Use of DIBC
Diisobutyl ketone (DIBK) is a transparent liquid with a distinct odor and a high boiling point. It is an heavy-end byproduct of producing MIBK. DIBK is used in many applications such as nitrocellulose lacquers, synthetic resins, coatings and stains, paint strippers, leather finishings, adhesives, printing and coating inks, cleaning and degreasing, Flavors and fragrances, solvent and re-crystallization aid for pharmaceuticals, mining, and as a chemical intermediate. DIBK has good activity for many synthetic resins including nitrocellulose, rosin esters, phenolics, hydrocarbons, alkyds, polyesters, and acrylics. It is useful as a retarder solvent to improve flow and minimize humidity blushing. The low density and low surface tension of DIBK enables formulators to develop high-solids coatings with low VOC content and excellent flow and leveling properties. DIBK has excellent viscosity reduction for and reduces surface tension in high solid's coatings. It has a good volume-to-weight advantage over other classes of solvents used in coatings. It is a non-HAP (Hazardous Air Pollutant) solvent
Chemical properties of DIBC
Diisobutyl carbinol (DIBK) is a colorless oily liquid with a slight, ether, fermented, fruity and sweet jackfruit or peppermint-like odor. Its boiling point is 169°C and the flash point is 45°C. It is insoluble in water, but soluble in ethanol and oils.
Its natural products are found in Congke wine, grape wine, etc.
Uses of DIBC
It is used as a food spice. It is mainly used to make flavors of jackfruit, banana, orange juice, egg fruit, tropical fruit, rum, and konjac.
This product is mainly used as an organic solvent and can also be used for organic synthesis. It can dissolve cellulose acetate, nitrocellulose, polystyrene, vinyl, wax, varnish, natural resin, and raw rubber. Due to its high boiling point and slow evaporation rate, it can be used as a solvent for nitro spray paints, vinyl resin coatings, and other synthetic resin coatings. It is also an intermediate for certain drugs and insecticides.
It is used as an organic synthesis intermediate.
