Basic Information
Product Name: Acetyl tributyl citrate
CAS Number: 77-90-7
Alias: ATBC, Tributyl O-acetylcitrate
Molecular Formula: C20H34O8
Molecular Weight: 402.48 g/mol
IUPAC Name: Tributyl 2-acetylpropane-1,2,3-tricarboxylate
Structural Information
- Structure Type: Ester compound, acetylated citrate derivative
- Structural Features: Based on citric acid skeleton, three carboxyl groups form butyl esters and one hydroxyl group is acetylated. The molecular structure endows it with excellent plasticizing performance, low volatility and good compatibility.
Physical & Chemical Properties
- Appearance: Colorless to pale yellow clear oily liquid
- Odor: Odorless or slight characteristic odor
- Melting Point: ?60 °C
- Boiling Point: 343 °C (760 mmHg)
- Density: 1.045–1.055 g/mL (20 °C)
- Refractive Index: 1.441–1.445 (20 °C)
- Solubility: Insoluble in water; miscible with ethanol, ether, benzene, vegetable oil and most organic solvents
- Stability: Stable under normal temperature and sealed conditions. Resistant to light, heat and hydrolysis. Incompatible with strong oxidants and strong alkalis.
Synthesis & Applications
Synthesis Method
Produced by two-step reaction: first esterification of citric acid and butanol to obtain tributyl citrate, then acetylation with acetic anhydride. The crude product is neutralized, washed and distilled to get high-purity finished product.
Main Applications
- Plastic Industry: Environmentally friendly primary plasticizer for PVC, cellulose resin and rubber, widely used in food-contact and medical plastic products.
- Packaging Material: Applied for plastic film, food packaging and toy materials due to non-toxic property.
- Cosmetics & Daily Chemicals: Used as emollient and solvent in cosmetics and personal care products.
- Coating Industry: Additive for water-based coatings and adhesives to improve flexibility.
