This colorless gas is widely used as a fuel and a chemical building block. It is unstable in its pure form and thus is usually handled as a solution. Pure acetylene is odorless, but commercial grades usually have a marked odor due to impurities.
Heavily used in manufacturing of polyethylene this highly flammable hydrocarbon has a sweet and musky smell that is colourless.
Propane is one of a group of liquefied petroleum gases (LP gases). Propane is a gas, at standard temperature and pressure, but compressible to a transportable liquid. A by-product of natural gas processing and petroleum refining, it is commonly used as a fuel for engines, oxy-gas torches, portable stoves, and residential central heating.
This highly flammable hydrocarbon is colourless and used heavily in various industries, namely fuel and rubber manufacturing.
Pentanes are components of some fuels and are employed as specialty solvents in the laboratory. Their properties are very similar to those of butanes and hexanes.
Often used in coatings, inks and cleaners this glycol ether is sold by both Shell Chemical and Dow Chemical.
Often used for the formation of glues in roofing, shoes or leather products, Hexanes are colourless liquids at room temperature and odourless when pure.
A natural constituent of crude oil Benzene is classed as an aromatic hydrocarbon that is highly flammable, colourless and has a sweet smell.
Smelling like paint thinners this water-insoluble liquid is colourless and commonly found in glues subjecting it to the recreational craze of “glue sniffing”.
An aromatic hydrocarbon that is found in aircraft fuels and gasoline in small amounts.
Methanethiol is a colorless gas with a distinctive putrid smell. It is a natural substance found in the blood and brain of humans and other animals as well as plant tissues. It is disposed of through animal feces. It occurs naturally in certain foods, such as some nuts and cheese. It is also one of the main compounds responsible for bad breath and the smell of flatus. It is very flammable.
Primarily used for fumigation the gas also known as Bromomethane is non-flammable, colourless, odourless and produced both naturally as well as biologically.
Best known for its pungent putrid smell this natural, colourless gas is used to ‘stain’ other gases so their presence can be easily identified through odour.
A colourless, odourless gas flammable over a range of concentrations.
A yellow-green, toxic gas with a strong distinctive odour similar to that of household bleach.
This yellowish-green gas crystallizes as bright orange crystals at -59 °C. As one of several oxides of chlorine, it is a potent and useful oxidizing agent used in water treatment and in bleaching.
Is a colourless, odourless and also tasteless gas that is highly toxic.
A naturally occurring colourless and odourless gas, also the primary greenhouse gas.
This colorless gas gained infamy as a chemical weapon during World War I where it was responsible for about 85% of the 100,000 deaths caused by chemical weapons.
A volatile liquid that is colourless with an 'ether-like' odour.
The vapours that are emitted by diesel as it changes states at different temperatures pose varying threats to us.
Ethylene oxide is a colorless flammable gas at room temperature, with a faintly sweet odor; it is the simplest epoxide: a three-membered ring consisting of one oxygen atom and two carbon atoms.
Hydrogen is a colorless, odorless, tasteless, non-toxic, nonmetallic, highly combustible diatomic gas with the molecular formula H2.
A colourless gas also known for its ‘rotten egg’ smell. It is very poisonous, corrosive and flammable.
As a gas, formaldehyde is colorless and has a characteristic pungent, irritating odor.
HCL is a colorless gas, which forms white fumes of hydrochloric acid upon contact with atmospheric humidity. Hydrogen chloride gas and hydrochloric acid are important in technology and industry.
A colourless and extremely poisonous liquid with an odour described closely to 'bitter almonds'.
Formed from the fractionalised distillation of petroleum, this hydrocarbon based liquid is widely used for heating and the base of various jet fuels such as JP-8.
Nitrogen is a transparent, odorless diatomic gas, common element in the universe. On Earth, the element forms about 78% of Earth's atmosphere and is the most abundant uncombined element.
A colourless gas with s strong pungent odour.
Is a colourless gas with a sharp, sweet smell at room temperature.
A strong smelling gas with a reddish-brown appearance.
Required by all animals and plants for respiration, Oxygen gas is colourless, odourless and tasteless. Liquid and solid oxygen are pale blue in colour.
A pale blue gas with a distinctively pungent smell. Ozone is formed from dioxygen by the action of ultraviolet light and also atmospheric electrical discharges, and is present in low concentrations throughout the Earth's atmosphere (stratosphere).
A colourless, toxic and flammable gas that is denser than air.
A highly flammable inorganic compound that is colourless with a distinctive putrid smell.
A colourless, non-flammable toxic gas with a pungent sharp smell.
