Full Answer

Freon 11 was also used as a propellant for aerosols until the 1970s, when it was banned because of its harmful effects to the ozone layer. Most equipment produced in the '90s that used Freon 11 is being replaced by its more environmentally-friendly substitute, R-123. Even though it is less harmful, even R-123 is set to be discontinued in 2020.

    What is carbon dioxide used for?

    A:

    Carbon dioxide has applications as a refrigerant and coolant in many different industries. It acts as a chemical precursor in the industrial production of urea and methanol and is a common shielding gas for inert gas welding processes. Beverage manufacturers use carbon dioxide to produce carbonated drinks such as soda, beer and sparkling wine. Commercial wine producers also use solid carbon dioxide, also known as dry ice, to cool grapes quickly following a harvest, as this prevents spontaneous fermentation.

    What does Freon gas smell like?

    A:

    Freon gases have a sweet odor similar to ether or freshly mowed grass. The odor becomes noticeable at concentrations of higher than 20 percent. At 11 percent concentration and higher, Freon gases are toxic, so the effects can become debilitating before the odor is detected.

    Freon is an odorless gas; it does not smell like anything. Freon is a popular refrigerant because it is non-toxic and non-flammable. Although it dates back to 1928, Freon and its related gases are still the safest refrigerants on the market. It is also an effective aerosol propellant, but is no longer used for this purpose.
