在水相介质中，以锡-β沸石为催化剂，研究了木糖异构化的非酶反应路线。木果糖和莱克糖是主要和次要产品。木糖的最高产率为27%，在100℃时木糖的转化率类似于60%，产率为11%。当SnBeta沸石与Bronsted酸催化剂结合时，木糖在水介质中一锅内生成糠醛的温度比通常用于该反应的温度低得多。
A nonenzymatic route for xylose isomerization in an aqueous medium using zeolite Sn-beta as a catalyst is demonstrated. Xylulose and lyxose are the primary and secondary products. the maximum yield to xylulose is 27%, with an 11% yield to lyxose at similar to 60% xylose conversion at 100 degrees C. When the Sn-beta zeolite is combined with a Bronsted acid catalyst, furfural forms in a single pot from xylose in an aqueos medium at much lower temperature than typically employed for this reaction.
