Although both methanol (CAS:67-56-1) and ethyl acetate (CAS:141-78-6) are toxic substances, current research indicates that methanol is more toxic than ethyl acetate. The primary reason is that formic acid, produced during methanol metabolism, exerts a greater impact on cells and organs.
Toxicity of Ethyl Acetate (CAS 141-78-6) and Methanol (CAS:67-56-1)
Both methanol and ethyl acetate are common organic solvents widely used in industry and daily life. However, they possess certain toxicity, and excessive ingestion or inhalation can lead to poisoning.
Methanol (CAS:67-56-1) Toxic
Methanol is a toxic, flammable liquid. It is colorless with a pungent odor and exhibits strong solubility, dissolving readily in alcohol, water, and ethanol. Methanol toxicity can affect multiple human organs, with the most severe impact being on vision. Ingested methanol is metabolized into formic acid, which further affects the eyes and optic nerves, potentially leading to blindness. Other toxic effects include impacts on the central nervous system and cardiovascular system, causing symptoms such as headaches, dizziness, nausea, vomiting, and fatigue. Severe cases may result in coma and death.
Ethyl acetate (CAS 141-78-6) toxic
Ethyl acetate is an unstable, flammable organic liquid with an aromatic odor and high volatility. As an acutely toxic substance, it can affect multiple organs upon human exposure, particularly the respiratory system and skin. Inhaling excessive ethyl acetate damages respiratory epithelial cells, causing symptoms like breathing difficulties, sore throat, coughing, and chest pain. Skin contact with ethyl acetate may cause dermatitis, irritation, sensory abnormalities, redness, swelling, blistering, and itching.
