What is Octadecyl isocyanate?

The Uses of Octadecyl isocyanate

Octadecyl 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.

The Uses of Octadecyl isocyanate

Octadecyl 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.

The Uses of Octadecyl isocyanate

Octadecyl 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)

What are the applications of Application

Octadecyl isocyanate is a biochemical used to modify the surface of cellulose nanocrystals

Safety Profile

Poison by intravenous route. A flammable liquid. When heated to decomposition it emits toxic fumes of NOx. See also ISOCYANATES.
