Products Dibasic ester (DBE)
PRODUCT NAME
Dibasic ester (DBE)
Dibasic ester (DBE) is a refined mixture of dimethyl esters primarily derived from
three dicarboxylic acids: adipic, glutaric, and succinic acids. It is widely valued in the
chemical industry as a high-performance, eco-friendly solvent due to its low toxicity,
high boiling point, and ready biodegradability.
Chemical Composition & Properties
-
Boiling Range:
High boiling point, typically between 196°C and 225°C (385–437°F).
-
Solubility:
Readily soluble in alcohols, ketones, and ethers, but only slightly soluble in water. -
Safety Profile:
Non-corrosive, non-flammable (high flash point around 100°C), and non-carcinogenic. -
Components:
Typically consists of dimethyl glutarate (55–65%), dimethyl adipate (10–25%), and dimethyl succinate (15–25%). -
Physical State:
A clear, colorless liquid with a mild, fruity odor
Primary Industrial Applications
Dibasic ester serves as a versatile alternative to traditional hazardous solvents like
methylene chloride or acetone.
-
Paints and Coatings:
Used as a high-boiling solvent to improve flow and leveling in industrial coatings and as a coalescing agent in water-based paints. -
Cleaning Agents:
Highly effective in paint strippers, graffiti removers, and industrial degreasers due to its ability to dissolve hardened resins and polar substances. -
Chemical Intermediates:
Acts as a raw material for producing plasticizers, polyester polyols for polyurethanes, and specialty resins. -
Agrochemicals:
Serves as a carrier or solvent for active ingredients in pesticides and insecticides.
