Laughing gas

Laughing gas is a colourless and odourless gas condensed to liquid under pressure. The gas is narcotic, oxidising and oxygen suppressant. Laughing gas is mainly used as a propellant gas in the food industry (amongst other for the whipping cream). In high quality, laughing gas is used in the electronics and semiconductor industry.

Physicochemical constants

Symbol	N2O
Average molecular weight (kg/mol)	44.01
Density of the gas (kg/m3 at 1.013 bar and 0 °C)	1.98
Relative density of the gas (air = 1)	1.531
Boiling point	- 88.5 °C (184.7 K)
Critical temperature	t = 36.4 °C (309.6 K)
Vapour pressure (bar at 20 °C)	51
Density gas phase (kg/m3) - at 0 °C - 1 bar	1.978
Self-ignition temperature	Not flammable but oxidising

1 litre liquid N₂O releases 540 litres gas at 15 °C. and 1 bar.

Application areas

Other applications:

• As propellant gas in the food industry, with coffee concentrates, in the pharmaceutical industry, with beauty products and products for household maintenance
• As detector of leaks in vacuum rooms by means of infrared spectrophotometry

Equipment

Piping systems are pressure and product-linked and must be taken care of by competent people taking into consideration the current standards and legislation. Each gas with its specific purity requires suitable material. IJsfabriek Strombeek can provide you the appropriate material for every application such as: mufflers, flow meters, filters, valves, pressure gauges...
