The method of brominating trans-cinnamic acid
This is about brominating trans-cinnamic acid. In a clean vessel, put an appropriate amount of trans-cinnamic acid, and slowly inject an appropriate amount of bromine solution. The liquid is clear and lively.

At that time, the room was quiet, and only the sound of liquid droplets touching each other was heard. The two met for the first time, and they became slightly turbulent, and then the reaction gradually intensified. The structure of trans-cinnamic acid changes when it encounters bromine. At the double bond, bromine atoms are quietly embedded, like exquisite craftsmen carving beautiful jade.

During the reaction, heat may escape, so the temperature must be well controlled, so that the temperature is not too high and the product will change. Coat it with a condenser to prevent it from evaporating.

When the reaction slows down, the color of the solution also changes, from the initial color to a new state. Then, by applying separation techniques, through filtration, washing, drying and other methods, the product can be obtained. The product is in the state of crystalline, with a warm luster. This is the result of brominated trans-cinnamic acid. The whole process, see the effort in detail, and each step is interconnected to get a good product.
