Toluene Diisocyanate Production from DNT and Phosgene
This study reviews the costs associated with Toluene Diisocyanate (TDI) production from dinitrotoluene (DNT) and phosgene in the United States. Initially, DNT is hydrogenated to toluenediamine (TDA). Then, TDA reacts with phosgene in liquid phase to produce TDI.

Toluene Diisocyanate Production from DNT, CO and Methanol
This report presents the economics of Toluene Diisocyanate (TDI) production from dinitrotoluene (DNT) in the United States. The process examined is a typical reductive carbonylation. DNT initially is reacted with carbon monoxide and methanol to form toluene dimethylcarbamate, which is then thermally decomposed to produce TDI.

Toluene Diisocyanate from DNT and Cl2 (Liquid-Phase Phosgenation)
This study presents the costs associated with Toluene Diisocyanate (TDI) production from dinitrotoluene (DNT) and chlorine in the United States. Initially, DNT is hydrogenated to toluenediamine (TDA), which is reacted with phosgene in liquid phase to produce TDI. The phosgene used in this process is generated from chlorine and carbon monoxide in an on-site unit.

Toluene Diisocyanate from Toluene (Liquid-Phase Phosgenation)
This report presents the economics of a typical liquid-phase phosgenation process for Toluene Diisocyanate (TDI) production from toluene and chlorine in the USA. Initially, toluene is submitted to a dinitration to produce dinitrotoluene (DNT), which is then hydrogenated to toluenediamine (TDA). This TDA is reacted with phosgene in liquid phase to yield TDI product. The phosgene used is generated from chlorine in an on-site unit.

Toluene Diisocyanate from DNT and Cl2 (Gas-Phase Phosgenation)
This report shows a techno-economic analysis about Toluene Diisocyanate (TDI) production from dinitrotoluene (DNT) and chlorine in the United States. The process examined in this report is similar to the Bayer gas-phase phosgenation (GPP) technology. DNT is hydrogenated to toluenediamine (TDA), which then reacts with phosgene in gas phase to produce TDI. The phosgene used in generated from chlorine.

Toluene Diisocyanate from Toluene (Gas-Phase Phosgenation)
This report presents the economics of TDI production from toluene and chlorine via a process similar to the Bayer Gas-Phase Phosgenation (GPP) technology in the United States. Initially, toluene is dinitrated to dinitrotoluene (DNT). Then, DNT is hydrogenated to toluenediamine (TDA). Finally, TDA reacts with phosgene in gas phase to produce TDI. The phosgene used is generated from chlorine in an on-site unit.

Toluene Diisocyanate from Toluene (Reductive Carbonylation)
This report presents the economics of Toluene Diisocyanate (TDI) production from toluene in the United States. The process examined is a typical reductive carbonylation. Initially, dinitrotoluene (DNT) is produced via toluene dinitration, which is then reacted with carbon monoxide and methanol to form toluene dimethylcarbamate. This intermediate is thermally decomposed to produce TDI.

Toluene Diisocyanate from Toluene (Oxidative Carbonylation)
This feasibility study presents the costs associated with TDI production from toluene in the United States. The process examined is similar to Enichem's oxidative carbonylation process. In this process, DNT is hydrogenated to toluenediamine (TDA). Then, TDA reacts with dimethyl carbonate (DMC) to produce a urethane intermediate that is finally cracked to produce TDI.
