| | 2-METHYL-M-PHENYLENE DIISOCYANATE Usage And Synthesis |
| Chemical Properties | colourless liquid | | General Description | Liquid. Used in the manufacture of polyurethane foams, elastomers, and coatings; crosslinking agent for nylon 6. | | Reactivity Profile | 2-METHYL-M-PHENYLENE DIISOCYANATE reacts violently with amines, alcohols, bases and warm water, causing fire and explosion hazards. [Handling Chemcials Safely 1980. p. 907]. Reaction with water to form Carbon Dioxide [Merck 11th ed. 1989]. | | Health Hazard | Classified as slightly toxic orally. Probable oral lethal dose in humans is 5 to 15 g/kg or between 1 pint and 1 quart for a 70 (l50 lb.) person. Particularly poisonous when breathed. This is among the most poisonous of isocyanates. Acute and chronic exposures to low concentrations may produce asthmatic attacks. | | Fire Hazard | When heated to decomposition, 2-METHYL-M-PHENYLENE DIISOCYANATE emits toxic fumes of nitrogen oxides. Ventilation should be adequate. If polyurethane products are heated, protection against isocyanate release is necessary. Avoid decomposing heat. |
