2024年5月10日 · What are the stability and reactivity hazards of toluene? What are unintentional release measures for toluene? What handling and storage practices should be used when working with toluene? What is the American Conference of Governmental Industrial Hygienists (ACGIH®) recommended exposure limit for toluene?
Toluene CCOHS. Flammable liquids - Category 2. Acute toxicity - inhalation - Category 4. Skin corrosion/irritation - Category 2
Converting Occupational Exposure Limits from mg/m³ to ppm
To convert mg/m 3 to ppm at other temperatures and pressures, one must calculate the volume of one gram molecular weight of the airborne contaminant (e.g., 92.13 grams of toluene) at that temperature and pressure by using the ideal gas law formula: PV = nRT

2023年2月6日 · Examples of lipophilic substances with a molecular weight less than 500 g/mole (Daltons) are solvents such as hexane, benzene, toluene, styrene, chlorinated solvents (e.g., chloroform, tetrachloroethylene, carbon tetrachloride, methylene chloride), etc.
Solvents and fuels produced from petroleum (e.g., benzene, toluene, mineral spirits, gasoline, jet fuel) can build up a charge when they are poured or flow through hoses. They tend to hold. a charge because they cannot conduct electricity well enough to discharge when in contact
