Methyl Isobutyl Ketone (MIBK), or 4-Methyl-2-pentanone, is a workhorse solvent and chemical intermediate widely used across industries. While its utility is undeniable, a thorough understanding of its properties, coupled with strict adherence to safety and handling protocols, is paramount for all industrial users. This ensures both the integrity of the product and the safety of personnel and the environment.
Key Physical and Chemical Properties of MIBK
MIBK (CAS: 108-10-1) presents as a colorless to light yellow oily liquid. Its molecular formula is C₆H₁₂O, with a molecular weight of approximately 100.16 g/mol. Key properties include a relatively low flash point of around 13.3°C, classifying it as a flammable liquid. Its boiling point is approximately 116.5°C, and it has a melting point of -84°C. The vapor pressure is notable at 18.2 mmHg at 25°C, indicating significant volatility. Its index of refraction is 1.393. These characteristics dictate how it should be stored and handled.
Safety First: Handling and Storage Recommendations
Given its flammability, MIBK must be stored in a cool, well-ventilated place, away from heat sources, sparks, and open flames. Containers should be kept tightly closed to prevent vapor escape. Inhalation of MIBK vapors can cause drowsiness or dizziness and may be harmful, so adequate ventilation or respiratory protection is essential when working with it. Eye irritation is also a concern, necessitating the use of appropriate eye protection. Repeated exposure can lead to skin dryness or cracking, so gloves are recommended.
The Importance of Purity and Sourcing Decisions
When you decide to buy 4-Methyl-2-pentanone, ensuring it meets high purity standards (e.g., ≥99.0% assay) is critical, especially for applications in chemical synthesis or sensitive coating formulations. As a manufacturer and supplier, we focus on delivering consistently high-quality MIBK. Understanding your requirements, whether for bulk purchase in 200 kg drums or specific packaging needs, is part of our service. Competitive MIBK price is always a consideration for our clients.
For any industrial user looking to source Methyl Isobutyl Ketone, understanding these properties and safety guidelines is crucial.
