WebMIC is extremely toxic to humans from acute (short-term) exposure. It is a colorless liquid with a sharp pungent odor. MIC is prepared industrially by reacting methylamine with phosgene, oxidizing monomethylformamide at high temperatures (>550 °C), or heating metal MICs. MIC is also manufactured from N -methylformamide and air. WebDue to lower water solubility than other irritant gases (e.g. Chlorine gas), phosgene causes less immediate irritation of the mucous membranes and therefore is able to penetrate to and damage the lower respiratory tract Immediate effects (depends on concentration) - mucous membrane irritation, tachypnea, shallow breathing
