Abstract
PURPOSE: To obtain the titled compound of high quality, having improved weather resistance, etc., and useful for a coating material, etc. with a slight formation of byproducts or chlorinated derivatives, by phosgenating ethyl 2,6,2'-triaminohexanoate trihydrochloride at a specific reaction temperature.
CONSTITUTION: Ethy 2,6,2'-triaminohexanoate trihydrochloride is phosgenated to give ethyl 2,6,2'-triisocyanatohexanoate. In the process, the phosgenation reaction temperature is set in the range of 100W150°C, preferably 110W140°C, most preferably 120W130°C. The reaction in the temperature range provides the suppressed formation of chlorinated derivatives as by-products. The titled compound has many advantages as folows: Contribution to the reduction in the irritant action of the isocyanates on the skin mucous membranes, low viscosity, high NCO content or high curing rate.
