Cosa (chi) è huile essentielle - definizione


Aniline         
  • 2,6-diisopropylaniline]], a colorless liquid when pure, illustrating the tendency of anilines to air-oxidize to dark-colored products.
  • The lone electron pair on the nitrogen delocalizes into the pi system of the benzene ring. This is responsible for nitrogen’s weaker basicity compared to other amines.
  • [[Ball-and-stick model]] of aniline from the [[crystal structure]] at 252 K
  • 400px
  • Aniline can react with bromine even in room temperatures in water. Acetyl chloride is added to prevent tribromination.
  • Cake of [[indigo dye]], which is prepared from aniline.
  • [[Polyaniline]]s can form upon oxidation of aniline.
  • Most aniline is consumed in the production of [[methylenedianiline]], a precursor to polyurethanes.

·adj Made from, or of the nature of, aniline.
II. Aniline ·noun An organic base belonging to the phenylamines. It may be regarded as ammonia in which one hydrogen atom has been replaced by the radical phenyl. It is a colorless, oily liquid, originally obtained from indigo by distillation, but now largely manufactured from coal tar or nitrobenzene as a base from which many brilliant dyes are made.
