What is 3'-Methylacetanilide?

Chemical properties

white crystalline solid

General Description

White solid.

Air & Water Reactions

Water insoluble.

Reactivity Profile

3'-Methylacetanilide is an amide. Flammable gases are formed by the reaction of organic amides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).

Health Hazard

ACUTE/CHRONIC HAZARDS: When heated to decomposition 3'-Methylacetanilide emits toxic fumes of nitrogen oxides.

Fire Hazard

Flash point data for 3'-Methylacetanilide are not available; however, 3'-Methylacetanilide is probably combustible.

Safety Profile

Moderately toxic by ingestion. Seealso p-ACETOTOLUIDIDE. When heated todecomposition it emits toxic fumes of NOx.

Purification Methods

Crystallise the toluidide from H2O, EtOH, aqueous EtOH or Et2O/pet ether (m 66o). UV: max 245nm (EtOH). [Beilstein 12 H 860, 12 I 400, 12 II 468, 12 III 1962, 12 IV 1823.]
