제품 상세 정보

메틸벤젠, an organic compound, is a colorless, volatile liquid with a distinctive aroma. It has strong refraction. It is miscible with ethanol, 에테르, acetone, chloroform, carbon disulfide and glacial acetic acid, and very slightly soluble in water. 가연성, vapor can form an explosive mixture with air, and the mixture can explode when the volume concentration is in a low range. Low toxicity, median lethal dose (rats, orally) 5000mg/kg. High concentrations of gas are anesthetic and irritating.
