Packaging and shipping
tert-Butanol (TBA), also known as 2-methyl-2-propanol, is a colorless, flammable liquid or crystalline solid with a camphor-like odor. It has the molecular formula C₄H₁₀O and is miscible with water, ethanol, ether and many organic solvents. It features high stability, low volatility and good solubility, making it a widely used industrial solvent, extractant and chemical intermediate.
It is mainly used in pharmaceuticals and cosmetics as a solvent and cosolvent for active ingredients, helping to improve drug stability and absorption. In organic synthesis, it serves as a key raw material for producing antioxidants, flavors, fragrances and synthetic resins. It is also widely applied in coatings, cleaning agents, and as a denaturant for ethanol.
In addition, tert-butanol is used in laboratory and industrial extraction processes due to its good phase separation and solubility properties. As a flammable chemical, it should be stored in a cool, well-ventilated area away from heat, open flames and strong oxidizers. With high purity and stable performance, tert-butanol is widely used in fine chemical, pharmaceutical and manufacturing industries.
Product Description
Tert-Butanol(TBA) , a high-purity tertiary alcohol, is a colorless, flammable liquid or crystalline solid with a characteristic camphor-like odor.
It exhibits excellent solubility in water, alcohols, ethers, and most organic solvents, along with high chemical stability and low corrosiveness.
TBA is known for its high octane value, low toxicity, and good volatility, making it a versatile industrial solvent and chemical intermediate.
It is typically packaged in sealed, explosion-proof steel drums (160kg/200L) or ISO tanks to ensure safety and prevent leakage.
All packaging complies with international hazardous material transport standards, with clear labeling for secure storage and handling.
TBA is widely used in multiple industries due to its unique properties. In the petrochemical sector, it serves as a key octane booster for gasoline and a raw material for
producing methyl tert-butyl ether (MTBE) and ethyl tert-butyl ether (ETBE). As a solvent, it is applied in coatings, inks, adhesives, and cleaning agents, dissolving resins and
improving formulation stability. In organic synthesis, TBA acts as an intermediate for manufacturing perfumes, pharmaceuticals, and plasticizers. Additionally, it functions as a denaturant
for ethanol and a dehydrating agent in laboratory applications. Its high reactivity and compatibility make TBA an essential chemical in modern industrial production.
