Diketene Market is forecast to reach $706 million by 2025, after growing at a CAGR of 3.5% during 2020-2025, owing to the extensive characteristics of diketene such as highly reactive building blocks, light-colored liquid, non-hygroscopic properties, and more. Diketene is an organic compound formed by dimerization of ketene and is slightly soluble in aliphatic hydrocarbons such as hexane, octane, cyclohexane, and methylcyclohexane. Also, diketene is often used in a reaction with alcohol in presence of an acid catalyst to prepare acetoacetic acid.
