Diepoxybutane (also known as butane diepoxide, butadiene diepoxide, or 1,2:3,4-diepoxybutane) is an epoxide which is a colorless liquid at room temperature.[3] It is therefore highly reactive, more than other ethers. An epoxide is a cyclic ether that contains a three atom ring that comes close to an equilateral triangle. The primary structure of an epoxide contains two carbon atoms and a hydrocarbon attached to an oxygen atom. It polymerizes in the presence of catalysts or when heated.[4] It’s hydrophilic, very flammable and easily ignited by heat or sparks.[3]

Diepoxybutane is used as a chemical intermediate, as a curing agent for polymers, as a cross-linking agent for textiles, and as a preservative.[2]
