Phenyl Isocyanate - an overview ScienceDirect Topics

Phenyl isocyanate is an organic compound typically abbreviated PhNCO. The molecule consists of a phenyl ring attached to the isocyanate functional group. It is a colourless liquid that reacts with water. Phenyl isocyanate has a strong odor and tearing vapours, therefore it has to be handled with care. Characteristic of other isocyanates, it reacts with amines to give ureas. Similarly… WebThe formula for aniline compounds is C 6 H 5 NH 2, where the amino group is meant to be connected to the phenyl ring. Aniline is a primary aromatic amine. By heating aniline with chloroform in the presence of KOH, aniline can be transformed into phenyl isocyanide. Ph - NH 2 ( s) + CHCl 3 ( aq) + 3 KOH ( aq) → Ph - NC ( s) + 3 KCl ( aq) + 3 H ...
