What is the boiling point of acetonitrile?
179.6°F (82°C)
Acetonitrile/Boiling point
Does acetonitrile evaporate at room temperature?
if you put the heating bath of your rotavap to 40°C, Acetonitrile will start evaporating @ approx. 90 mbar; if the pressure decreases to about 40 mbar, the AcN is gone.
Is acetonitrile heavier than air?
It dissolves easily in water. It can react with water, steam or acids to produce flammable vapors that can form explosive mixtures when exposed to air. The vapors are heavier than air and can travel to low or confined areas.
What is the vapor pressure of acetone?
185.5 mm Hg
The vapor pressure of acetone at 20°C is 185.5 mm Hg, and the vapor pressure of water at this same temperature is 17.5 mm Hg.
What is the normal boiling point of ch3no2?
212°F (100°C)
Nitromethane/Boiling point
What is the freezing point of acetonitrile?
-49°F (-45°C)
Acetonitrile/Melting point
Is acetonitrile miscible with water?

Why does nitromethane make so much power?
The fuel comes with its own oxygen atoms to help it burn. The big advantage of nitromethane is that you can get a lot more power from each explosion inside the engine. This means that, compared to gasoline, you can pump about 8 times more nitromethane into a cylinder of a given volume and still get complete combustion.
What is the flammability envelope of acetonitrile vapor?
Vapor mixtures of Acetonitrile and air containing between 4.4 and 16 percent Acetonitrile at 25°C are potentially flammable. This flammability “envelope” is a function of temperature, pressure and the concentration of oxygen in the vapor. The flammability envelope for Acetonitrile at 40-45°C is shown in Figure 2.9.
Why is acetonitrile less toxic than other nitriles?
Formaldehyde, a toxin and a carcinogen on its own, is further oxidized to formic acid, which is another source of toxicity. The metabolism of acetonitrile is much slower than that of other nitriles, which accounts for its relatively low toxicity.
What does the flash point of acetonitrile look like?
Acetonitrile appears as a colorless limpid liquid with an aromatic odor. Flash point 42°F. Density 0.783 g / cm3. Toxic by skin absorption. Less dense than water. Vapors are denser than air.
Where can you find acetonitrile in the air?
Acetonitrile has many uses, including as a solvent, for spinning fibers, and in lithium batteries. It is primarily found in air from automobile exhaust and manufacturing facilities. Acute (short-term) inhalation exposure results in irritation of mucous membranes.
