FAQ - Technical & Supply Chain
-
Q:
What is n-Butyl Alcohol mainly used for?
A: n-Butyl Alcohol is mainly used as an industrial solvent in coatings, paints, inks, extraction systems, and downstream butyl derivative manufacturing. It is selected where controlled solvency and process compatibility are required. -
Q:
Are n-Butanol, 1-Butanol, and n-Butyl Alcohol the same substance?
A: Yes. n-Butanol, 1-Butanol, and n-Butyl Alcohol are common names for the same substance listed under CAS 71-36-3. -
Q:
Is this product better classified as an industrial solvent rather than a specialty additive?
A: Yes. n-Butyl Alcohol is best classified as an industrial solvent and chemical raw material for formulation and processing systems rather than as a specialty additive or finished end-use product. -
Q:
What specifications should buyers confirm before ordering n-Butyl Alcohol?
A: Buyers should confirm assay or purity, water content, acidity, appearance, and packaging requirements. COA can be supplied to support grade confirmation and procurement review. -
Q:
What evaporation rate and solvency characteristics does n-Butyl Alcohol offer?
A: n-Butyl Alcohol has a moderate evaporation rate and is classified as a slow-evaporating solvent. Its evaporation rate is approximately 0.4 (n-BuAc=1) making it suitable for coatings and inks requiring controlled drying. It is miscible with most organic solvents and has a solubility of 80 g/L in water. Its solvency properties make it effective as an active solvent in nitrocellulose, acrylic, and epoxy resin formulations. -
Q:
How should n-Butyl Alcohol be handled considering its flammability classification?
A: n-Butyl Alcohol has a flash point of 35°C, classifying it as a flammable liquid (Class 3). It should be stored away from heat sources, open flames, oxidizing agents, and reactive metals such as aluminum and copper. Explosion-proof equipment is recommended in processing areas. Grounding and bonding during transfer help prevent static discharge. Adequate ventilation is essential to keep vapor concentrations below the lower explosive limit of 1.45%.
