Process for producing toluylene diisocyanate, specific mixture of toluylene diamine and water, and use of the mixture for producing toluylene diisocyanate |
| abstract |
(57) Abstract: A method for producing toluylene diisocyanate is provided. SOLUTION: 1) Step of reacting toluene with nitric acid to produce dinitrotoluene; 2) Hydrogenation of the dinitrotoluene to produce a crude solution of toluylenediamine and reaction water; 3) Reaction with toluylenediamine. Distilling the crude solution of water to produce an intermediate mixture of toluylenediamine and water [wherein the distillation is interrupted at a water content of the intermediate mixture of about 1-40% by weight], 4) transporting said intermediate mixture of toluylenediamine and water from the first manufacturing plant to the second manufacturing plant, Subsequently, 5) completely distilling said intermediate mixture of toluylenediamine and water in a second production plant to produce dry toluylenediamine, and 6) phosgenating said dry toluylenediamine to toluylenediamine. A process for producing toluylene diisocyanate comprising the step of producing an isocyanate. |
