Abstract

In this study, hydrogen production through the hydrolysis, ethanolysis, and methanolysis reactions of NaBH₄ using adipic acid as a catalyst was investigated for the first time. Adipic acid solutions were prepared with methanol and ethanol at concentrations of 0.1, 0.2, 0.3, 0.4, and 0.5 M. In these reactions, NaBH₄-MR (methanolysis) and NaBH₄-ER (ethanolysis) reactions were carried out at 30, 40, and 50 °C with NaBH₄ concentrations of 1.25%, 2.5%, and 5%. Hydrolysis reactions (NaBH₄-HR) were conducted at 0.1 M under the same conditions. In the ethanolysis and methanolysis reactions at 30 °C, total hydrogen conversion was achieved at 0.3 M, 0.4 M, and 0.5 M. However, in the hydrolysis reactions, total hydrogen production was only obtained at 50 °C. It was observed that in the NaBH₄-MR and NaBH₄-ER reactions, total hydrogen conversion could be achieved within 4-5 s. The utilization of adipic acid as a catalyst for hydrogen production from NaBH₄ through ethanolysis and methanolysis reactions is proposed as a highly efficient and fast method, characterized by impressive conversion rates.

硼氢化钠高效快速制氢：己二酸在水解、甲醇分解和乙醇分解反应中的作用。

本研究首次研究了以己二酸为催化剂通过 NaBH4 的水解、乙醇分解和甲醇分解反应制氢的过程。在这些反应中，NaBH4-MR（甲醇分解）和 NaBH4-ER（乙醇分解）反应分别在 30、40 和 50 °C、NaBH4 浓度为 1.25%、2.5% 和 5%的条件下进行。水解反应（NaBH4-HR）在相同条件下以 0.1 M 的浓度进行。在 30 °C的乙醇分解和甲醇分解反应中，0.3 M、0.4 M 和 0.5 M 的氢转化率均达到了 100% 。研究发现，在 NaBH4-MR 和 NaBH4-ER 反应中，可在 4-5 秒内实现氢气的完全转化。利用己二酸作为催化剂，通过乙醇分解和甲醇分解反应从 NaBH4 中制氢是一种高效、快速的方法，其特点是转化率高。

期刊介绍： Molecules (ISSN 1420-3049, CODEN: MOLEFW) is an open access journal of synthetic organic chemistry and natural product chemistry. All articles are peer-reviewed and published continously upon acceptance. Molecules is published by MDPI, Basel, Switzerland. Our aim is to encourage chemists to publish as much as possible their experimental detail, particularly synthetic procedures and characterization information. There is no restriction on the length of the experimental section. In addition, availability of compound samples is published and considered as important information. Authors are encouraged to register or deposit their chemical samples through the non-profit international organization Molecular Diversity Preservation International (MDPI). Molecules has been launched in 1996 to preserve and exploit molecular diversity of both, chemical information and chemical substances.
