“…Phosgene (PhG), methyl isocyanate (MIC), hydrochloric acid (HCl) and chloroform (TCM) are a class of volatile organic compounds (VOCs) which play a crucial role as chemical precursors in the polyurethane and pesticides industries. [1][2][3][4][5] PhG is known to be employed in a variety of industrial-scale organic syntheses, as a raw material in deriving a variety of important intermediates that are subsequently used in the preparation of pharmaceuticals, dyes, and pesticides. 6,7 TCM, MIC and HCl are important reactants in the production of isocyanates, a crucial intermediate in the manufacture of polyurethane and pesticides.…”
