| Use | 4-ethylbenzoic acid is an intermediate of the insecticide fenozide, methoxyfenozide. chemical intermediates. used as liquid crystal raw materials and intermediates, can also be used for carbon nanotube material initiator, can also be used for the production of pesticides. used as liquid crystal raw materials and intermediates, also used in the production of pesticides |
| production method | the preparation method is to add ethylbenzene and trichloroacetaldehyde in the reactor, and add anhydrous aluminum trichloride in batches at 0 ℃, after addition, stir the reaction at -10~0 ℃ for 2H, then add dilute hydrochloric acid to the mixture to decompose the remaining aluminum trichloride, then wash with NaHCO3 and water, and recover ethylbenzene by distillation of organic layer, the mixture was distilled to obtain p-Ethylbenzene -2,2, 2-trichloroethanol, and then the trichloroethanol was dissolved in methanol, and then NaOH solution was added to stir. In the mixture, 30% aqueous hydrogen peroxide was added dropwise, the mixture was stirred until the trichloroethanol disappeared and then acidified with HCl to give crystals, I .e., the product. |
