Structural formula:
1. Product Property
Ethylene glycol butyl ether is a clear, colorless liquid with a mild, pleasant odor. It is miscible with most organic solvents and water, offering excellent solvency for resins, oils, and greases. With a boiling point around 170–172°C and low vapor pressure, it is widely used in formulations requiring slow evaporation and high boiling points. It also has good stability and low toxicity under normal handling conditions

3. Application Scope and Usage
Ethylene glycol butyl ether is widely used as a solvent in coatings, paints, inks, and cleaning agents due to its strong solvency and slow evaporation rate. It is also found in hydraulic fluids, cosmetics, and household cleaners. In industrial applications, it serves as a coupling agent in water-based formulations and as a coalescing aid in latex paints. Its ability to dissolve both polar and non-polar substances makes it valuable in diverse chemical processes
4. Package and Storage
Ethylene glycol butyl ether is typically packed in 200-liter steel drums or IBC totes (1000 liters), depending on customer requirements. It should be stored in a cool, dry, and well-ventilated area, away from direct sunlight, heat, and incompatible materials such as strong oxidizers and acids. Containers must be tightly sealed to prevent moisture ingress and evaporation. Proper handling and storage ensure product stability and shelf life of up to two years under recommended conditions
