The Study of Novel Synthetic Method of 2-Cyanobenzoic Acid

A novel synthetic method of 2-cyanobenzoic acid was introduced.Ideal product can be got through ammonolysis,dehydration and acidification when the phthalic anhydride was used as raw material.The total yield was achieved to 75%.Comparing to other ordinary methods,this synthetic route had many advantages,such as cheap raw materials,mild reaction conditions,simple operation,and higher yield,especially,high toxic cyanide salt was not used.So it had broad application prospects in industry production.
