Información del producto

• Nombre: Ethyl 2-(ethoxymethylene)-3-oxobutanoate
• Marca: Biosynth
• Descripción: Ethyl 2-(ethoxymethylene)-3-oxobutanoate is an industrial chemical that is used as a precursor to acetoacetate. It is produced by the condensation of formaldehyde and ethyl acetoacetate, which yields two molecules of ethyl 2-(ethoxymethylene)-3-oxobutanoate. This reaction can be performed in three steps, with the first step involving the addition of formaldehyde and hydrazine to acetoacetate. The second step involves heating the reaction mixture until it boils, followed by cooling and filtering. The third step requires refluxing for six hours before distilling off the liquid. Ethyl 2-(ethoxymethylene)-3-oxobutanoate can also be synthesized from orthoformic acid and ethyl acetoacetate in an experiment that produces 1 mole of product for every mole of starting material.
