| titleOfInvention | PROCEDURE TO PREPARE TOLUILENDIISOCIANATE. |
| abstract | TOLUILENE DIISOCIANATE IS OBTAINED BY NITRIFICATION OF TOLUOL TO GIVE DINITROTOLUOL, HYDROGENATION OF DINITROTOLUOL, OPTIONALLY IN THE PRESENCE OF A SOLVENT OR DILUENTLY, TO GIVE A GROSS DISSOLUTION OF TOLUOLENE DIUMULATION OF TOLUOLENE DIOLATION OF TOLUOLENE OBTAIN THE DRY TOLUYLENE DIAMINE OF COMMERCIAL QUALITY AND PHOSGENIZATION OF THE TOLUYLENE DIAMINE TO GIVE THE TOLUYLENE DIISOCIANATE, INTERRUPTING THE DISTILLATION TREATMENT OF THE TOLUYLENE DIOLINE SOLUTION FOR THE OPENING OF THE TOLUYLENE DIUMINATION OF A TOLUILENE DIAMOND COMPLETE OR PARTIAL OF A SOLVENT OR DILUENTLY USED IN A FIRST PLACE OF PRODUCTION WITH A WATER CONTENT OF 1-40% BY WEIGHT, PREFERABLY FROM 2-10% BY WEIGHT; THE MIXTURE OBTAINED IS TRANSFERRED IN A LIQUID FORM TO ANOTHER PLACE OF PRODUCTION, WHERE DRYING IS COMPLETED BY DISTILLATION OF THE TOLUILENE DIAMINE, OPTIONALLY, OTHER TREATMENT DIAMINES CAN BE ADDED FROM TOLUILEN. THE INVENTION ALSO TREATS TOLUYLENE AND WATER DIAMIN MIXTURES WITH A SOLIDIFICATION POINT OF LIKE A LOT OF 95 C AND ITS USING FOR THE OBTAINING OF TOLUYLENE DIISOCIANATE, WHICH IS PREFERRED TO A SITE, WHICH IS DIFFERENT FROM THE SITI DIAMINE OF TOLUYLENE AND WATER. |
