Introduction
Butyl acetate.
Density 0.88.
Boiling point 124-128 degrees Celsius.
Freezing point -76 degrees Celsius.
It is an excellent organic solvent, clear and colorless in appearance, flammable. Cellulose acetate butyrate, ethyl cellulose, chlorinated rubber, polystyrene, natural tree resin, resin and so on have good solubility. Widely used in nitrocellulose cleaning, solvent for artificial leather, fabric and plastic processing, various petroleum processing and pharmaceutical extracts.
n-Butyl Acetate: Properties and Industrial Applications
Table 1: Key Physical and Chemical Properties
| Property | Value | Significance |
|---|---|---|
| Molecular Formula | C₆H₁₂O₂ | Determines solvent characteristics |
| Molecular Weight (g/mol) | 116.16 | Affects volatility & formulation balance |
| Boiling Point (°C) | 126 | Influences drying time in coatings |
| Melting Point (°C) | -78 | Ensures liquid state in most conditions |
| Density (g/cm³) | 0.88 | Important for solvent blending |
| Flash Point (°C) | 22 (closed cup) | Indicates flammability risk |
Table 2: Major Industrial Applications
| Industry | Application | Function |
|---|---|---|
| Coatings & Paints | Lacquers, enamels, thinners | Provides smooth flow & fast evaporation |
| Inks | Printing & flexographic inks | Enhances pigment dispersion & drying |
| Adhesives | Rubber & resin-based adhesives | Adjusts viscosity & improves bonding |
| Pharmaceuticals | Extraction & purification | Acts as a process solvent |
| Cleaning Agents | Degreasers & surface cleaners | Effective for oil & grease removal |
Table 3: Comparison with Common Solvents
| Solvent | Advantages | Disadvantages |
|---|---|---|
| n-Butyl Acetate | Balanced evaporation rate, low toxicity | Moderate flammability |
| Acetone | Fast drying, low cost | Highly flammable, strong odor |
| Ethyl Acetate | Pleasant odor, biodegradable | Faster evaporation (less controllable) |
| Toluene | Strong solvency, cheap | High toxicity, environmental concerns |
Table 4: Safety & Regulatory Information
| Parameter | Value | Regulatory Status |
|---|---|---|
| OSHA PEL (8-hr TWA) | 150 ppm | Workplace exposure limit |
| LD50 (Oral, Rat) | 13.000 mg/kg | Low acute toxicity |
| VOC Classification | Yes | Regulated in paint/coatings industry |
| REACH Compliance | Registered | Approved for EU use |
n-Butyl acetate is a widely used solvent valued for its moderate evaporation rate, effective solvency, and relatively low toxicity. It plays a key role in coatings, inks, and adhesives, offering a safer alternative to more hazardous solvents like toluene. Proper handling is required due to its flammability.
