摘要： The present invention is to provide a production method of chemical reactive substances with stable quality by which solidification, gel formation, and the resulting blockade within material injection nozzles are prevented, and contamination of a reaction system with the gelled matter is prevented, as well as occurrence of problems on a production process due to the gelled matter is suppressed, when the chemical reactive substances are produced by injecting the liquid materials containing reactive substances having unsaturated double bonds into the reaction vessel through the material injection nozzles of the reaction vessel. The present invention is a production method of a chemical reactive substance which comprises injecting a liquid material containing a reactive substance having an unsaturated double bond into a reaction vessel through a material injection nozzle of said reaction vessel and causing a reaction at a reaction temperature of not less than 50° C, said production method of the chemical reactive substance including a step of removing at least a part of residual liquid remained in the material injection nozzle from inside of the material injection nozzle.
