Flow synthesis, is attracting attention not only in the field of basic chemicals but also in various industries as a continuous production process that replaces batch production. In the pharmaceutical field as well, the FDA (US Food and Drug Administration) recommends continuous production, and research and development of continuous flow processes is accelerating rapidly. In this session, we will introduce the current status and future prospects of flow synthesis and micro-reactors, as well as examples of development and practical application at related chemical companies and equipment companies, and examples of deployment to the pharmaceutical industry.
