摘要

氧化锌基材料具有更强的热稳定性和化学稳定性，是去除产生异味的污染物和化合物的理想选择。蓖麻油酸的锌盐（俗称蓖麻油酸锌）被认为是性能最佳的材料。本文介绍了一种创新的两步法合成蓖麻油酸锌盐的方法，第一步是制备中间化合物蓖麻油酸甲酯，该化合物是通过蓖麻油与甲醇的酯交换反应并在氢氧化钠催化下合成的。第二步是通过蓖麻油酸甲酯在氧化锌颗粒存在下的皂化反应制备蓖麻油酸锌。XRD、FTIR 和 NMR 光谱证实了蓖麻油酸甲酯和蓖麻油酸锌的合成。HR-SEM 和 AFM 图像显示形成了较大的颗粒，而 TGA 则证实了材料的热稳定性。

Novel Preparation and Characterization of Zinc Ricinoleate Through Alkali Catalysis.

The enhanced thermal and chemical stability of Zinc oxide-based materials make them excellent candidates for the removal of odor-producing pollutants and compounds. The zinc salt of ricinoleic acid, commonly known as zinc ricinoleate, is viewed as the top performer. This article describes an innovative two-step synthesis of zinc ricinoleate, where the first step consists of the preparation of an intermediate compound, methyl ricinoleate, which is synthesized via transesterification of castor oil with methanol and catalyzed by sodium hydroxide. The second step comprises the preparation of zinc ricinoleate through the saponification of methyl ricinoleate in the presence of zinc oxide particles. XRD, FTIR, and NMR spectroscopies confirmed the synthesis of methyl ricinoleate and zinc ricinoleate. HR-SEM and AFM images showed the formation of larger particles, while the thermal stability of the materials was confirmed by TGA.

期刊介绍： Polymers (ISSN 2073-4360) is an international, open access journal of polymer science. It publishes research papers, short communications and review papers. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Polymers provides an interdisciplinary forum for publishing papers which advance the fields of (i) polymerization methods, (ii) theory, simulation, and modeling, (iii) understanding of new physical phenomena, (iv) advances in characterization techniques, and (v) harnessing of self-assembly and biological strategies for producing complex multifunctional structures.
