Molecular Formula: C??H??O?

Molecular Weight: 228.28 g/mol

Classification: Organic ester, unsaturated dicarboxylic acid ester, plasticizer, organic synthesis intermediate, fine chemical, copolymer monomer, coating auxiliary

Physical & Chemical Properties

Appearance: Colorless to pale yellow transparent oily liquid, with an ester-like odor; stable under normal conditions, incompatible with strong oxidizing agents, acids and bases; flammable, slightly hygroscopic; toxic to aquatic organisms

Density: 0.988-0.996 g/mL (25℃, lit.); refractive index n??/D 1.4454 (lit.); LogP: 2.7; PSA: 52.6; viscosity: 4.76-7 mPa·s (25℃)

Melting Point: < -80℃ (lit.); approx. -85℃

Boiling Point: 280.6℃ (lit., atmospheric pressure); 161℃ (24 mmHg); no obvious decomposition before boiling

Solubility: Slightly soluble in water (0.05% at 25℃, 0.173 g/L at 20℃); miscible with most organic solvents, partially soluble in benzene and chloroform; forms an azeotrope with 98.4% water (azeotropic point 99.9℃)

Purity: ≥95.0% (industrial grade, GC); ≥98.0% (analytical grade); ≥99.0% (high-purity grade)

Storage Condition: Sealed, cool and dry place at room temperature (15℃ or below is recommended), protected from light; keep container tightly closed; avoid high temperature, open flame and contact with oxidizing agents, acids and bases; store in a well-ventilated warehouse, separate from incompatible substances; avoid releasing into the environment

Main Uses

Plasticizer Field: Widely used as an internal plasticizer for aqueous dispersions of copolymers with vinyl acetate, polyvinyl chloride (PVC) and methyl acrylic resins; improves the flexibility and processability of polymers
Organic Synthesis Field: Serves as a key intermediate for organic synthesis, undergoes addition reactions on double bonds (such as Diels-Alder reaction, Michael addition reaction); used in the synthesis of surfactants (such as succinic acid dialkyl ester sulfonate), coatings, adhesives, sealants and elastomers
Industrial Auxiliary Field: Applied in petroleum industry, textile, plastic and papermaking industry as impregnant, dispersant and lubricant; used as a raw material for synthetic resins and coatings
Other Fields: Used as a raw material for the production of efficient insecticides (such as malathion); used as a gas chromatographic stationary liquid for the separation and analysis of halides and esters; used as a copolymer monomer to prepare modified polymers
