What is PHTHALAMIDE?

Chemical properties

colourless crystals or white crystalline powder

Definition

ChEBI: Phthalamide is a benzenedicarboxamide. It is functionally related to a phthalic acid.

General Description

Colorless crystals or off-white powder.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

PHTHALAMIDE is an amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides 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). PHTHALAMIDE is incompatible with acids. .

Health Hazard

ACUTE/CHRONIC HAZARDS: When heated to decomposition PHTHALAMIDE emits toxic fumes of nitrogen oxides.

Fire Hazard

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

Safety Profile

Low toxicity by intravenous route.When heated to decomposition it emits toxic vapors ofNOx and I^-.
