Ethylene chlorohydrin, aka 2-Chloroethanol, 2-Chloroethyl alcohol, and ethylene chlorhydrin, is a colorless liquid with an ether-like odor. The compound has a boiling point at 760 mm Hg of 262 °F (128.6 °C). It is used in the manufacture of dye intermediates, pharmaceuticals, plant-protecting agents, pesticides and plasticizers. Exposure routes include inhalation, skin absorption, ingestion, skin…
A complete list of nitrogen oxides would include… Nitric oxide, aka nitrogen monoxide (NO), nitrogen(II) oxide Nitrogen dioxide (NO2), nitrogen(IV) oxide Nitrous oxide (N2O), nitrogen(−I,III) oxide Nitrosylazide (N4O), nitrogen(−I,0,I,II) oxide Oxatetrazole (N4O) Dinitrogen trioxide (N2O3), nitrogen(II,IV) oxide Dinitrogen tetroxide (N2O4), nitrogen(IV) oxide Dinitrogen pentoxide (N2O5), nitrogen(V) oxide Trinitramide (N(NO2)3 or N4O6), nitrogen(0,IV) oxides Of primary…
The classical first year chemistry definition of “pH” refers back to Danish biochemist Søren Sørenson, who originated the term, alluding to the “potential of hydrogen ion.” Specifically, pH is the negative logarithm of the molar concentration of the hydrogen ion (H+) in the particular solution. This is usually expressed as a formula… pH = -log[H+]…
Most likely, your earliest exposure to “formaldehyde” involved some sort of biological specimen, preserved in a clear liquid. This liquid was probably identified as “formaldehyde.” And, if you were in elementary school or junior high, you didn’t give it a second thought. But, if you were to study organic chemistry, you would learn that formaldehyde…
In accordance with the Clean Air Act, nitrogen dioxide (NO2) is a criteria air pollutant. Thus, it has always been of interest to the gas detection community. But, what about dinitrogen tetroxide (N2O4), a name heard primarily within the aerospace community? In that field, N2O4 is a hypergol (or hypergolic propellant). Hypergols are used in…
