9361728 Genders This is a Phase I award under the Small Business Innovation Research Solicitation. In a previous effort, a process based on the electrochemical hydrodimerization of formaldehyde at a graphite cathode was developed. A drop in oil prices, and a resultant drop in ethylene prices, the feedstock for the major present process for ethylene glycol, made the new process economically unattractive. This effort is an extension of the earlier work designed to reduce the capital and operating costs required. Modifications include operating in an undivided, narrow-gap cell with noncatalytic electrodes thus eliminating the need for costly membranes and catalysts; using solvent extraction for product isolation and employing gas-diffusion electrodes. Ethylene glycol is an important commodity chemical. It is a precurser to polyester, is the principal antifreeze compound in use, and has other applications in chemical processing.

9361728性别这是小型企业创新研究征集活动的第一阶段奖项。在以前的工作中，开发了一种基于甲醛在石墨阴极上的电化学加氢二聚的工艺。石油价格下跌，以及由此导致的乙烯价格下跌，使新工艺在经济上失去了吸引力。这一努力是早期工作的延伸，旨在减少所需的资本和运营成本。改进包括在带有非催化电极的完整的窄间隙电池中操作，从而消除了对昂贵的膜和催化剂的需要；使用溶剂萃取进行产品分离，并使用气体扩散电极。乙二醇是一种重要的商品化学品。它是聚酯的前驱，是使用中的主要防冻剂，并在化学加工中有其他应用。
