Experts of New Chemical Products LLC have developed and tested the synthesis of a number of fluoroorganic compounds:
- tetrafluoromethane and other fluoromethanes by the fluorination of methane with fluorine in the gas-liquid reactor,
- perfluoroalkanes (tetrafluoromethane, hexafluoroethane, octafluoropropane, decafluorobutane) by fluorination of graphite with fluorine,
- pentafluoroethane by gas-phase fluorination of asymmetric tetrafluoroethane by fluorine.
The development of new technologies for the synthesis of fluorine organic compounds was due to the need to avoid using prohibited ozone-depleting compounds as raw materials or intermediates.
The ozone layer is a part of the atmosphere at an altitude from 20 to 25 km with the highest content of ozone O3 formed as a result of the action of ultraviolet radiation from the Sun on molecular oxygen (O2). At the same time, due to the processes of oxygen dissociation whose atoms then form ozone, ultraviolet absorption of the solar spectrum takes place with the highest intensity.
The Montreal Protocol on Substances that Deplete the Ozone Layer is an international protocol to the 1985 Vienna Convention for the Protection of the Ozone Layer, designed to protect the ozone layer by removing certain ozone depleting chemical substances, mainly fluorine and chlorine-containing organic compounds.
