |
| preparation | a 500 mL Four-necked flask was charged with 75 g of water, 118 g of concentrated sulfuric acid, slowly Dropwise add 150 g of 2, 4-dimethylphenylacetonitrile under reflux, incubate for 1 hour, distill off about 30 g of water, and then react at 130~140 ℃ for 3 hours, after the reaction is finished, the acid water is discharged by sedimentation at 100~110 ℃ for 15 min. After additional g of water is added, the low boiling matters are removed by heating and stripping, and about 50 g of water is distilled off, then cooled, crystallized and suction filtered, the resulting wet acid was dried by vacuum dehydration at 100 °c to give the finished (2, 4-benzenedimethyl) acetic acid. |
