Abstract

As microwave-assisted reactions become more common in the laboratory, numerous incidents involving fires and explosions have been reported, especially when domestic microwave ovens are used to heat flammable liquids. An evaluation of this emerging technology is necessary to assess the adequacy of the control measures that are currently in place to protect the laboratory worker from exposure to hazardous materials and unsafe work practices. In this report, the unique chemistry associated with microwave heating effects are summarized, the advantages of laboratory microwave ovens over domestic models are categorized, the applicable “Green Chemistry” attributes are discussed, and the risks associated with heating a flammable liquid in a domestic microwave oven are examined. Chemical reactions that involve heating flammable liquids in domestic microwave ovens present unacceptable risks. Scientists seeking to advance the state-of-the-art in chemistry by exploiting the unusual effects that microwave-assisted reactions offer should do so using laboratory-grade microwave ovens that possess requisite safety features. Documentation and publication of unanticipated events that result from relatively common occurrences will decrease risk associated with microwave-assisted reactions with flammable liquids.

使用装有易燃液体的微波炉
随着微波辅助反应在实验室中变得越来越普遍,已经报道了许多涉及火灾和爆炸的事件,特别是当家用微波炉用于加热易燃液体时。有必要对这一新兴技术进行评价,以评估目前为保护实验室工作人员免受危险材料和不安全工作做法的影响而采取的控制措施是否充分。在本报告中,总结了与微波加热效应相关的独特化学,分类了实验室微波炉相对于家用型号的优势,讨论了适用的“绿色化学”属性,并检查了在家用微波炉中加热可燃液体的风险。在家用微波炉中加热易燃液体的化学反应存在不可接受的风险。科学家们想要利用微波辅助反应带来的不同寻常的效应来推动化学领域的最新发展,就应该使用具有必要安全特性的实验室级微波炉。由相对常见的事件导致的意外事件的记录和出版将减少与可燃液体微波辅助反应相关的风险。
