Abstract

Eggshell waste has proved to be one of the most valuable natural sources due to its considerable contributions to several research fields. Herein, calcium oxide derived from various kinds of eggshell wastes has been introduced using the calcination method at different temperatures. The prepared micro- or nano-particles of calcium oxide are also characterized by XRD, FE-SEM, TEM, BET, and FT-IR techniques to clarify their morphological and structural aspects completely. With mild basicity, this bio-derived catalyst has been applied to the green synthesis of chalcones via the Claisen − Schmidt condensation reaction. Ultimately, the reusability of the catalyst is examined to increase the catalyst economization.
蛋壳废弃物转化为固体碱催化剂促进无溶剂Claisen−Schmidt缩合反应的研究
蛋壳废弃物已被证明是最有价值的天然资源之一,因为它在几个研究领域做出了相当大的贡献。本文介绍了在不同温度下煅烧各种蛋壳废弃物制备氧化钙的方法。利用XRD、FE-SEM、TEM、BET、FT-IR等技术对所制备的微纳米氧化钙颗粒进行了表征,全面阐明了其形态和结构特征。该生物衍生催化剂具有温和的碱性,通过Claisen - Schmidt缩合反应用于绿色合成查尔酮。最后,考察了催化剂的可重复使用性,以提高催化剂的经济性。
