Methyl isocyanate (MIC) is an organic compound with the molecular formula CH 3 NCO. Synonyms are isocyanatomethane and methyl carbylamine. Methyl isocyanate is an intermediate chemical in the production of carbamate pesticides and Haffmann Bromamide Degradation (such as carbaryl, carbofuran, methomyl, and aldicarb).

Most city residents who were exposed to the MIC gas were first made aware of the leak by exposure to the gas itself, or by opening their doors to investigate commotion, rather than having been instructed to shelter in place or to evacuate before the arrival of the gas in the first place.

Gaseous methyl isocyanate is approximately 1.4 times heavier than air. Methyl isocyanate liquid is colorless with a pungent odor. Most people can smell methyl isocyanate vapors at levels as low as 2 to 5 ppm. Methyl isocyanate is handled and transported as …

The subcutaneous administration of methyl isocyanate (MIC) in 1.0 LD50 dose in rats caused a significant effect on hepatic mitochondrial function only at complex I region of the respiratory chain. MIC administration at 1.0 LD50 dose also resulted in significant increases in malondialdehyde and ferrous ion

2015年1月1日 · MIC is the smallest and the most toxic of all isocyanates; it affected all life forms, killed nearly 8,000 people within 48 hours by producing pulmonary edema, and produced lasting effects on more than 200,000 residents.

What Is MIC? MIC (methyl isocyanate) is a volatile, colorless liquid that is extremely flammable, and potentially explosive when mixed with air. MIC reacts with water, giving off heat and producing methylamine and carbon dioxide. The liquid and vapor are toxic when inhaled, ingested, or exposed to the eyes or skin.

2021年1月1日 · MIC is a colorless low boiling liquid, highly flammable, with a sharp, unpleasant odor. It is a highly reactive gas that violently undergoes an exothermic reaction with water to produce carbon dioxide, dimethylurea, and trimethylbiuret.

Methyl isocyanate (MIC) is an organic compound with the molecular formula CH3 NCO. MIC is an extremely toxic, colorless, highly flammable liquid that evaporates quickly when exposed to the air and has a sharp, strong odor.

Methyl isocyanate (MIC) will react with water, or in the presence of catalysts (such as sodium hydroxide, sodium methoxide, triphenylarsine, triethyl phosphine, metallic chlorides) to form either a cyclic trimer (trimethyl isocyanurate) or a gummy, resinous polymer.

2024年12月4日 · The Bhopal Gas Tragedy, which occurred on the night of December 2–3, 1984, in Bhopal, India, is one of the most devastating industrial disasters in history. The gas leak from a pesticide plant owned by Union Carbide India Limited (UCIL) released a highly toxic cloud of methyl isocyanate (MIC) gas, causing widespread death, injury, and suffering.
