Product Description

Production method

The preparation method comprises the following steps of: adding anhydrous acetonitrile, methanol and solvent carbon tetrachloride into a reaction kettle, cooling to -10 DEG C, adding metered dried HCl gas into the reaction kettle, gradually warming to 0 ~ 5 ℃, stirring was continued at this temperature for 12h to obtain a crude imino ether hydrochloride reaction mixture, the reaction solution was neutralized with 28% sodium methoxide in methanol to pH = 6.5, additional pre-cooled methanol was added Alcoholysis, the temperature is controlled at 5 ℃, and then heated to 35 ~ 40 ℃, stirring was continued for 10h, then cooled to 0 ~ 5 ℃, ammonium chloride was removed by suction filtration, the filtrate was neutralized with 28% sodium methoxide in methanol to adjust the pH = 8, and then filtered, and then distilled to remove the solvent carbon tetrachloride, and then collected 107 ~ 110 ° C fraction of trimethyl orthoacetate, the yield of up to 90%.
