N2O(Laughing gas)

Nitrous oxide, commonly known as laughing gas, nitrous, or factitious air, among others, is a chemical compound, an oxide of nitrogen with the formula N ₂O. At room temperature, it is a colourless non-flammable gas, and has a slightly sweet scent and taste.     

Nitrous Oxide Applications：

Nitrous oxide is the main scavenger of stratospheric ozone, with an impact comparable to that of chlorofluorocarbons. Nitrous oxide is used as a propellant in a wide range of applications, from rocket launches to making whipped cream. Nitrous oxide can act on the central nervous system, and long-term or high-dose use can cause brain hypoxia, resulting in nervous system damage, as well as drowsiness, depression or mental confusion, which can even be life-threatening in severe cases.
Medical Applications：
Nitrous oxide has a wide range of applications in the medical field. It was first used for anesthesia in dental surgery and has gradually expanded to surgical and obstetric and gynecological surgery. Nitrous oxide has a mild anesthetic effect that can relieve the patient's pain while keeping the patient awake. In addition, nitrous oxide is also used for painless delivery during childbirth, by inhaling a mixture of a certain proportion of nitrous oxide and oxygen to relieve the pain during childbirth.
Food processing applications
In the field of food processing, nitrous oxide is mainly used to make whipped cream. It can help the cream to be whipped better and make the cake taste more delicate. In addition, nitrous oxide can also be used as a food preservative to extend the shelf life of food.
Industrial Applications
Nitrous oxide is mainly used as a propellant and combustion aid in the industrial field. It can be used in rocket and racing car engines to increase power output. In addition, nitrous oxide can also be used to produce nitric acid, synthetic urea and other chemical raw materials.
Research Applications
In the field of scientific research, nitrous oxide is used as a raw material for chemical reactions and participates in a variety of chemical reactions. It can also be used to manufacture electronic devices such as semiconductors and liquid crystals. In addition, nitrous oxide is also used in atomic absorption spectroscopy analysis.
Environmental Applications
Nitrous oxide is a powerful greenhouse gas, with a greenhouse effect 296 times that of carbon dioxide. Therefore, its emissions need to be controlled to protect the environment.
