On the study of the melting point range of cinnamic acid
The nature of the material is often distinguished from the various ends, and the melting point is one of them. Cinnamic acid is often studied, and its melting point range is related to its purity and impurities, physicochemical properties, so there are many people who study it.

If you want to know the melting point range of cinnamic acid, you should first know the method of measuring it. In the past, many sages used the method of hot bathing, putting cinnamic acid in a glass tube, accompanied by a thermometer, gradually heating up and observing its change. The urgency of heat is related to the accuracy of observation. Urgent is the uneven temperature, and the cinnamic acid has not been heated all over, and the measured number is wrong; slow is time-consuming, but the true number can be obtained.

Looking at the records of various experiments, the melting point range of cinnamic acid is often different. The reason for this is that there are two ends to the source. First, the quality of cinnamic acid. If the system is impure, the melting point will change between the impurities. For impurities, either reduce the melting or expand the range. If it contains fusible impurities, the melting time will be advanced; if the impurities are difficult to melt, the melting time will be delayed and the range will be widened. Second, the equipment and method of measurement. Whether the thermometer is accurate or not depends on the reading; the heat transfer of the hot bath agent, water and oil are different; the rate of heating, the speed is different, and the melting point range is different.

In the past, some researchers used precise tools and rigorous methods to measure the melting point range of cinnamic acid. First purify the quality, remove the chores, and then slowly raise the temperature with an oil bath, which must be carefully observed at every degree. The obtained number is narrower and more accurate than that of the regular testers. It can be seen that in order to obtain an accurate melting point range of cinnamic acid, both purity and good law are indispensable.

Today's researchers should follow the method of wisdom, make good use of new tools, and study their methods to make the measurement of the melting point range of cinnamic acid more accurate. This is of great benefit to the chemical and pharmaceutical industries. Chemists can make pure products with this; medical people can determine the quality according to this. Therefore, the study of the melting point range of cinnamic acid is not only the nature of knowing one thing, but also the progress of all karma.
