English description(英文原文,共 1171 字符)
Product Name:Dibutyl maleate
English Name:Dibutyl maleate
CAS No.:105-76-0
Aliases:Maleic acid dibutyl ester, Dibutyl (2Z)-2-butenedioate, (Z)-2-Butenedioic acid dibutyl ester
Molecular Formula:C12H20O4
Physical Properties:Colorless transparent liquid. Density (20°C): 0.9964 g/cm³; freezing point: < -85°C; boiling point: 280.6°C; flash point: 140.5°C; refractive index (20°C): ca. 1.444. Insoluble in water; soluble in ethanol, diethyl ether and other organic solvents. Molecular weight: 228.29.
Uses:As an internal plasticizer, it can copolymerize with monomers such as vinyl chloride, vinyl acetate, styrene, or acrylic esters. The copolymers are used in coatings, films, adhesives, paper treatment agents, pigment fixing agents, impregnating agents, dispersants, lubricants, etc. In polyvinyl chloride products, it imparts softness, smoothness, and good transparency, though its thermal volatility is relatively high.
Technical Specifications:
Colorless transparent liquid appearance
Color (APHA) ≤ 30
Acid value (mg KOH/g) ≤ 0.5
Purity (content) ≥ 98%
Packaging: 200 kg/drum (plastic drum or galvanized drum); store in a cool, dry, well-ventilated place
