Method for preparing isothiocyanate from ethyl chloroformate

The invention relates to a method for preparing isothiocyanate from ethyl chloroformate. The method comprises the following steps: taking a compound as shown in specification as a starting material, reacting with carbon disulfide to prepare inner salt, and then reacting the inner salt with ethyl chloroformate in an organic solvent at the temperature of 0-40 DEG C to prepare thio-mixed anhydride, wherein in the compound as shown in specification, n is 1, 2, 3, 4 or 5; and adding the mixed anhydride in an inorganic aqueous alkali, and hydrolyzing at the temperature of minus 5-30 DEG C to preparethe corresponding isothiocyanate. According to the preparation method, the mixed anhydride is synthesized at first, and then is hydrolyzed with inorganic alkali, application of organic alkali is avoided effectively, side reaction of the isothiocyanate and alcohol is relieved, and the reaction yield of the isothiocyanate and the purity of the product are improved.
