Product Introduction

Nitrous oxide, commonly known as laughing gas or nitrous,is a chemical compound, an oxide of nitrogen with the formula N2O. At room temperature, it is a colorless non-flammable gas, with a slight metallic scent and taste. At elevated temperatures, nitrous oxide is a powerful oxidizer similar to molecular oxygen.

Nitrous oxide has significant medical uses, especially in surgery and dentistry, for its anaesthetic and pain reducing effects. Its name “laughing gas”, coined by Humphry Davy, is due to the euphoric effects upon inhaling it, a property that has led to its recreational use as a dissociative anaesthetic. It is on the World Health Organization’s List of Essential Medicines, the most effective and safe medicines needed in a health system.[2] It also is used as an oxidizer in rocket propellants, and in motor racing to increase the power output of engines.

Specification

Application

Medical
Nitrous oxide has been used in dentistry and surgery, as an anaesthetic and analgesic, since 1844

Electronic
It is used in combination with silane for chemical vapor deposition of silicon nitride layers; it is also used in rapid thermal processing to grow high quality gate oxides.

Packing&Shipping

First aid measures

INHALATION: If adverse effects occur, remove to uncontaminated area. Give artificial respiration if not

breathing. If breathing is difficult, oxygen should be administered by qualified personnel. Get immediate

medical attention.

SKIN CONTACT: If frostbite or freezing occur, immediately flush with plenty of lukewarm water (105-115 F; 41-46 C). DO NOT USE HOT WATER. If warm water is not available, gently wrap affected parts in

blankets. Get immediate medical attention.

EYE CONTACT: Flush eyes with plenty of water.

INGESTION: If a large amount is swallowed, get medical attention.

NOTE TO PHYSICIAN: For inhalation, consider oxygen.

Uses

1.Rocket motors

Nitrous oxide may be used as an oxidizer in a rocket motor. This is advantageous over other oxidisers in that it is not only non-toxic, but due to its stability at room temperature is also easier to store and relatively safer to carry on a flight. As a secondary benefit, it may be decomposed readily to form breathing air. Its high density and low storage pressure (when maintained at low temperature) enable it to be highly competitive with stored high-pressure gas systems.

2.Internal combustion engine —(Nitrous oxide engine)

In vehicle racing, nitrous oxide (often referred to as just “nitrous”) allows the engine to burn more fuel by providing more oxygen than air alone, resulting in a more powerful combustion.

Automotive-grade liquid nitrous oxide differs slightly from medical-grade nitrous oxide. A small amount of sulfur dioxide (SO2) is added to prevent substance abuse. Multiple washes through a base (such as sodium hydroxide) can remove this, decreasing the corrosive properties observed when SO2 is further oxidised during combustion into sulfuric acid, making emissions cleaner.

3.Aerosol propellant

The gas is approved for use as a food additive (also known as E942), specifically as an aerosol spray propellant. Its most common uses in this context are in aerosol whipped cream canisters, cooking sprays, and as an inert gas used to displace oxygen in order to inhibit bacterial growth when filling packages of potato chips and other similar snack foods.

Similarly, cooking spray, which is made from various types of oils combined with lecithin (an emulsifier), may use nitrous oxide as a propellant. Other propellants used in cooking spray include food-grade alcohol and propane.

4.Medicine——–Nitrous oxide (medication)

Nitrous oxide has been used in dentistry and surgery, as an anaesthetic and analgesic, since 1844.

Nitrous oxide is a weak general anaesthetic, and so is generally not used alone in general anaesthesia, but used as a carrier gas (mixed with oxygen) for more powerful general anaesthetic drugs such as sevoflurane or desflurane. It has a minimum alveolar concentration of 105% and a blood/gas partition coefficient of 0.46. The use of nitrous oxide in anaesthesia, however, can increase the risk of postoperative nausea and vomiting.

In Britain and Canada, Entonox and Nitronox are used commonly by ambulance crews (including unregistered practitioners) as a rapid and highly effective analgesic gas.

50% nitrous oxide can be considered for use by trained non-professional first aid responders in prehospital settings, given the relative ease and safety of administering 50% nitrous oxide as an analgesic. The rapid reversibility of its effect would also prevent it from precluding diagnosis.

5.Recreational use

Recreational inhalation of nitrous oxide, with the purpose of causing euphoria and/or slight hallucinations, began as a phenomenon for the British upper class in 1799, known as “laughing gas parties”.

In the United Kingdom, as of 2014, nitrous oxide was estimated to be used by almost half a million young people at nightspots, festivals, and parties. The legality of that use varies greatly from country to country, and even from city to city in some countries.
