Introduction
Isobutanol, also known as 2-butanol. The following is an introduction to the properties, uses, preparation methods and safety information of isobutanol: 1. Properties: It is soluble in water and most organic solvents, and has strong dehydration and corrosiveness. 2. Uses: Isobutanol has a wide range of applications in industry. It is an important solvent for organic synthesis, which can be used for organic synthesis reactions and the preparation of a variety of chemical reagents. 3. Preparation method: Isobutanol can be obtained through a series of chemical reactions. Among them, the most commonly used method is prepared by the hydrogenation reaction of isobutylene. Catalyzed by a hydrogenation agent, such as nickel, isobutylene is reacted with hydrogen to produce isobutanol. 4. Safety information: Isobutanol is harmful to both people and the environment. It is a flammable liquid that explodes when in contact with an open flame, high temperatures, and oxygen. Isobutanol is irritating and corrosive, causing irritation and burns in contact with the skin, eyes, and respiratory tract. When using or storing isobutanol, care must be taken to avoid contact with fire and oxygen, and to pay attention to personal protective measures such as wearing protective gloves, goggles, and face shields. When disposing of waste, it is necessary to comply with relevant laws and regulations to avoid polluting the environment.
Application
Isobutyl alcohol (IBA, CAS 78-83-1) is a versatile 4‑carbon branched primary alcohol that serves as a key building block across multiple industries. As a high-purity solvent, it is widely used in industrial coating applications for nitrocellulose lacquers, ambient‑cured enamels, automotive coatings, and printing inks, where it reduces formulation viscosity, promotes flow and leveling, and provides excellent blush resistance. As a chemical intermediate, it is essential for the production of isobutyl acetate, isobutyl acrylate, and various plasticizers, as well as synthetic musk fragrances, fruit flavorings, and pharmaceutical compounds including anesthetics and vitamins. In personal care and cosmetics, IBA functions as a solvent and emulsifier in lotions, creams, hair care products, and perfumes, where it helps solubilize essential oils and fragrance compounds while maintaining formulation stability. It also serves as an anti‑knock fuel additive to improve gasoline octane ratings and reduce emissions, as an extraction agent in pharmaceutical manufacturing, and as an analytical reagent for chromatographic applications. Xinchem offers custom synthesis, custom chemical synthesis, and contract manufacturing of high‑purity isobutyl alcohol with flexible scaling from R&D to commercial tons.
