Preparation of Octadecyl isocyanate: Octadecylamine reacts with phosgene in chlorobenzene to get octadecylamine chloride, and then we can get the product by thermal decomposition and vacuum distillation. The following are the reaction equations:
CH₃(CH₂)₁₇NH₂+COCl₂→CH₃(CH₂)₁₇NHCOCl+HCl
CH₃(CH₂)₁₇NHCOCl→CH₃(CH₂)₁₇NCO+HCl

Uses of Octadecyl isocyanate: It is used as synthetic raw material of printing and dyeing assistant and wool textile softener VS. It also can react with 1(2)H-tetrazol-5-ylamine to get 5-amino-tetrazole-1-carboxylic acid octadecylamide. This reaction needs solvent pyridine at ambient temperature. The reaction time is 3 hours. The yield is 38%.
