Abstract—The kinetics of the noncatalytic reactions of isophorone diisocyanate with n-propanol, isopropanol,
1,3-diazidopropan-2-ol, propargyl alcohol, and phenol in toluene in the temperature range from 20 to 90C at
the stoichiometric ratio of reactive groups has been investigated by IR spectroscopy. The apparent rate constants
for the reactions of the aliphatic and cycloaliphatic isocyanate groups of isophorone diisocyanate with all of the
alcohols have been measured. The activation parameters of the reactions of isophorone diisocyanate with n-pro-
panol, isopropanol, and 1,3-diazidopropan-2-ol have been determined. The data obtained are considered in
terms of the alcohol structure and molecular organization of solutions.

Keywords: isophorone diisocyanate, urethane formation, kinetics, n-propanol, isopropanol, 1,3-diazidopropan-
2-ol, propargyl alcohol, phenol
