BDO
Chemical Properties | 1,4-butanediol (1,4-BD) is a colorless, viscous liquid derived from butane by placement of alcohol groups at each end of its molecular chain and is one of four stable isomers of butanediol.the hydroxyl function of each end group of the Butanediol reacts with different mono- and bifunctional reagents: for example with dicarboxylic acids to polyesters, with diisocyanates to polyurethanes, or with phosgene to polycarbonates. 1.4-Butanediol (BDO) is a high-quality intermediate. BDO and its derivatives are widely used for producing plastics, solvents, electronic chemicals and elastic fibers. Additionally BDO is also a building block for the synthesis of polyesterpolyols and polyetherpolyols. BASF is the most significant producer of 1,4-Butanediol and its derivatives worldwide. |
Uses |
|
Uses | butylene glycol is a solvent with good antimicrobial action. It enhances the preservative activity of parabens. Butylene glycol also serves as a humectant and viscosity controller, and to mask odor. |
Uses | 1,4-Butanediol is used to produce polybutyleneterephthalate, a thermoplastic polyester;and in making tetrahydrofuran, butyrolactones,and polymeric plasticizers. |
Production Methods | Methods of manufacturing: The most prevalent 1,4-BD production route worldwide is BASF's Reppe process, which reacts acetylene and formaldehyde. Acetylene reacts with two equivalents of formaldehyde to form 1,4-butynediol, also known as but-2-yne- 1,4-diol. Hydrogenation of 1,4-butynediol gives 1,4-butanediol. 1,4-BD is also made on a large industrial scale by continuous hydrogenation of the 2-butyne- 1,4-diol over modified nickel catalysts. The one-stage flow process is carried out at 80 - 160 deg C and 300 bar. Mitsubishi uses a three-step process: (1) the catalytic reaction of butadiene and acetic acid yields 1,4-diacetoxy-2-butene; (2) subsequent hydrogenation gives 1,4-diacetoxybutane; and (3) hydrolysis leads to 1,4-butanediol. |

General Description | Odorless colorless liquid or solid (depending upon temperature). |
Air & Water Reactions | Highly flammable. 1,4-Butanediol is hygroscopic. Water soluble. |
Reactivity Profile | 1,4-Butanediol is heat and light sensitive. 1,4-Butanediol reacts with acid chlorides, acid anhydrides and chloroformates; reacts with oxidizing agents and reducing agents. 1,4-Butanediol is incompatible with isocyanates and acids; also incompatible with peroxides, perchloric acid, sulfuric acid, hypochlorous acid, nitric acid, caustics, acetaldehyde, nitrogen peroxide and chlorine. |
