Toluene diisocyanate

This final step produces HCl as a byproduct and is a major source of industrial hydrochloric acid.

The two isocyanate groups in Toluene diisocyanate react at different rates: The 4-position is approximately four times more reactive than the 2-position.

[3] Toluene diisocyanate is used in the production of rigid polyurethane foams with a high temperature stability.

[4] This is due to the high pulmonary risk of prolonged exposure at low doses.

[7] Information is available on handling, personal protective equipment, exposure monitoring, transport, storage, sampling and analysis of TDI, dealing with accidents, and health and environmental themes.

NFPA 704 four-colored diamond Health 3: Short exposure could cause serious temporary or residual injury. E.g. chlorine gas Flammability 1: Must be pre-heated before ignition can occur. Flash point over 93 °C (200 °F). E.g. canola oil Instability 1: Normally stable, but can become unstable at elevated temperatures and pressures. E.g. calcium Special hazards (white): no code
