Abstract The oxidation of ethanol to acetaldehyde was previously investigated in a continuous flow bench scale reactor using a zirconium-oxide-supported vanadium catalyst. Products were analyzed by near-infrared spectroscopy, a fast and accurate tool for the determination of water, ethanol, and acetaldehyde content. Water content was calibrated by Karl Fischer titration while gas chromatography was used to calibrate ethanol and acetaldehyde contents. Near-infrared spectroscopy is a fast, cost-effective method for the determination of water, ethanol, and acetaldehyde products from partial ethanol oxidation.

近红外光谱作为乙醇部分氧化中水分含量分析的快速工具

摘要 先前使用氧化锆负载的钒催化剂在连续流动的台式反应器中研究了乙醇氧化成乙醛。产品通过近红外光谱分析,这是一种快速、准确测定水、乙醇和乙醛含量的工具。水含量通过卡尔费休滴定法校准,而气相色谱法用于校准乙醇和乙醛含量。近红外光谱是一种快速、经济的方法,用于测定部分乙醇氧化产生的水、乙醇和乙醛产物。
