Description

Description générale

Phenyl isocyanate is an aromatic monoisocyanate which is a constituent of diphenyl methane diisocyanate. It is suitable to make aryl ureas with amine at room temperature making it unlikely to detect isocyanate formation using NMR. It reacts with amino acids in alkaline solution and with peptone.

Application

Phenyl isocyanate was used in preparing grapheme-polymer nanocomposites by mixing exfoliated phenyl isocyanate-treated graphite oxide sheets with polystyrene. It was used in studying its reaction of o-hydroxybenzyl alcohol in polar solvents with in situ FT-IR which showed that phenolic hydroxyl group reacts easily than aliphatic hydroxyl group.
