Reaction: Firstly, the DL-panthenol lactone and amino propanol are mixed in a specific ratio and placed in a container. Through a series of chemical reactions, the desired product is obtained.
Freeze Crystallization: After the reaction is complete, the product solution undergoes cooling treatment to lower the temperature. At low temperatures, the product begins to crystallize, forming solid particles, while impurities remain in the solution.
Filtration: The solution resulting from freeze crystallization is filtered through a filter, separating the solid crystalline particles from the solution. Filtration helps remove residual solvents, impurities, and other solid particles.
Solid: The filtered solid particles are collected, typically forming a wet gel-like solid material.
Washing: To remove residual impurities and solvents, the solid material often undergoes a washing process. Washing can be done using appropriate solvents or water to clean the solid, ensuring its purity and quality.
Filtration: After washing, the solid material undergoes filtration again to remove solvents and other residues generated during the washing process.
Sieving: The filtered solid material may contain particles of different sizes. To obtain a consistent product specification, sieving is performed. Using suitable sieves or sieving equipment, the particles are classified according to specific sizes.
Drying: The sieved solid material typically contains a certain amount of moisture. To remove the moisture and obtain a dry product, the solid material needs to be dried. Drying can be done using hot air, vacuum, or other appropriate methods until the moisture content of the solid material meets the product requirements.
Sieving: The dried product is sieved again to ensure that the particle size and quality of the product meet the specifications.
Finished product: The sieved and dried product is considered the finished product, meeting the required purity, particle size, and other specifications.
Packaging: Finally, the finished product is packaged in suitable containers to protect its quality and extend its shelf life. Packaging is typically done in sealed containers to ensure product safety and stability.
