Continuous flow microchannel reactors are the "accelerator" for green upgrading in the pesticide industry. They offer technical advantages such as safety upgrade by handling dangerous intermediates safely, efficiency leap with reduced feed amount, shorter reaction time and higher yield, and being eco - friendly and energy - saving with less by - products, energy consumption and wastewater discharge. There are successful application cases from laboratory to industrialization, like Zheng's Chemical, Syngenta and a pesticide company. The YMC series devices of domestic benchmark enterprise have precise control, modular design and industrial - level performance. On the policy level, continuous flow technology is highly regarded, and the concept of ultra - limit manufacturing will drive pesticide production towards "chip - like" advancement with reduced energy consumption and increased efficiency.
