2-Butoxyethanol Powder is a colorless and flammable liquid with moderate ether odor.
2-Butoxyethanol Raw Materials is an excellent solvent. It is also an excellent surfactant to remove oil and dirt from the surface of metal, fabric, glass. It is also an excellent surfactant to remove oil and dirt from the surface of metal, fabric, glass, plastic, etc.
2-Butoxyethanol Raw Materials is widely used in paint, ink, leather, printing and dyeing, medicine, electronic industry.
2-Butoxyethanol CAS 111-76-2 is widely used in paint, ink, leather, printing and dyeing, medicine, electronic industry. 2-Butoxyethanol contains both ether bonds and hydroxyl groups in its molecules, which makes it soluble in organic molecules, synthetic or natural polymer compounds, and also miscible with water or water-soluble compounds to varying degrees.
2-Butoxyethanol CAS 111-76-2 is one of the important industrial derivatives of epoxy compounds and is an extremely important fine chemical. The former is lipophilic and can dissolve hydrophilic compounds, and the latter is hydrophilic and can dissolve hydrophilic compounds, so it has strong solvency ability and is known as "universal solvent". It is called "universal solvent".
Application/Function of 2-Butoxyethanol Powder.
2-Butoxyethanol Powder Used as a solvent for paints and inks, a component of metal cleaners and a raw material for dye dispersants.

2-Butoxyethanol CAS 111-76-2 is used as a solvent for nitrocellulose, spray paint, quick-drying paint and varnish, as a solvent for paints and inks and as a raw material for dye dispersant.
Production method of 2-Butoxyethanol Powder.
2-Butoxyethanol Raw Materials is obtained by addition of n-butanol to ethylene oxide. The n-butanol was added to the ether solution of boron trifluoride at 20°C and ethylene oxide was passed through with stirring. The temperature automatically increased as the reaction proceeded, and was left for three days after the temperature dropped. The crude product was obtained by neutralizing with potassium hydroxide methanol solution to pH=8. Add a little p-aminophenol to the crude product and then fractionate the product at 166-170℃ to obtain the finished product. Industrial production can be carried out by non-catalytic reaction at high temperature and pressure (reaction temperature 180-250°C, pressure 2.1-4.6 MPa) for 6 h. It can also be carried out at near atmospheric pressure and lower temperature using alkali catalyst.
Butanol is mixed with boron trifluoride-ether complex, and then the reaction is carried out at 25-30 °C by passing ethylene oxide and increasing the temperature to 80 °C. After the reaction, the excess butanol is recovered, neutralized with alkali, distilled and fractionated to give the finished product of ethylene glycol monobutyl ether.
