研究了在纯水溶液和两相有机物/水混合物中木糖自催化脱水制糠醛的反应，以确定反应介质和条件对转化率和产率的影响。该研究确定了由汉森溶解度参数δP确定的反应的严重性（Ro）和极性与木糖转化率和糠醛产率强烈相关。在环丁砜、γ-丁内酯、γ-戊内酯、γ-己内酯和四氢呋喃的纯水溶液和有机/水混合物中，增加Ro和δP增加了转化率和产率。另外，发现在指定的Ro和δP下，使用时间、温度和溶剂混合物的不同组合实现了类似的转化率和产率。使用主成分分析和对潜在结构的投影，开发了半经验模型，该模型提供了在实验Ro和δP值范围内的木糖转化率和糠醛产率的估计。
Autocatalytic dehydration of xylose to furfural was studied in pure aqueous and monophasic organic/water mixtures to determine the effect reaction media and conditions have on conversion and yield. This study identified that the severity (Ro) of the reaction and polarity, as determined by the Hansen Solubility Parameter, δP, strongly correlate with xylose conversion and furfural yield. Increasing the Ro and δP increased both conversion and yield in pure aqueous and organic/water mixtures of sulfolane, γ‐butyrolactone, γ‐valerolactone, γ‐hexalactone, and tetrahydrofuran. Additionally, it was found that at a specified Ro and δP, similar conversions and yields were achieved using different combinations of time, temperature, and solvent mixture. Using principal component analysis and projection to latent structures, a semi‐empirical model was developed that provided estimates of xylose conversion and furfural yield over a range of experimental Ro and δP values.
