In terms of chemical activity, triacetin contains ester groups and has the typical chemical properties of esters. It can undergo hydrolysis reaction catalyzed by acids or bases. Hydrolyzed under acidic conditions, acetic acid and glycerol are slowly formed; in alkaline environments, the hydrolysis rate is significantly accelerated, and this saponification reaction can be used to prepare acetate and glycerol. At the same time, due to the presence of ester groups, triacetin can participate in reactions such as alcoholysis and aminolysis, and can be substituted with alcohols and amines to form new esters or amides. This property provides many possible paths for organic synthesis.

In addition, triacetin also has characteristics of solubility. It can be miscible with most organic solvents, such as ethanol, ether, acetone, etc., but slightly soluble in water. This difference in solubility makes it play an important role in the separation, purification and formulation design of different solvent systems. Because it can dissolve with a variety of organic solvents, it can be used as a solvent or plasticizer in coatings, inks, plastics and other industries to enhance the flexibility and processability of materials.

What is the production process of Triacetin (TR - 01 - F02)?

Triacetin (TR - 01 - F02) is an important product in the chemical industry. Its preparation process is quite complicated and delicate.

At the beginning, suitable raw materials need to be prepared. Glycerin and acetic acid are the main ones, both of which must be selected to ensure purity and no impurities. For glycerin, take the first-class product, the texture is pure, and impurities are rare; acetic acid also requires high purity and high quality.

The obtained raw materials are entered into the reaction process. In a special reactor, glycerin and acetic acid are injected in an appropriate ratio. The proportion is crucial, which is related to the purity and yield of the product. Generally speaking, according to precise stoichiometry, careful preparation. < Br >
Then, add an appropriate amount of catalyst. This catalyst can speed the reaction process and make the reaction efficient and smooth. Commonly used, there are strong acid catalysts such as sulfuric acid, which have strong activity and can greatly promote the esterification reaction of glycerol and acetic acid.

When reacting, temperature control and pressure control are also key. The temperature must be maintained within a specific range, usually at a moderate high temperature, but not too high, so as not to cause side reactions to breed. The pressure also needs to be stable in a suitable range to ensure the stability of the reaction environment.

After the reaction is completed, the product is mixed with unreacted raw materials, catalysts and by-products. Then proceed to the separation and purification sequence. First, the volatile ones are separated by distillation according to the boiling point of each component. Then extraction, crystallization and other techniques are used to further remove impurities and improve the purity of Triacetin. After these many processes, high-quality Triacetin products are obtained. The whole process is interconnected, and each step needs to be carefully controlled to obtain high-quality Triacetin.

What is the price range of Triacetin (TR - 01 - F02) in the market?

In today's world, the price of tri-vinegar (TR-01 - F02) sold in the market is uncertain, and it often changes for many reasons. There are probably three reasons for this. First, the output of the place of origin is different. If the place of origin is vast, the product is abundant, the production capacity is sufficient, and the market is full, the price may be leveled. On the contrary, if the place of origin is narrow, the output is meager, and the supply is in short supply, the price must be raised. Second, there is a difference between high and low quality. Those with excellent quality have been meticulously crafted, and there are few impurities. They have a wide range of benefits, and the price should be expensive. Those with poor quality contain more impurities, and the effect is slightly inferior, and the price will also drop. Three changes in market supply and demand. If there are many buyers in the market and the demand is strong, the price will rise even if there is no big difference in production and supply. On the contrary, if there is little demand, the price of triacetin may drop in order to promote sales.

Looking at the past market conditions, the price of triacetin often hovers between thousands and more than 10,000 yuan per ton. When the market conditions are stable, the price may be between 5,000 and 6,000 yuan per ton. However, in times of market fluctuations, scarcity of raw materials, or sudden increase in demand, the price may jump to 10,000 yuan per ton, or even higher. As for the current exact price, it is difficult to hide it. It is necessary to visit the chemical market in real time, consult merchants, or observe industry information to obtain the exact number.

Triacetin (TR - 01 - F02) Quality Standards

Triacetin (TR - 01 - F02) is an important organic compound and is related to many Quality Standards. Its appearance standard, when it is a colorless, transparent, oily liquid with a pleasant smell, if there are impurities or abnormal color, it will affect its quality and application. The

content standard is quite critical, usually needs to reach a high purity, such as 99% or more. Insufficient content will cause it to perform poorly in various reactions or product applications. The

acid value standard cannot be ignored, and should be maintained at a very low level, generally not exceeding 0.2 mgKOH/g. Excessive acid value indicates that the product contains too much free acid, which will corrode the equipment and affect the stability and reaction process of the product.

The moisture standard is also strict, and the moisture content often needs to be controlled below 0.1%. Too much moisture can interfere with the reaction, or cause the product to hydrolyze and damage the quality.

The chromaticity standard is measured by APHA value and should generally be less than 20. High chromaticity indicates that the product contains color impurities, which affect the appearance, and may suggest that the product is contaminated or the production process is defective.

The relative density standard also stipulates that at a specific temperature, such as 20 ° C, the relative density should be between 1.155 and 1.163. Deviation from this range may mean that the product ingredients are not pure. The

refractive index standard is also the basis for quality judgment. At a specific temperature, such as 20 ° C, the refractive index should be between 1.429 and 1.431, indicating abnormal refractive index or reflecting product purity and composition problems.
