Preparation of Benzamide: It is obtained by the reaction of benzoyl chloride and ammonia. First, adding ammonium carbonate and the ammonia which the relative density is below 0.905 into glass-lined reacter, and stirring, adding Benzoyl chloride dropwise below 40 °C. After finished, keep stirring 30min until there is no Benzoyl chlorine smell. The crude product is filtered, washed and distilled with water to get recrystallization.
Uses of Benzamide: It is used in the determination of glycine. And it is also used as intermediates in organic synthesis. In addition, this chemical is used in the production of pharmaceuticals and dyes.
When you are using this chemical, please be cautious about it as the following:
It is harmful if swallowed, so people should not breathe dust and avoid contact with skin and eyes. It is hazardous, so the first aid measures and others should be known. When on the skin: first, should flush skin with plenty of water immediately for at least 15 minutes while removing contaminated clothing. Secondly, get shoesmedical aid . Or in the eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Then get medical aid soon. While, it's inhaled: Remove from exposure and move to fresh air immediately. Give artificial respiration while not breathing. When breathing is difficult, give oxygen. And as soon as to get medical aid.
