Msds 2 bromobutane
The method of making 2-bromobutane
If you want to make 2-bromobutane, you need to use a suitable method. First take n-butanol and place it in a clean container. With hydrobromic acid, mix the two, and the ratio must be appropriate. The combination of the two phases, like the intersection of yin and yang, is the starting point of the reaction.
In order to promote its reaction, it often needs to be heated. To slow down the fire, the temperature in the container gradually rises. At this time, the interaction between molecules is very active. The bromine atom of hydrobromic acid gradually combines with the carbon connected by the hydroxyl group in the n-butanol, and the hydroxyl group leaves in the state of water, thus forming 2-bromobutane.
However, in the reaction, impurities are easy to form. Or there is a genus of butene, because the reaction conditions are slightly poor. Therefore, after the reaction is completed, the impurity should be removed by refining method. You can first use the technique of liquid separation to separate the oil layer from the water layer. 2-bromobutane has a high density and is more settled. Later, by distillation, take the appropriate fraction to obtain pure 2-bromobutane.
This method of preparing 2-bromobutane, although the steps are slightly complicated, but it will be successful with care.
