Acetonitrile
ELRASATM – ACNT
Acetonitrile is a colorless, volatile liquid with a sweet, ether-like odor. It is widely used as a solvent in the pharmaceutical industry, particularly in the synthesis of vitamins and antibiotics. Acetonitrile is also employed in the production of perfumes, rubber products, and as a solvent in the purification of butadiene. Its high polarity and ability to dissolve a wide range of compounds make it a valuable solvent in chemical analysis and chromatography.

Processing Methods & Reference Formulations
A. Fragrance Spray
Incorporate Acetonitrile in the final solvent blending phase at room temperature to prevent volatility loss. Ensure all fragrance components are pre-dissolved or solubilized.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Deionized Water | 71% |
| Fragrance Blend | 1.5% |
| Acetonitrile | 12% |
| Acetone | 5% |
| Propylene Glycol n-Propyl Ether | 10% |
B. Lithium-Ion Battery Electrolyte
Acetonitrile (ACN) can be used at 10–30% as a co-solvent to enhance ionic conductivity due to its high dielectric constant and low viscosity.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) | 20% |
| Acetonitrile | 15% |
| 1,1,2,2-Tetrafluoro-1-(trifluoromethoxy)ethane (low-freezing co-solvent) | 60% |
| Performance-enhancing additives (e.g., methyl trifluoroethyl carbonate, vinylene carbonate) | 5% |
C. Metal-Cleaning Solvent
Acetonitrile is highly volatile and should be added during the final blending stage at room temperature (under 25°C) to minimize solvent loss and vapor accumulation. Acetonitrile is hygroscopic, formulate in a moisture-free environment or include a desiccant or drying step to prevent water pickup.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Acetonitrile | 92% |
| Acetylacetone | 4% |
| Triethylamine | 4% |
Dosing Guidelines
