What is N-Phenylmaleimide?

Chemical properties

yellow crystalline powder or needles

The Uses of N-Phenylmaleimide

N-phenylmaleimide can be used as cross-linking agent in rubber vulcanization, can improve the heat resistance, impact resistance, hot melt processability. Also be used to produce heat-resistant polymers.

The Uses of N-Phenylmaleimide

Dienophile in the Diels-Alder reaction. Usually gives cryst adducts.

The Uses of N-Phenylmaleimide

N-Phenylmaleimide is used as a dipolarophile in 1,3-cycloaddition reaction with a nitrone, useful for the preparation of crystalline adducts of dienes. It is used as a plastic modifier.

General Description

Yellow needles.

Air & Water Reactions

Sparingly water soluble .

Reactivity Profile

N-Phenylmaleimide is an imide. 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).

Fire Hazard

Flash point data for N-Phenylmaleimide are not available. N-Phenylmaleimide is probably combustible.
