Description

technical field [0001] The invention belongs to the technical field of organic synthesis, and in particular relates to a flow chemical reaction device. Background technique [0002] Organic synthesis refers to the process of synthesizing organic matter from simpler compounds or simple substances through chemical reactions. Sometimes degradation of complex raw materials to simpler compounds is also included. Organic synthesis often uses reaction conditions such as heating, light, microwave and even pressure. [0003] A core content of organic synthetic chemistry is the synthesis of various organic molecules. In scientific research and development based on universities and scientific research institutes, the synthesis of natural products, drugs, and functional molecules requires a large number of organic reactions, while the traditional synthesis method uses a glass flask as a reactor synthesis method, known as For batch chemistry. The reagents required for the reaction ar...
