TDI (Toluene Di-Isocyanate) is widely used in the production of polyurethanes and it is to be handled carefully due to its toxic effects on the human health and environment. TDI spills and leftovers are to be treated with extreme care in order to avoid human exposure to the toxic gases and wastes. It is necessary to neutralize or convert the reactive isocyanate groups of the spills or leftover of TDI into harmless compounds. This report elaborately describes the effects of TDI on human health and also the reactions of TDI with important functional groups and chemicals like amines, alcohols and water. This report also brings out the neutralization methods available for treatment of the minor spills and leftover of TDI.
