Matters related to the melting point range of cinnamic acid

Taste the properties of the substance, and the melting point is important. For cinnamic acid, the identification of its melting point range is related to the quality and cannot be ignored.

Where measuring the melting point range of cinnamic acid, it is necessary to prepare delicate equipment and follow strict methods. Take an appropriate amount of cinnamic acid first, place it in a clean container, carefully grind it to make it uniform in texture. Then measure it with a melting point meter, pay attention to the heating rate, and do not rush to prevent errors.

Look at the melting point range, if it is within a reasonable range, it proves that the quality of cinnamic acid is acceptable. If it deviates from the normal, high or low, it is necessary to investigate the cause in detail. Or the raw materials are impure and contain other impurities; or the preparation method is wrong, resulting in structural mutation.

All matters depend on the care of the operator. Only with prudence and meticulous research can we determine the true meaning of the melting point range of cinnamic acid and lay a solid foundation for subsequent use.
