直到最近，有机化学中的传统加热一直是用油加热浴或使用电热交换器来完成的。随着微波设备的出现，微波加热被迅速引入有机化学实验室作为标准方法，主要是因为在高温下操作的方便性，伴随着加速的反应速率。在本论文中，我们讨论了通过使电流直接通过反应器壁来加热小型连续操作反应器的方法，作为有机化学中的一种使能技术。这种方法的好处是热量直接在反应器壁内产生。通过这种方式，可以达到与微波炉相当的高加热速率，但设备成本低得多。为微波加热和传统加热的比较提供了一个工具。作为一个例子，甲酸甲酯的酸催化水解的动力学数据测量使用这种加热概念。该反应不仅是一个合适的模型，而且是一个工业上的重要性，因为这是甲酸的主要生产过程。
Until recently traditional heating in organic chemistry has been done with oil heating baths or using electric heat exchangers. With the advent of microwave equipment, heating by microwaves was rapidly introduced as standard method in organic chemistry laboratories, mainly because of the convenient possibility to operate at high temperature accompanied by accelerated reaction rates. In the present contribution we discuss the method of heating small, continuously operated reactors by passing electric current directly through the reactor wall as an enabling technology in organic chemistry. The benefit of this method is that the heat is generated directly inside the reactor wall. By this means high heating rates comparable to microwave ovens can be reached but at much lower cost for the equipment. A tool for the comparison of microwave heating and traditional heating is provided. As an example kinetic data for the acid catalyzed hydrolysis of methyl formate were measured using this heating concept. The reaction is not only a suitable model but also one of industrial importance since this is the main production process for formic acid.
