Butyl Diglycol (DEGBE)

What is Butyl Diglycol (DEGBE)?

Butyl Glycol, also known as Diethylene Glycol Butyl Ether (DEGBE), is a colorless and slightly odorous glycol ether with the chemical formula C8H18O3.

• It has very low volatility and, thanks to this feature, maintains its effectiveness in long-term applications.
• It is water-soluble and easily mixes with different solvents.
• It is an excellent solvent and dispersant, making it the preferred choice in many industries.

However, as it may be harmful to human health, appropriate safety measures must be taken during use and storage.

How is Butyl Diglycol Produced?

1. Butyl Monoethyl Glycol Production
   • Butyl alcohol and ethylene oxide are subjected to an esterification reaction to produce butyl monoethyl glycol.
2. Oxidation Stage
   • Butyl monoethyl glycol is oxidized using nitric acid and hydrogen peroxide.
   • This reaction results in the formation of butyl diglycol.
3. Treatment Process
   • The product obtained is purified using liquid-liquid extraction, vacuum distillation, and fractional crystallization methods.

The resulting high-purity butyl diglycol is then prepared for industrial use.
