81517-60-4 - Preparation

Reaction of 1-vinylimidazole with bromoethane in a molar ratio of 1:1.2. A certain amount of 1-vinylimidazole is placed in a three-mouth flask, bromoethane is placed in a constant pressure funnel, and the funnel is connected with the flask, and the dripping speed of the constant pressure funnel is adjusted to 1 drop/3s, so that bromoethane is dripped into the three-mouth flask to react with 1-vinylimidazole. The reaction is an obvious exothermic reaction. As the reaction progresses, it can be observed that the liquid of the system gradually becomes viscous. After dropping bromoethane, react for a period of time to completely react 1-vinylimidazole, and then let it stand at room temperature to completely crystallize the reaction product to obtain white crystals.
