Chemische Eigenschaften
white or light yellow crystals or powder
Verwenden
Formanilide was used to study the zero electron kinetic energy(ZEKE) spectra of
cis- and
trans-formanilide. It was used to investigate the gas-phase structures of the two isomers of the
trans-formanilide-water complex by two-colour (1+1′) resonance enhanced multiphoton ionisation (REMPI) and ZEKE spectroscopy.
Definition
ChEBI: A member of the class of formamides that is formamide in which one of the amino hydrogens is replaced by a phenyl group.
Allgemeine Beschreibung
White crystalline solid.
Air & Water Reaktionen
FORMANILIDE may be sensitive to prolonged exposure to air. . Soluble in water.
Reaktivität anzeigen
FORMANILIDE 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).
Health Hazard
SYMPTOMS: Exposure to FORMANILIDE may cause cyanosis, headache, dizziness, confusion, decreased blood pressure, convulsions and coma.
Brandgefahr
FORMANILIDE is probably combustible.
läuterung methode
Crystallise formanilide from Et2O (m 45.3o), Et2O/pet ether (m 46o), pet ether (m 47.6o), ligroin/xylene, or distil it preferably under reduced pressure. [Beilstein 12 H 230, 12 II 135, 12 III 453.]
