| Use | O-diethoxybenzene is an intermediate of the fungicide Epsilon. It is used as raw material of medicine and pesticide intermediate, and it is also the intermediate of fungicide, |
| production method | the preparation method is to add catechol, 25% sodium hydroxide solution, ethyl chloride and solvent into the autoclave, heating to 90 deg C after the heat preservation reaction 5h, and then desolvation, filtering that O-diethoxybenzene, drying can be yellowish solid, that is, the product. The etherifying agent may also be dimethyl sulfate, ethyl O-toluenesulfonate, ethyl iodide, ethyl bromide and the like, but the use of ethyl chloride as the etherifying agent has the characteristics of easy availability of raw materials, low price, low cost, high yield and the like. |
