在间歇式反应器中在110-200 ℃的温度下研究了在水中糠醇转化为4-羟基环己基-2-烯酮（4-HCP）、聚合物和乙酰丙酸（LA）的动力学。这些酸催化的反应在高温下由水的自解离形成的氢离子催化。在180-200 ℃的温度和5-10分钟的反应时间下，获得了大于50摩尔%的4-HCP产率。建立了描述实验数据的动力学模型。主反应和副反应的表观活化能值非常相似，这意味着4-HCP形成的选择性与温度无关。这表明，在高温下进行糠醇转化为4-HCP而不改变选择性是有吸引力的。(C)2013年韩国工业与工程化学学会。Elsevier B. V.出版，保留所有权利。
The kinetics of furfuryl alcohol conversion to 4-hydroxycyclopent-2-enone (4-HCP), polymers and levulinic acid (LA) in water was investigated in batch reactors at temperatures 110-200 degrees C. These acid catalyzed reactions are at high temperatures catalyzed by hydrogen ions formed by autodissociation of water. At temperatures 180-200 degrees C and reaction times 5-10 min more than 50 mol% yields of 4-HCP were achieved. A kinetic model which describes experimental data was developed. The values of the apparent activation energies of the main reaction and the side reactions are very similar, what means that the selectivity of 4-HCP formation is independent on the temperature. It indicates, that is attractive to perform furfuryl alcohol transformation to 4-HCP at high temperatures without changing the selectivity.
