The method of making 1-bromo-2-chloroethane
To make 1-bromo-2-chloroethane, you need to use a suitable method. Prepare the required materials first, such as ethylene, hydrogen bromide, chlorine, etc., all are pure products, do not contain impurities, so as not to miss this reaction.
In a clean and dry reactor, pass an appropriate amount of ethylene gas. Control the temperature of the reactor to a suitable degree, generally about [X] ° C. Slowly introduce hydrogen bromide gas, and observe it closely so that the two are fully combined. The reaction between ethylene and hydrogen bromide can be obtained according to its chemical properties.
After this step is completed, the obtained bromoethane is transferred to another reactor. The temperature is re-adjusted to [Y] ° C, and chlorine gas is introduced. Chlorine and bromoethane should be carefully controlled in time, so that it mainly produces 1-bromo-2-chloroethane.
After the reaction is completed, the product is purified by distillation. According to the boiling point of 1-bromo-2-chloroethane and the difference with other substances, fractionate to obtain pure 1-bromo-2-chloroethane.
The whole process requires strict compliance with operating regulations and heavy safety protection. The materials used are dangerous, such as ethylene flammable, hydrogen bromide, chlorine gas toxic and corrosive. The operating room must be well ventilated and equipped with protective equipment to prevent accidents. In this way, pure 1-bromo-2-chloroethane can be obtained.
