2,5-Difluorophenylhydrazine hydrochloride Chemical Properties,Usage,Production
Uses
2,5-Difluorophenylhydrazine, HCl
Synthesis
Using 2,5-difluoroaniline as raw material, in 3 times the amount of concentrated hydrochloric acid, glacial acetic acid as a co-solvent, and adding 3% of the mass of raw material PEG-400 as a phase-transfer catalyst, the diazotization reaction was carried out at -5 0 for 1 h with 1.05 times the amount of molar sodium nitrite (prepared as an aqueous solution). 1.05 times the molar amount of sodium nitrite (prepared as an aqueous solution) -5 ~ 0 under the condition of diazotization reaction for 1 h; sodium bisulfite as a reducing agent, diazotization solution 75 reduction reaction 1h, the resulting reduction products were used as the phase transfer catalyst, and the phase transfer catalyst was used as the phase transfer catalyst. 1h, the obtained reduction product was acid precipitated by concentrated hydrochloric acid at 85 for 2 h, . 2,5-difluorophenylhydrazine hydrochloride was prepared; finally, 2,5-difluorophenylhydrazine hydrochloride could be obtained by alkaline hydrolysis of 2,5-difluorophenylhydrazine hydrochloride with sodium hydroxide, the content 96% (HPLC), the yield was 74% (with 2,5-difluorophenylhydrazine hydrochloride). 74% (as 2,5-difluorophenylhydrazine).
