"On the Source of Triacetin"

Triacetin comes from a wide range of sources. First, it is derived from natural oils and fats. Oils and fats are common in animals and plants. After hydrolysis, fatty acids and glycerol can be obtained. And glycerol and acetic acid are esterified to produce triacetin. In this process, the conditions for oil hydrolysis are quite critical, and factors such as temperature and catalyst affect the rate and degree of hydrolysis. And when esterification reaction, it is also necessary to precisely control the reaction conditions, such as the proportion of reactants, reaction temperature and time, to obtain high-quality triacetin.

Second, chemical synthesis is also one of the sources of triacetin. Using acetic anhydride and glycerol as raw materials, under the action of appropriate catalysts, the two occur acylation reaction, and triacetin can be prepared. The method of chemical synthesis can precisely adjust the quality and output of the product according to demand. However, it requires quite high requirements for the purity of raw materials, reaction equipment and operation technology, and a little carelessness will affect the quality of the product.

Triacetin is a source of natural extraction and chemical synthesis. Triacetin from natural sources may have natural characteristics; the method of chemical synthesis can achieve large-scale production and meet diverse needs. It is of great significance to explore better sources for the application and development of triacetin.
