Octadecyl isocyanate Usage And Synthesis
UsesOctadecyl Isocyanate is a useful reagent for the surface modification of poly(Me methacrylate) (PMMA) to form PMMA surfaces terminated with well-ordered and highly crystalline octadecane chains.
UsesOctadecyl isocyanate (n-octadecyl isocyanate) was employed for chemical modification of:
  • surface of cellulose nanocrystals to promote interfacial filler/matrix interactions
  • poly (2-hydroxyethyl methacrylate) (pHEMA) films, to investigate in vitro hemocompatibility assay using freshly drawn human whole blood
  • cellulose nanocrystals (or whiskers) and microfibrillated cellulose (MFC)
UsesOctadecyl isocyanate can be used as a modifier:
  • For cellulose nanocrystals in the synthesis of poly(butylene adipate-co-terephthalate) (PBAT) based nanocomposites with improved mechanical and rheological properties.
  • For lignin to effectively incorporate the lignin fillers in polyurethane matrix to prepare composites.

It can be reacted with various amines to synthesize variety of unsymmetrical urea derivatives.
Safety ProfilePoison by intravenous route. A flammable liquid. When heated to decomposition it emits toxic fumes of NOx. See also ISOCYANATES.
