The method of making cellulose acetate
The method of making cellulose acetate is very impressive. It is also based on cellulose at the beginning. Cellulose, which exists in the cell walls of many plants in nature, is tough and has characteristics.

To make cellulose acetate, first take an appropriate amount of cellulose and place it in a special vessel. Next, add an appropriate amount of acetic anhydride, which is the raw material of chemistry and is active. When the two meet, add an appropriate catalyst, such as sulfuric acid. The catalyst can promote the speed of the reaction, but it does not change itself.

When reacting, be careful to adjust the temperature and pressure. The appropriate temperature is related to the urgency of the reaction; the appropriate pressure is also related to the smooth and reverse of the process. If the temperature is high, the reaction will be fast, but if it is too high, there will be side effects; if the pressure is large, the molecule will be easy to combine, and if it is too large, it will also change. Therefore, when the reaction is in progress, those who take care of it must always check it, and the heat preservation and pressure will be moderate.

After the reaction is completed, the product contains many impurities. It is the art of separation and purification. Or by filtration to remove its insoluble matter; or by distillation to analyze its miscible quality. After these several processes, pure cellulose acetate can be obtained. It is white in quality, flexible in nature, and has a wide range of uses. It can also be used as an important material in the textile, plastics, and other industries.
