Amines degradation

Base-catalysed quaternary ammonium salts give alkenes and 3° amines. This reaction is known as Hofmann elimination or Hofmann degradation. Amines can readily be converted to quaternary ammonium salt by the treatment of excess primary alkyl halides, and then Ag20 and H2O. Quaternary ammonium salts undergo E2 elimination, when heated with NaOH to give alkenes and tertiary amines. Thermal decomposition of a quaternary ammonium salt by NaOH to an alkene is known as Hofmann elimination. 

The castings of the molecular network system are transparent to translucent. As the rubber content increased, a brownish hue became apparent. This change often indicates the presence of a degraded amine. The transparency is...
