Furfural and acetic acid are produced with approximately 60 and 90 mol % yield, respectively, upon stripping bagasse with a gaseous stream of HCl/steam and condensing the effluent to water/furfural/acetic acid. The reaction kinetics is 1 st order in furfural and 0.5 th order in HCl. A process concept with full recycling of the reaction effluents is proposed to reduce the energy demand to <10 ton steam ton furfural −1 and facilitate the product recovery through a simple liquid/liquid separation of the condensate into a water‐rich and a furfural‐rich phase.
