Packaging and shipping
4-Methyl-2-pentanone (Methyl Isobutyl Ketone, abbreviated as MIBK), with the chemical formula C₆H₁₂O, is a colorless transparent, flammable, volatile ketone solvent with a similar camphor or mint-like stimulating odor. The MIBK product provided by Anhui Yipu Chemical has strict purity control. Its core value lies in its excellent dissolving ability, moderate evaporation rate (boiling point approximately 116°C), and relatively low toxicity, making it an indispensable high-performance solvent and synthetic intermediate in multiple industries such as coatings, rubber, electronics, and medicine.




Product Description
Anhui Eapearl Chemical Co., Ltd., as a professional chemical supplier in China, fully understands the extensive application value of 4-methyl-2-pentanone (MIBK) as a high-performance medium-boiling-point solvent and key chemical intermediate in modern industry. At the same time, we are also acutely aware that MIBK is a flammable and irritating hazardous chemical, and its production, storage, transportation and use must strictly comply with safety and environmental protection regulations. We solemnly promise to strictly abide by all relevant laws and regulations, provide high-quality products, and place safety, health, environmental protection and compliance management at the core.
Product Introduction
The core value of MIBK lies in its balanced solubility and volatility, as well as its irreplaceability as a key synthetic raw material.
Key intermediate of rubber antioxidant (dominant application): MIBK is the main raw material for producing rubber antioxidant 6PPD (4020), which is an indispensable additive for radial tires. The rubber antioxidant field is MIBK’s largest consumption sector, accounting for over 40%.
High-performance coatings and ink solvents: Due to its excellent leveling property, high solubility and moderate evaporation rate, MIBK is widely used in automotive coatings (metal glitter paint, repair paint), industrial coatings, wood coatings, varnish and intaglio printing inks, significantly enhancing the gloss and printing quality of the paint film. The consumption in the surface coating field accounts for nearly 50%.
Electronic-grade precision cleaning and lithography processes: High-purity (electronic grade) MIBK is used for semiconductor wafer cleaning, photomask stripping and LCD panel cleaning, effectively removing contaminants without damaging precision components. Although it accounts for less than 8% in the electronic chemicals field, its average annual growth rate exceeds 12%, making it a high-value-added core growth point.
Pharmaceutical and pesticide extraction solvents: Used for the extraction of antibiotics (such as erythromycin), alkaloid extraction and the separation and purification of pesticide active ingredients.
Rare metal extractants and lubricant dewaxing: In the metallurgical industry, it is used for the extraction and separation of rare metals such as tantalum/nickel, zirconium/hafnium; in petroleum refining, it is used as an efficient lubricant dewaxing solvent.
