Nitrous oxide, also known as dinitrogen monoxide, nitrogen protoxide, nitrous, nitro, NOS or more popular laughing gas is a chemical compound with the formula N2O.

PropertiesEdit

ChemicalEdit

Nitrous oxide is an oxidizer. Unlike other nitrogen oxides, nitrous oxide does not react with water to form nitric acids.

PhysicalEdit

Nitrous oxide is a colorless, non-flammable gas, with a slightly sweet odor and taste. It is poorly soluble in water, but more soluble in several organic solvents such as ethanol, diethyl ether, as well as sulfuric acid. It is known as "laughing gas" due to the euphoric effects of inhaling it, a property that has led to its recreational use as a dissociative anaesthetic.

AvailabilityEdit

Nitrous oxide is available as whippets.

PreparationEdit

Nitrous oxide is prepared by the careful decomposition of ammonium nitrate, which results in nitrous oxide and water vapor.

NH4NO3 → N2O + 2 H2O

Due to the very low amount of secondary products, this reaction is preferred by many chemists.

Another way of preparing nitrous oxide involves heating a mixture of ammonium sulfate and sodium nitrate.

2 NaNO3 + (NH4)2SO4 → Na2SO4 + 2 N2O+ 4 H2O.

Another route involves heating a mixture of urea, nitric acid and sulfuric acid between 40-100°C and purifying N2O from resulting gaseous products:

2 (NH2)2CO + 2 HNO3 + H2SO4 → 2 N2O + 2 CO2 + (NH4)2SO4 + 2 H2O[1]

HandlingEdit

SafetyEdit

Nitrous oxide has low toxicity and posses analgesic properties. Nitrogen protoxide is a strong oxidizer and should be kept away from any combustible materials.

When obtaining it from ammonium nitrate, it's imperative to prevent the temperature from rising too high, as it may cause an explosion if large quantities are used. This isn't an issue with commercial AN, as it contains gypsum which acts as a stabilizer and reduces the risk of explosion.

StorageEdit

Nitrous oxide cylinders should be stored in cold places, away from any organic materials, as it is a strong oxidizer and a fire hazard.

DisposalEdit

Nitrous oxide will eventually break down in air into nitrogen and oxygen, and does not generate any toxic byproducts. This reaction is sped up by reducing agents.
