3-羟甲基苯甲酸 - Reference Information
| Application | 3-hydroxymethyl benzoic acid is an important organic chemical raw material, it is an important intermediate for the synthesis of herbicides and insect repellents. It is also a good contrast agent for color film, and can also be used for artificial synthetic fragrance. |
| uses | 3-hydroxymethyl benzoic acid has a wide range of uses, mainly used as organic reagents, pharmaceutical intermediates. |
| preparation | 0.1g of catalyst, 12.0g of initiator and 115g of acetic acid were sequentially added to the reaction flask, and the temperature in the oil bath was raised. C, stirring to make it uniform, adding 10.6g of M-xylene, Dropwise adding 17.0g of hydrogen peroxide (condensed water reflux), dropping, heat preservation reaction 1~5H. The reaction was quenched in an ice bath, extracted with dichloromethane (3x5ml), and the content of the components was detected by HPLC. The crude product was purified by multistage series distillation to obtain 10.8g of 3-hydroxymethylbenzoic acid, with a yield of 80% and a purity of 95%. |
