On the Preparation of Cinnamic Acid
If you want to make Trans-cinnamic Acid, you need to understand the method and pay attention to the process in order to achieve a delicate environment.

The method of making is often based on chemical principles, based on various things, and perform reaction techniques. Choose the appropriate raw materials, according to their proportions, and carefully prepare them. Or take so-and-so, according to a specific number, fuse them, and put them in a vessel.

Then, control the reaction environment. The temperature is very important. If the temperature is not good, or the reaction is slow and difficult to form, or the product becomes miscellaneous, it should not be pure. Therefore, it is necessary to use the skill of the heat to stabilize the temperature, so that it should be at a suitable temperature. And the length of time cannot be ignored. If it lasts for a long time, it may be damaged, and if it is short, it should not be finished.

After the reaction is completed, a mixed product is obtained. To obtain pure cinnamic acid, it is necessary to separate and purify it. It can be filtered, distilled, crystallized, etc. Filter to remove its solid impurities, steam to separate its liquid and mix it, and combine it to polymerize its pure quality. In the meantime, observe the state of the product and examine the signs of its change, so as to achieve pure cinnamic acid.

The preparation of cinnamic acid is not achieved overnight, and it is necessary to be careful, abide by the procedures, and gain insight into the changes in order to achieve its work and obtain high-quality cinnamic acid for various purposes.
