Paragraph 0071, (2016/10/10)
The invention relates to a synthesis method of o-nitrophenol compounds, solving the problems that production hazards are easily caused due to the release of a large deal of heat during the synthesis of o-nitrophenol and the severe environment pollution caused due to the generation of a large deal of waste gas and acid in the process in the prior art. The invention provides the synthesis method of the o-nitrophenol compounds, which comprises the steps: synthesizing 2-(phenoxy)pyridine from phenol compounds; and then sequentially adding 2-(phenoxy)pyridine and a catalyst, a nitrating reagent, an oxidant and an organic solvent into a sealed pressure container, heating and reacting for 10-50 hours in an oil bath of which the temperature is 80 DEG C-130 DEG C to obtain 2-(2-nitrophenyl)oxy pyridine; and finally treating to obtain o-nitrophenol. The synthesis method is simple, convenient and efficient.
