采用连续流动反应装置，研究了D-葡萄糖在水中反应生成5-羟基乙基呋喃甲醛(5-HMF)、1，2，4-苯三酚(BTO)和糠醛的反应。在最高温度和压力条件下，呋喃甲醛的产率最高，压力从40增加到70，80 Mpa加强了5-HMF的脱水反应，但也促进了5-HMF的水解，导致BTO的产生，从而导致5-HMF的产率较低(低于10%)。值得注意的是，在400℃下增加水密度，5-HMF的脱水反应和5-HMF的水解都得到了加强。(C)2006 Elsevier B.V.
Reaction Of D-glucose in water to yield 5-hydroxyinethylfurfural (5-HMF), 1,2,4-benzenetriol (BTO) and furfural was studied at high temperatures (up to 400 degrees C) and high pressures (up to 80 MPa) using a continuous flow reactor. Maximum temperature and pressure conditions gave maximum furfural yield, Increasing pressure from 40 to 70 and 80 MPa enhanced dehydration reactions to 5-HMF, but also enhanced hydrolysis of 5-HMF leading to the production of BTO and thus lead to lower yields of 5-HMF (below 10%). Remarkably, the dehydration reaction to 5-HMF and the hydrolysis of 5-HMF were both enhanced by the increase in water density at 400 degrees C. (c) 2006 Elsevier B.V. All rights reserved.
