    Frequently Asked Questions

    As a leading Diacetin supplier, we deliver high-quality products across diverse grades to meet evolving needs, empowering global customers with safe, efficient, and compliant chemical solutions.

    What are the main uses of Diacetin?
    Diacetin is widely used in many fields, mainly as a plasticizer, solvent and additive: in the tobacco industry, it is used for plasticizing cigarette filters to improve flexibility and adsorption; in the food field, it is used as an additive as a flavor fixative, solvent and plasticizer; in the daily chemical industry, it is used in cosmetics and other products as a solvent and moisturizer; in the pharmaceutical field, it can act as a drug carrier and solvent; in addition, it can also play a solvent role in industrial scenarios such as coatings and inks.
    What are the physical properties of Diacetin?
    The physical properties of Diacetin are as follows: it is a colorless, transparent, and aromatic oily liquid at room temperature. It is miscible with organic solvents such as ethanol, ether, and chloroform. It is soluble in water but the solubility is limited. The melting point is about -30°C, the boiling point is around 258°C (under normal pressure), the relative density (25°C) is about 1.155-1.165, the refractive index (n20/D) is about 1.430-1.435, the viscosity is moderate, it is not volatile, it is hygroscopic, the chemical properties are relatively stable at room temperature, it is not easy to burn but it is a flammable liquid.
    Is Diacetin chemically stable?
    The name of diacetin is glyceryl diacetate. Its chemical properties are determined. This is because of its molecular properties. The glycerol part of the acetate group in the molecule is determined by the phase of the ester, and the transformation of the ester is qualitative. In the normal environment, diacetin is liquid and has a certain viscosity. It is often transformed into a normal environment, indicating the inertness of the phase. For example, in the environment of dilute acid and dilute environment, short-term production is difficult to produce. However, if it is placed in the environment of acid, water and added water, the ester can be hydrolyzed and cracked to form glycerol and acetic acid. And because of its certain properties, it has good solubility in solution. And in the normal existential environment, such as climate change and dryness, its chemical properties can be maintained over time, and there is little self-decomposition or reaction. Moreover, under the general chemical environment, the chemical properties are determined.
    What are the precautions for Diacetin in the production process?
    In the process of making diacetin, many matters need to be paid attention to. The first raw materials, glycerol and acetic acid, are selected as high quality. If there are many impurities, the product will be impure and the quality will be difficult. And the ratio of the two must be accurate, the ratio is inappropriate, the reaction is difficult to complete, and the yield will drop. The reaction conditions are also critical. The temperature needs to be controlled in an appropriate range. If it is too low, the reaction will be slow and take a long time. If it is too high, side reactions will occur and the product will be contaminated. The pressure cannot be ignored, and the appropriate pressure can promote the reaction to produce products. The choice and dosage of catalyst have a great impact on the reaction rate and yield. The one with good activity and high selectivity should be selected, and the dosage should be determined according The reaction equipment should be clean and suitable, with improper materials, or interact with the reactants and products, which will damage the quality of the products. Stirring should also be uniform, so that the materials are fully contacted and the reaction is uniform. The post-treatment process should not be underestimated. The method of product separation and purification should be appropriate, and the methods of distillation, extraction, crystallization, etc. should be selected according to the characteristics of the product and the nature of impurities. The operation process must be rigorous to prevent product loss or the introduction of new impurities. In addition, the safety of production should not be forgotten. The reactants and products may be corrosive and flammable. When operating, follow safety regulations, equip with protective equipment, and prepare emergency facilities to ensure stable production and personnel safety.
