Abstract
ConclusionsIn the carbonylation of 2,4-dinitrotoluene using CO the extremal character of the yield of 1-methylbenzene 2,4-diisocyanate as a function of the temperature and pyridine concentration is apparently caused mainly by the coupling of two factors: an increase in the synthesis rate of the isocyanate with increase in either the reaction temperature or the pyridine concentration in solution and the instability of the isocyanate under the conditions of its synthesis.
