Benzamide Chemical Properties,Uses,Production

Description

Benzamide appears as off-white crystals or powder. It is combustible and incompatible with strong oxidising agents and strong bases. On combustion and thermal decomposition, it emits nitrogen oxides, carbon monoxide, and carbon dioxide.

Chemical Properties

off-white crystals or powder

Definition

ChEBI: An aromatic amide that consists of benzene bearing a single carboxamido substituent. The parent of the class of benzamides.

General Description

White powder.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Benzamide reacts with azo and diazo compounds to generate toxic gases. Forms flammable gases with strong reducing agents. Mixing with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. Combustion generates toxic mixed oxides of nitrogen (NOx).

Fire Hazard

Flash point data for Benzamide are not available, however Benzamide is probably combustible.

Purification Methods

Crystallise it from hot water (about 5mL/g), EtOH or 1,2-dichloroethane, and dry it in air. It has also been crystallised from dilute aqueous NH3, H2O, Me2CO, then *C6H6 using a Soxhlet extractor. Dry it in an oven at 110o for 8hours and store in a desiccator over 99% H2SO4. [Bates & Hobbs J Am Chem Soc 73 2151 1951, Beilstein 9 IV 725.]
