HCID 1414960912-Isocyanatododecanoic acid methyl ester

Procedure

0.1 mole 12-isocyanatododecanoic acid chloride was reacted as in Example 1 with 0.11 mole methoxytrimethyl silane at 75° C. until the acid chloride band at 1800 cm-1 had disappeared. The desired product was obtained after distillation.
