2010/03/15. 11.1. 2017 Dec;59 Suppl 12:S22-S27. Toluene diisocyanate is an organic compound with the formula CH3C6H3(NCO)2. Approximately 1.4 billion kilograms were produced in 2000. 2,4-Toluene diisocyanate is used as a chemical intermediate in the production of polyurethane products . TDI) is an organic compound, in the aromatic isocyanate class. 10. 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.

Bayer has recently developed a new phosgenation technology to produce toluene diisocyanate (TDI).
An organic compound with two isocyanate groups is known as a diisocyanate. Published October 2009. 1.

11. It is produced on a large scale, accounting for 34.1% of the global isocyanate market in 2000, second only to MDI. Occupational exposure to 2,4-toluene diisocyanate can occur for those workers involved in its manufacture . The main commercial route for the manufacture of TDI starts with the nitration of toluene using nitric acid to produce dinitrotoluene followed by catalytic hydrogenation to toluene diamine. such as foams, coatings, and elastomers. – Toluene diisocyanate production technology, specification – Toluene diisocyanate production capacity and plants, share in the global industry – Recent company activities in toluene diisocyanate market.

Isocyanate is the functional group with the formula R−N=C=O. Integrated Production of Toluene Diisocyanate from Toluene PEP Review 2009-3. TOLUENE DIISOCYANATE FEEDSTOCK MARKET. (3) Sources and Potential Exposure . 1.1 Isocyanates. All isomers of TDI are colorless, a doi: 10.1097/JOM.0000000000000890. Incidence of Occupational Asthma and Exposure to Toluene Diisocyanate in the United States Toluene Diisocyanate Production Industry. Organic compounds that contain an isocyanate group are referred to as isocyanates. … Many of the products we rely upon every day are safer and more comfortable through the use of polyurethanes made possible by diisocyanates. J Occup Environ Med. B. Klesczewski, in Encyclopedia of Materials: Science and Technology, 2001. Toluene Di-isocyanate (TDI) Production and Manufacturing Process. Diisocyanates are a family of chemical building blocks mainly used to make polyurethane products, such as rigid and flexible foams, coatings, adhesives, sealants and elastomers. Two of the six possible isomers are commercially important: 2,4-TDI and 2,6-TDI.
