dichlorodifluoromethane

The propellant described in the patent is dichlorodifluoromethane, also known as Freon-12.

The main chemical used under this trademark is dichlorodifluoromethane.

The most common representative is dichlorodifluoromethane (R-12 or Freon-12).

This is a data page for dichlorodifluoromethane.

Dichlorodifluoromethane was also the main component of Silly String.

Dense gases such as xenon and dichlorodifluoromethane have low thermal conductivity.

Dichlorodifluoromethane and chlorodifluoromethane were widely used refrigerants.

Dichlorodifluoromethane with argon can be used for protective atmosphere for melting of aluminium-lithium alloys.

Halon 122 (dichlorodifluoromethane)

Other gases can be used for special applications, pure or as blend additives; e.g. sulfur hexafluoride or dichlorodifluoromethane.

Ammonia's thermodynamic properties made it one of the refrigerants commonly used prior to the discovery of dichlorodifluoromethane, normally known as Freon.

Prior to the Montreal Protocol, large quantities of carbon tetrachloride were used to produce the freon refrigerants R-11 (trichlorofluoromethane) and R-12 (dichlorodifluoromethane).

In 1930 Thomas Midgley, Jr. discovered dichlorodifluoromethane, a chlorinated fluorocarbon (CFC) known as freon.

Carbon monoxide and halogen gases (e.g. carbon tetrafluoride, sulfur hexafluoride, or dichlorodifluoromethane) require fairly high temperatures for several minutes to be effective.

Various welding or shielding gasses are available including mixtures of argon, carbon dioxide, oxygen, nitrogen, helium, hydrogen, nitric oxide, sulfur hexafluoride and dichlorodifluoromethane.

Until the 1990s, the refrigerants were often chlorofluorocarbons such as R-12 (dichlorodifluoromethane), one in a class of several refrigerants using the brand name Freon, a trademark of DuPont.

Ethylene oxide is used as a fumigant and disinfecting agent, as a mixture with carbon dioxide (8.5-80% of ethylene oxide), nitrogen or dichlorodifluoromethane (12% ethylene oxide).

Commercially it is manufactured by the reaction of fluorine with dichlorodifluoromethane or chlorotrifluoromethane; it is also produced during the electrolysis of metal fluorides MF, MF using a carbon electrode.

Tetrahalomethanes are on the border of inorganic and organic chemistry, thus they can be assigned both inorganic and organic names by IUPAC: tetrafluoromethane - carbon tetrafluoride, tetraiodomethane - carbon tetraiodide, dichlorodifluoromethane - carbon dichloride difluoride.
