| Formula: C4H10O CAS: 78-83-1 Description: Isobutanol is a clear, mobile, neutral liquid with a characteristic odor. It is miscible with all common solvents, e.g., alcohols, ketones, aldehydes, ethers, glycols, and aromatic and aliphatic hydrocarbons, but is only sparingly soluble in water. Applications: A large part of the isobutanol produced is converted into derivatives(primarily esters) for use as solvents in the coatings industry. Isobutanol is an eminently suitable solvent for acid-curable lacquers and baking finishes derived from urea (Plastopal), melamine (Luwipal), or phenolic resins. When added even in small proportions to alkyd resin paints, isobutanol reduces the viscosity, and thus improves the brushability and flow. Diisobutyl phthalate (DIBP) is an established plasticizer for plastics, dispersions and rubber mixes. Other isobutyl esters of dicarboxylic acids, e.g., adipic, azelaic and sebacic acids, display good properties in this application, but economic considerations preclude their use.
