5000 ppm: 75434: 594-72-9: 0434: Dichloronitroethane: 147.3 mg/m 3: 25 ppm: 594729: 76-14-2: ... n-Hexane: 3883 mg/m 3: 1100 ppm: 110543 (10% Lower explosive limit ...
The current n-hexane PEL in the US is 500 ppm (1,800 mg/m 3 (0.79 gr/cu ft)). [24] Hexane and other volatile hydrocarbons (petroleum ether) present an aspiration risk. [26] n-Hexane is sometimes used as a denaturant for alcohol, and as a cleaning agent in the textile, furniture, and leather industries. It is slowly being replaced with other ...
Phase behavior Triple point: 178.0 K (–95.1 °C), 1.23 Pa Critical point: 507.6 K (234.5 °C), 3020 kPa Std enthalpy change of fusion, Δ fus H o: 13 kJ/mol
Chemicals that occur in TPH include hexane, benzene, toluene, xylenes, naphthalene, and fluorene, other constituents of gasoline, jet fuels, mineral oils, and of other petroleum products. [1] Petroleum hydrocarbon ranges are monitored at various levels depending on the state and testing site.
These results suggest that other components found in petroleum benzine may have additive, synergistic or potentiative effects on the biological effects of n-hexane. [7] Namely, 1000 ppm n-hexane, 3000 ppm n-heptane, and 1000 ppm toluene were reported to have depressing effects on the body weight gain of rats. [8]
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Since November, the FBI has received tips involving over 5,000 reported drone sightings, resulting in mounting anxiety among residents spotting what they believe to be Unmanned Aircraft Systems (UAS).
Atmospheric pollutant concentrations expressed as mass per unit volume of atmospheric air (e.g., mg/m 3, μg/m 3, etc.) at sea level will decrease with increasing altitude because the atmospheric pressure decreases with increasing altitude.
