Isobutanol (IBA) is a colorless, transparent liquid with a distinctive odor. It has a boiling point of 107.2°C, a melting point of -108.9°C, and a density of 0.806 g/cm³. Isobutanol is miscible with water but immiscible with hydrocarbon solvents. Additionally, it exhibits low viscosity and surface tension. At ambient temperature, isobutanol exists as a colorless liquid with a low boiling point and relatively high vapor pressure.
Storage conditions for isobutanol (IBA) are as follows:
- Storage Environment: IBA should be stored in a cool, well-ventilated warehouse, away from ignition sources and heat. Warehouse temperature should not exceed 30°C.
- Container Requirements: Keep containers tightly sealed to prevent leakage and vapor diffusion.
Safety Measures:
- Warehouses must employ explosion-proof lighting and ventilation systems. Use of spark-producing machinery or tools is prohibited.
- IBA must be stored separately from incompatible substances such as oxidizers and acids; mixed storage is strictly prohibited.
- Storage areas must be equipped with emergency leak response equipment and suitable containment materials.
Additional Precautions:
- IBA is flammable. Its vapors can form explosive mixtures with air and may ignite or explode upon contact with open flames or intense heat.
- Operate in strict compliance with safety protocols, including wearing protective gear and preventing static electricity buildup.
Is Isobutyl Alcohol (2-Methyl-1-Propanol) Toxic?
Isobutyl Alcohol (CAS 78-83-1) possesses certain toxicity and is harmful to humans.
- Skin Contact with Isobutyl Alcohol: Remove contaminated clothing and thoroughly rinse skin with soap and water.
- Eye contact with isobutanol: Immediately lift eyelids and flush thoroughly with copious amounts of running water or saline solution for at least 15 minutes. Seek medical attention.
- Inhalation of isobutanol: Move the affected person to fresh air immediately. Keep the airway clear. If breathing is difficult, administer oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention.
- Ingestion of isobutanol (IBA): Drink plenty of warm water and induce
