The physical properties of cinnamic acid are related to classical Chinese:

Cinnamic acid, with special characteristics. Its color or light color, the quality is often crystalline, and the shape is like fine grains gathered, crystal clear and regular. When it is touched, it feels slightly hard, and when viewed under light, there is a small light flicker.

Its melting degree, after measurement, can be found to reach a certain value. When heated, it gradually melts and turns into a liquid. When the state changes, the temperature is fixed. As for its boiling degree, it also has a certain standard. When heated to a considerable extent, it can be seen as boiling, air rising and liquid surging, which are all its physical characteristics. And its solubility in various solvents is different. In a certain type of solvent, it is soluble and miscible; in other types, it is insoluble and divided, which is all about the affinity of its molecules and solvents, subtle and legal.
