Second, the Synthetic Route we will recommend is the most important for your reference?
The reaction distillation synthesis process using direct esterification method is as follows:
Using propylene glycol methyl ether and propionic acid as raw materials, p-toluenesulfonic acid as catalyst, and ethyl propionate as azeotropic dehydration agent, direct esterification synthesis was carried out through reactive distillation.
Advantages of this method:
A. Breaking through the traditional production process of using sulfuric acid as a catalyst and benzene as an azeotropic dehydrating agent, overcoming the strong corrosiveness of sulfuric acid and the complex post-treatment problems,
B. Solved the problem of environmental and product pollution caused by aromatic dehydration agents, achieving the goal of clean production.
C. High product quality, purity greater than 99.5%, moisture less than 0.05%, and free acid content less than 0.05%
Third, what is the usage of 2-methoxy-1-methylethyl propionate? pleas see below
Because its strong solubility for polar and non-polar substances ,it is the most ideal solvent for directly replacing ethylene glycol ether acetate.
The reason is that it is suitable for solvents of various polymers in high-end coatings and inks, including amino methyl ester, vinyl, polyester, cellulose acetate, alkyd resin, acrylic resin, epoxy resin, and nitrocellulose. Among them. A New Generation of Green Ring with Excellent Performance for Propylene Glycol Methyl Ether Propionate Ester.
Propylene glycol methyl ether propionate, also known as PGMEA, is an important organic synthesis solvent. It is synthesized by the reaction of propylene glycol methyl ether and propionic anhydride, and has many unique properties and wide application fields.
Firstly, 1-Methoxy-2-propanol propanoate plays an important role in the electronics industry. Due to its low surface tension, strong solvent strength, and good debonding ability, it is widely used in the cleaning and manufacturing processes of semiconductor chips. It can effectively remove dirt and residues on the surface of the chip, ensuring the quality and stability of the chip. In addition, propylene glycol methyl ether propionate can also be used as a diluent for photoresist, helping to improve the adsorption performance and development effect of the photoresist, thereby achieving more accurate pattern transfer.
Secondly, 1-Methoxy-2-propanol propanoate also has important applications in the paint industry. Due to its low viscosity and good volatility, it is widely used as a solvent and diluent in various paint formulations. Whether it is water-based or oil-based coatings, propylene glycol methyl ether propionate can provide good solubility and flowability, ensuring that the coating is uniform and easy to apply. In addition, it can also be used as a stabilizer for coatings, helping to improve their adhesion and durability.
1-Methoxy-2-propanol propanoate is also widely used in cosmetics and personal care products. It has good solubility and permeability, which can help other ingredients better absorb on the skin and improve the effectiveness of the product. At the same time, it also has good gentleness and low irritation, suitable for use on various types of skin. Therefore, in skincare, makeup, and personal care products, propylene glycol methyl ether propionate is often used as a diluent, solvent, and thickener.
