Abstract

Producer and production of aromatic fluorine compound are disclosed. The outlet port on bottom of diazotizing reactive kettle is connected with material transferring pump, outlet of transferring pump is connected to thermal decomposing piping reactor and outlet of piping reactor is communicated with receiver. The production consists of diazotization reaction, thermal decomposition process and separation process. The thermal decomposition process is carried out by transferring material in diazotizing reactive kettle to thermal decomposing reactor and controllable thermal decomposing. It has less consumption and higher production efficiency.

Description

technical field [0001] The invention relates to a production device and a production method suitable for aromatic fluorine compounds, especially a production device and a production method suitable for aromatic fluorine compounds whose intermediate product is a liquid diazonium compound. Background technique [0002] Fluorine-containing compounds, especially aromatic fluorine compounds, are widely used, involving fluorine-containing intermediates, fluorine-containing medicines, fluorine-containing pesticides, fluorine-containing surfactants and various fluorine-containing treatment agents. Taking fluorobenzene as an example, it is one of the basic products of organic fluorine fine chemicals, and it is the main raw material for the preparation of specific antipsychotic drugs such as trihaloperidol, trifluperidine, penfluridol, etc. The intermediate of quinone drug ciprofloxacin. At present, the international and domestic markets are generally tight, and the export situation ...
