Diethylene glycol butyl ether (DEGBE, 2-(2-butoxyethoxy)ethanol) is the organic compound with the formula {{chem2|C4H9OC2H4OC2H4OH}}. A colorless liquid, it is common industrial solvent. It is one of several glycol ether solvents. It has low odour and high boiling point. It is mainly used as a solvent for paints and varnishes in the chemical industry, household detergents, and textile processing.{{cite book |doi=10.1002/14356007.a10_101 |chapter=Ethylene Glycol |title=Ullmann's Encyclopedia of Industrial Chemistry |date=2000 |last1=Rebsdat |first1=Siegfried |last2=Mayer |first2=Dieter |isbn=978-3-527-30385-4 }}{{cite web |title=DB Solvent (Diethylene Glycol Monobutyl Ether) |url=https://www.eastman.com/en/products/product-detail/71000140/db-solvent-diethylene-glycol-monobutyl-ether |website=Eastman |access-date=16 December 2024}}
Production and use
Diethylene glycol monobutyl ether is produced from butanol by ethoxylation, the reaction with ethylene oxide in the presence of a basic catalyst.{{Cite web |title=Archived copy |url=http://www.arb.ca.gov/consprod/regact/2010ra/degbe112345.pdf |url-status=dead |archive-url=https://web.archive.org/web/20150923173017/http://www.arb.ca.gov/consprod/regact/2010ra/degbe112345.pdf |archive-date=2015-09-23 |access-date=2015-09-02}}
