It is produced by fluorination of chloroform using a catalyst such as antimony trifluoride: CHCl3 + HF → CHCl2F + HCl Dichlorodifluoromethane (R-12) is a colorless gas usually sold under the brand name Freon-12, and a chlorofluorocarbon halomethane (CFC) used as a refrigerant and aerosol spray propellant. Complying with the Montreal Protocol, its manufacture was banned in developed countries (non-article 5 countries) in 1996, and in developing countries (Article 5 countries) in 2010 out of concerns about its damaging effect on the ozone layer. Its only allowed usage is as a fire retardant in … how 2 make anvil

It is an anhydrous solvent, which minimizes any interference from water peaks. It is useful in performing critical air- and moisture-sensitive NMR analysis. It may be synthesized by reacting trichloroacetophenone and sodium deuteroxide. [ 1] WebOver 200,000 approved drugs and health products.
