Flow chemistry technology has demonstrated significant potential in advancing the green transformation of the chemical industry while enhancing inherent process safety. Safety, cost-effectiveness, and operational efficiency serve as pivotal drivers for advancing flow chemistry in nitration processes. This review provides a comprehensive analysis of the continuous-flow nitration technology – a process historically recognized as one of the most hazardous industrial operations – focusing on its technological advancements in process design, reaction kinetics characterization, and practical implementation over the past decade. Detailed discussions encompass system configuration strategies, critical process parameters and operating ranges, performance evaluation metrics, universal methodologies for kinetics analysis, safety assessment protocols, and scale-up approaches. The presented content aims to offer actionable guidance for researchers and engineers engaged in the development of continuous-flow nitration systems.
While organolithium reactions hold great promise in synthetic chemistry, their high reactivity, strong exothermicity, and the instability of intermediates often limit their application, making the effective control of reaction processes difficult in traditional batch reactors. This review systematically summarizes the latest advances in utilizing flow chemistry technology to address process challenges related to organolithium reactions from 2014 to 2025. From a process perspective, we systematically discuss the literature cases regarding three key themes: the synthesis of organic compounds applied in the pharmaceutical field, the development of novel methods centered on effective process control (reaction temperature, residence time, phase state, multi-step reaction sequence, and safety), and fundamental process research on continuous flow organolithium reactions. Analysis shows that continuous flow systems provide a powerful platform for fully realizing the potential of organolithium chemistry by enhancing heat/mass transfer and precisely controlling reaction parameters. This review emphasizes how flow chemistry technology not only improves process safety and efficiency but also enables transformations and process scaling that are difficult or impossible in batch modes, thus providing a novel process intensification method for modern synthetic chemistry.
