Diethylene glycol dibutyl ether

Diethylene glycol dibutyl ether (CAS 112-73-2), commercially known as Dibutyl Carbitol, is a high-boiling glycol ether solvent.

Where is Diethylene glycol dibutyl ether used?

• Coatings and polymers: coalescing solvent and plasticizer carrier, improving film formation
• Curing and cross-linking: reaction medium and catalyst solvent where thermal stability at elevated temperatures is required
• Printing inks and electronic pastes: high-boiling carrier controlling rheology and drying profiles
• Extraction and separation: selective solvency for liquid-liquid extraction of metal ions and organic compounds at industrial scale
• Its low volatility and strong solvency make it a carrier in formulations.

Good to know: Controlled evaporation and compatibility with resins or active components are critical procurement considerations.

Commercial specifications

• Clear liquid in drum, IBC, and bulk quantities
• Technical grade, purity typically 98% or higher
• High-purity grades for electronic and specialty chemical applications, with trace contaminant limits tightly controlled
