the preparation method is to put the prepared acetaldoxime aqueous solution into the chlorination kettle from the oxime kettle, start stirring, pass frozen brine into the jacket of the chlorination kettle and the inner tube at the same time to cool down, start to pass chlorine gas when the temperature of the acetaldoxime aqueous solution drops to -18 ~-15 ℃, the speed of passing chlorine gas is controlled by the rotameter, and the total amount. The chlorination reaction temperature is strictly controlled at -10 ~-8 ℃, the chlorine gas is passed, the temperature is kept warm and stirred for 10min, then the vacuum pump is started, and the metered soda ash is slowly added into the chlorination kettle to neutralize the hydrogen chloride generated simultaneously with α-chloroacetaldehyde oxime. Reaction equation: CH3CH = NOH Cl2 & rarr;CH3CCl = NOH HCl
