Abstract
Taking 2-methoxy-5-nitrobenzoic acid as the material,the reduction reaction of nitro was studied.Through the research of several different methods of reduction reaction of hydrazine hydrate,Fe/HCl and Pd/C,the reaction temperature,reaction time,create of byproduct and aftertreatment were compared.The byproduct in the first two pathways were 57.2% and 41.5%,respectively,and the two methods were congruency industrial production.The byproduct in three pathway was 81.5%,and this method was congruency preparation procedure in lab.
