2-Ethyl-2-phenylmalonamide 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).
SYMPTOMS: Symptoms of exposure to a related compound through ingestion may include sedation, vertigo, dizziness, nausea, vomiting, ataxia, diplopia, nystagmus, an acute feeling of intoxication and, rarely, maculopapular and morbilliform rash, leukopenia, thrombocytopenia, systemic lupus erythematosus, lymphadenopathy, acute psychotic reactions, hemorrhagic disease in the neonate, megaloblastic anemia and osteomalacia.
