| Questions And Answer | Back Directory | [Preparation]
N-phenylmaleimide can be prepared by reacting maleic anhydride with aniline. The reaction involves the formation of an amide acid in the first stage and iminolation in the second stage. Previously, iminolation was prone to side reactions that reduced yield and purity. Now, a catalytic method is used, avoiding side reactions and improving both yield and purity. |

Yellow needles. | [Reactivity Profile]
N-PHENYLMALEIMIDE(941-69-5) 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). | [Air & Water Reactions]
