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 tonsteam tonfurfural (-1) and facilitate the product recovery through a simple liquid/liquid separation of the condensate into a water-rich and a furfural-rich phase.
用HCl/蒸汽气流汽提甘蔗渣并将流出物冷凝为水/糠醛/乙酸时，分别以约60%和90%的摩尔产率生成糠醛和乙酸。反应动力学对糠醛为一级，对HCl为0.5级。提出了一种反应流出物完全循环的工艺概念，以将能源需求降低至<10吨蒸汽/吨糠醛，并通过将冷凝物简单液液分离为富水相和富糠醛相来促进产物回收。
