Abstract

The present communication provides an effective methodology which is simple, time saving and economical in order to have a safe, healthy and friendly process environment in plant. The toxicology and environmental effects of Toluene Diisocyanate (TDI) is exposed during process operations and is highly concerned from the environmental protection point of view. In almost every-scenario, the threat of environmental exposure is contingent upon the proper handling of this chemical. This chemical is colorless to pale yellow liquid, found responsible for asthma, lung damage, and severe cases fatal reactions. Ordinary discharge of waste containing TDI in the environment leads to imbalance of the ecosystem due to the presence of considerable amount of free Isocyanates. The paper deals with suitable formulation of isopropyl alcohol, rectified spirit (95%ethanol), dilute ammonia and soap solution to neutralize free TDI and then its presence was confirmed through spectroscopic technique. The formulations are promising eco-friendly neutralizing agent which neutralizes the available TDI within 24 hours only.
