Chloromethane is an important reagent for methylations in the process industry. However, as a gas suspected of causing cancer, it is rarely used at laboratory scale. Therefore, a setup is presented here for studies in a laboratory under safe and reproducible conditions. The use of a microreactor guarantees high heat transfer rates and a low holdup of the reagent. As a proof‐of‐concept, the reaction of chloromethane with the secondary amine morpholine in aqueous solution is investigated. By applying elevated pressures, a liquid‐liquid system with enhanced solubility of chloromethane in the aqueous phase is accessible.

实验室规模的微反应器工厂，用于研究液相氯甲烷的甲基化

氯甲烷是加工工业中甲基化的重要试剂。但是，作为怀疑会导致癌症的气体，它很少在实验室规模使用。因此，这里提出了一种在安全且可复制的条件下用于实验室研究的装置。使用微反应器可确保较高的传热速率和较低的试剂滞留率。作为概念验证，研究了氯甲烷与仲胺吗啉在水溶液中的反应。通过施加高压，可以得到具有增强的氯甲烷在水相中溶解度的液-液体系。
