Chemical Properties

Chemical Formula: Dibasic esters are typically a mixture of dimethyl esters of adipic, glutaric, and succinic acids.
Molecular Weight: Varies based on composition, typically around 160-200 g/mol.

Physical Properties

Appearance: Clear, colorless to slightly yellow liquid.
Odor: Mild, fruity odor.
Density: 1.05 to 1.10 g/cm³ at 25°C (77°F).
Refractive Index: 1.415 to 1.425 at 20°C (68°F).
Boiling Point: Typically in the range of 190°C to 225°C (374°F to 437°F), depending on the specific mixture.
Melting Point: Generally low, around -20°C to -30°C (-4°F to -22°F).
Flash Point: Approximately 100°C to 110°C (212°F to 230°F).
Viscosity: Low to moderate, around 2 to 4 centipoises at 25°C (77°F).

Solubility

Water Solubility: Slightly soluble in water.
Solubility in Other Solvents: Miscible with most organic solvents, such as alcohols, ketones, and hydrocarbons.

Environmental and Safety

Biodegradability: Readily biodegradable.
Toxicity: Low toxicity; however, prolonged exposure may cause irritation.
Safety: Generally considered to be of low hazard, but proper handling and storage are necessary to avoid skin and eye contact.

Applications

Solvents: Used in paints, coatings, inks, and adhesives due to their excellent solvency and low volatility.
Plasticizers: Act as plasticizers in various polymer formulations.
Cleaning Agents: Utilized in industrial cleaning applications for their effective degreasing properties.
Chemical Intermediates: Used in the synthesis of other chemicals and materials.
