Its preparation method is: adding catechol, 25% sodium hydroxide solution, chloroethane and solvent into autoclave, and then heating to 90 ℃ and then keep 5h, and then have de-solvent, filtering to get the product: 1,2-Diethoxybenzene (2050-46-6).Etherification agent can also be replaced with Dimethyl sulfate , O-p-toluenesulfonate ester , Ethyl iodide , Ethyl bromide and so on, but using of chloroethane as etherification agent, it is better fpr raw materials readily available, inexpensive, low cost, high yield characteristics.
