Toluene Diisocyanate TDI
Toluene Diisocyanate (TDI) CAS:584-84-9 Toluene Diisocyanate is produced by a 3 step reaction. The first step is the nitration of toluene to obtain dinitrotoluene. Second step is the catalytic hydrogenation of Dinitrotoluene into toluene diamine TDA. Finally, the TDA react with phosgene to produce the TDI. TDI is commonly sold under 3 different ratio isomeric […]
