Toluene diisocyanate (TDI) is an aromatic diisocyanate. It is produced for reaction with polyols to form polyurethanes. It exists in two isomers, 2, 4-TDI (CAS: 584-84-9) and 2, 6-TDI (CAS: 91-08-7). 2, 4-TDI is produced in the pure state, but TDI is often marketed as 80/20 and 65/35 mixtures of the 2, 4 and 2, 6 isomers respectively. It is a highly produced diisocyanate, accounting for 34.1% of the global isocyanate market in 2000, second only to MDI.[1] All major producers of TDI are members of the International Isocyanate Institute, whose aim is the promotion of the safe handling of TDI in the workplace, community and environment.
