Synthesis of 3-formyltetrahydrothiopyran(中间体3-甲酰四氢噻喃的合成)
Zhejiang Daxue xuebao. Lixue ban, 2007 3-甲酰四氩噻喃是噻草酮的重要中间体，3-甲酰四氢噻喃的合成采用以丙烯醛和硫化氢为原料首先得到3-甲酰-5，6-二氢噻喃，然后3-甲酰-5，6-二氢噻喃在催化剂作用下氢化得到目标产物的合成路线.合成3-甲酰-5，6-二氢噻喃中，对内烯醛投料方式、硫化氢投入量和催化剂选择进行了优化试验，提出了新的反应机理，使3-甲酰-5，6-二氢噻喃反应收率和质量分数分别达到93%和95%以上.制备3-甲酰四氢噻喃中，对催化剂进行了选择试验，发现用Raney-Ni作催化剂，目标产物的质量分数和收率达到92%和94%以上.

Preliminary exploration of heavy metal accumulation in Agaricus bisporus [PDF]
, 2016 随着工业化和城镇化的快速发展，越来越多的重金属污染物通过各种途径被释放到土壤等环境中。其不仅直接毒害土壤生物和植物，破坏生态结构，还可以通过食物链迁移转化，危害人体健康。究竟如何修复重金属污染是当前重要的环境问题。 本课题以人工培养的双孢蘑菇（Agaricusbisporus）AS2796为主要研究对象。对其以及杏鲍菇、茶树菇和秀珍菇菌丝体做不同浓度的重金属Pb、Cd和As胁迫处理，研究四种大型真菌重金属富集能力。检测结果表明双孢蘑菇较其他3个菌株而言，对Pb和Cd的富集能力更强。在1mg/L条件下 ...
