Abstract

In this study, the conversion of bones (waste of food industry) into bone char is described. The presence of calcium phosphate and graphitic carbon gives bone char unique properties, with different possible uses. The catalytic behavior of bone char modified with chlorosulfonic acid is tested as reusable and eco-friendly solid acid biocatalyst in synthesis of pyrimidine-5-carbonitrile derivatives. The catalyst properties were characterized by different techniques such as FT-IR, BET, SEM, TEM, TGA, EDS and XRD. The bone char catalyst can be reused several times without reducing catalyst efficiency. In addition to the various reported benefits, the first use of bone char as a catalyst support for organic synthesis is an important novelty of this study.

摘要

本研究描述了将骨头（食品工业废料）转化为骨炭的过程。磷酸钙和石墨碳的存在赋予了骨炭独特的性能，使其具有多种可能的用途。测试了用氯磺酸改性的骨炭作为可重复使用且环保的固体酸生物催化剂在嘧啶-5-腈衍生物合成中的催化行为。通过傅里叶变换红外光谱（FT-IR）、比表面积分析仪（BET）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）、热重分析仪（TGA）、能谱仪（EDS）和X射线衍射仪（XRD）等不同技术对催化剂性能进行了表征。骨炭催化剂可以重复使用多次而不降低催化效率。除了已报道的各种益处外，骨炭首次用作有机合成的催化剂载体是本研究的一个重要创新点。
