Abstract
PURPOSE: To prepare the titled compound useful as a polymerization catalyst, in high quality and yield, by reacting 2,2'-hydrazo-bis(4-methoxy-2,4-dimethylvalero- nitrile) with a halogen at a specific low temperature, and separating the objective compound at a specific temperature.
CONSTITUTION: 2,2'-Hydrazo-bis(4-methoxy-2,4-dimethylvaleronitrile) of formulaI is made to react with the halogen of formula X2 (e.g. Cl, Br, etc.) at -60W -11°C, and the crystals precipitated from the reaction liquid are separated at ≤-20°C to obtain the objective compound of formula II. The reaction is carried out in a solvent such as methanol, isopropanol, etc., and the amount of the halogen is equivalent or somewhat excess to the compound of formulaI. The reaction system is cooled by circulating a cooling medium such as an aqueous solution of calcium chloride cooled with e.g. a two-stage compression refrigerator. The objective compound having light color and low irritant smell can be obtained by this reaction process.
