| Abstract: | This paper recommends a new method for synthesizing 6-nitrobenzimidazole, using potassium nitrate and sulfuric acid instead of fuming nitric acid for nitrating benzimidazole, giving higher yield, and easy to manipulate during the product separation and purification. The product prepared with this method can perform normal anti-fogging effect during its use for preparing solutions aimed at processing medical and industrial radiographic films. |
