The focus of this research is developing conditions which will make dimethyl carbonate an industrially viable alkylating agent for the preparation of quaternary ammonium salts. In a second part of the project, the products of the alkylation reactions will be transformed into a series of salts with varying counter ions. Thirdly, several biodegradable quaternary salts will be constructed as possible alternatives to the environmentally less friendly salts now used in commercial products. The project will serve as platform for the education of undergraduate chemistry students. With this Technology for a Sustained Environment award, the Synthetic Organic Program, as part of the NSF/EPA Partnership, is supporting the research and educational activities of Dr. Gary W. Earl of the Department of Chemistry at Augustana College. Professor Earl will focus his work on developing new and viable methods for the production of quaternary ammonium compounds. These compounds find wide industrial use as components of products as diverse as fabric softeners to hair conditioning agents. Undergraduate chemistry majors will be exposed to the constraints of industrial processing, both equipment and reaction conditions, as well as economic limitations.

这项研究的重点是发展条件， 碳酸二甲酯是一种工业上可行的烷基化剂， 季铵盐的制备。 的第二部分中 项目，烷基化反应的产物将被转化为 转化成一系列具有不同抗衡离子的盐。第三，若干 将尽可能地构建可生物降解的季盐 替代目前使用的对环境不太友好的盐， 商业产品。 该项目将作为平台， 化学本科生的教育。通过这项技术， 一个可持续环境奖，合成有机计划，作为一部分， NSF/EPA合作伙伴关系正在支持研究和教育 加里W.化学系的伯爵， 奥古斯塔纳学院。 厄尔教授将把工作重点放在开发新的 以及生产季铵化合物的可行方法。 这些化合物作为产品的组分具有广泛的工业用途， 从织物柔软剂到头发调理剂。 本科 化学专业的学生将受到工业的限制， 工艺，设备和反应条件，以及经济 局限性。
