    摘要: A process for producing isoprene in good yield is provided. The process is characterized in that an alkyl tertiary butyl ether and a formaldehyde source are fed, together with water, into a acidic aqueous solution continuously or intermittently while maintaining the reaction pressure in an adequate range and at the same time distilling off the product isoprene, unreacted starting materials, isobutene and tertiary butanol, together with water, from the reaction zone.
