Triacetin（TR-01-F0101）

Triacetin (TR - 01 - F0101) has a wide range of main uses. In the field of medicine, it is often used as a medicinal excipient. Because of its good solubility and stability, it can help the drug components to disperse evenly, increasing the stability and bioavailability of the drug. For example, in some oral preparations, it can be used as a solvent to make insoluble drugs more easily absorbed by the human body; in local external preparations, it can help active ingredients penetrate the skin and improve the efficacy. In the food industry, Triacetin also has important functions. It can be used as a food additive, such as as a plasticizer and a stabilizer. In chewing gum and other foods, it can increase its flexibility and chewability, and improve the taste; in oily foods, it can prevent oil oxidation and rancidity, prolong the shelf life of food, and maintain food flavor and quality. Furthermore, in the field of cosmetics, Triacetin can be used as a moisturizer and solvent. It can form a moisturizing film on the surface of the skin, lock in water and moisturize, and make the skin hydrated; when used as a solvent, it can dissolve a variety of cosmetic ingredients, helping to prepare uniform and stable products, such as lotions, creams, etc. In addition, in the plastics industry, Triacetin can be used as a plasticizer to enhance the flexibility and plasticity of plastics, making plastic products easier to process, and can improve their physical properties and broaden the application range of plastic products. Overall, Triacetin has a wide range of uses and is valuable in a wide range of industries.

The physical properties of triacetin (TR - 01 - F0101) can be investigated. At room temperature, this substance is a colorless and transparent oily liquid, which is clear. Its taste is slightly fragrant, pleasant to smell, not pungent. As for its density, it is about 1.155 - 1.163g/cm ³, which is slightly heavier than water. When it is poured into the water, it can be seen that it slowly sinks to the bottom of the water, and the two are distinct. Its melting point is -78 ° C, which is very cold. At this temperature, it condenses into a solid state. If it is placed at room temperature, it immediately turns into a flowing liquid. The boiling point is 258-259 ° C, and high temperature is required to make it boil and vaporize. The solubility of triacetin is also specific. It can be miscible with many organic solvents such as alcohols, ethers, and chloroform. When mixed, it is indistinguishable from each other and fuses into one. However, in water, it is only slightly soluble, a small amount can still be dispersed, and a large amount can be stratified. In addition, the refractive index of triacetin is about 1.4301. When light passes through, it is refracted according to this rate, presenting a unique optical phenomenon. Its viscosity is also moderate, and when it flows, it does not stagnate and does not slow, showing specific fluid properties. These physical properties are of great significance in various fields such as chemical engineering and medicine, and are relevant to their effectiveness and scope of application.

Triacetin (TR - 01 - F0101) is also an organic compound. When storing and transporting, many matters must be paid attention to. First words storage. This substance should be placed in a cool and well ventilated place. The indoor temperature should be controlled within a certain range, not too high, to prevent its properties from changing. It is also necessary to keep dry and avoid humid places. Due to moisture or chemical reactions caused by it, its quality will be damaged. And it should be stored separately from oxidizing agents, acids, etc., which are in contact with them and are prone to violent reactions and endanger safety. Where it is stored, clear warning signs should be set up so that everyone is aware of its characteristics and potential dangers. As for transportation. Transportation vehicles must be equipped with good ventilation equipment to disperse harmful gases that may be generated. When loading, it should be handled lightly and unloaded lightly. Do not operate brutally to avoid damage to the packaging and leakage of triacetin. During transportation, the bumps and vibrations of the vehicle should be avoided too violently to prevent damage to the packaging. Escort personnel must be familiar with its nature and emergency treatment methods, and pay attention to the condition of the goods at any time during the journey. In case of emergencies such as leakage, they should be dealt with immediately according to the established emergency plan to evacuate the surrounding people and prevent the expansion of the accident. Packaging materials also need to be strong and durable, able to withstand certain external forces, to ensure the safety of the whole transportation process.

Triacetin (TR - 01 - F0101) is the English nickname for glycerol triacetate. Its preparation process has been around for a long time, and it has been honed over time, and it has become more and more refined. Preparation of Triacetin, the first choice of raw materials. Commonly used, glycerol and acetic acid are also. These two are easy to obtain and of good quality, and are the cornerstone of synthesis. When reacting, sulfuric acid is often used as a catalyst, because of its high catalytic activity, which can promote the reaction to go fast. Dip glycerol and acetic acid into the reactor in an appropriate ratio, add an appropriate amount of sulfuric acid, and then heat up to a suitable temperature, generally about 110-130 ° C. At this temperature, the esterification reaction occurs between the two. This process requires careful temperature control to prevent overheating from causing side reactions. During the reaction, constant stirring is required to make the reactants fully mixed to facilitate uniform reaction. When the reaction comes to an end, the acid value of the reaction system drops to a certain extent, which can be regarded as the reaction is basically completed. However, at this time, the product still contains impurities and needs to be purified. Neutralize with sodium carbonate solution to remove sulfuric acid, then wash with water to remove excess salts. Then, by distillation, pure Triacetin is obtained. During distillation, the temperature is controlled near the boiling point of Triacetin, so that the product is steamed out, thereby separating it from the high boiling point impurities. Through this process, high-purity Triacetin can be obtained, which can meet the needs of all parties and play its unique role in many fields such as medicine, food, and chemical industry.

Triacetin (TR - 01 - F0101) has many Quality Standards, which you will describe in detail today. First, the appearance needs to be clear and transparent, without visible impurities. Second, the content determination is quite critical. The content of triacetin should reach a specific standard. Third, acidity cannot be ignored. It needs to be maintained within a reasonable range. Too high or too low acidity may affect its performance and application. Fourth, the moisture content also has strict requirements. A small amount of moisture may affect its stability and related properties, so it needs to be precisely controlled, just like controlling the heat, it cannot be exceeded or inferior. Fifth, density is also one of the important indicators. Only by meeting the established density range can we ensure the stability of its physical properties, just like the size of the object needs to be in accordance with the rules to be stable. Sixth, the refractive index is also considered in the Quality Standard. The specific refractive index reflects the characteristics of its internal structure and composition, just like a person's fingerprint, which is its unique logo. All these Quality Standards are to ensure the high quality of triacetin, so that it can be applied to various application scenarios and play its due effectiveness.
