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. Epoxides are very reactive due to ring strain and diepoxybutane contains two of these groups, so it is highly reactive, more than other ethers. It is hydrophilic, very flammable and easily ignited by heat or sparks.

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