采用二次法快速合成了Sn-β沸石。该方法包含杂原子脱除和与SnCl4的同晶取代两个步骤,合成时间从水热法的约40 d缩短为少于1 d,且Sn含量更高。将该沸石用于水相催化葡萄糖异构化制果糖反应,详细考察了反应温度、时间、催化剂用量、溶剂以及卤盐添加物对反应性能的影响。在优化的反应条件下,果糖收率最高可达约43%。催化剂可以通过焙烧再生。
Sn-βzeolites were facilely synthesized by a post-synthesis method consisting of two steps, i.e., het-eroatom removal and isomorphous substitution by reaction with SnCl4. This significantly shortened the Sn-βzeolite preparation time from the previously reported 40 d to less than 1 d. It was shown that Sn-βsamples prepared using the post-synthesis method had higher Sn contents than that pre-pared using a hydrothermal method. The as-synthesized Sn-βzeolites were tested in the isomeriza-tion of glucose to fructose in aqueous media. The effects of reaction temperature, reaction time, catalyst amount, solvent, and halide additive on the isomerization reaction over Sn-Al-β zeolites were studied in detail. Under the optimized conditions, the yield of fructose reached a maximum of~43%. The catalysts can be reused without loss of activity after regeneration by calcination.
