A novel preparation method of 1-fluoro-2-chloroethane, which relates to the field of fluorocarbon polymer materials, is prepared by reacting ethylene and hydrogen chloride in a cobalt trifluoride tubular fixed-bed reactor, and the synthetic route is as follows: The present invention The tubular fixed bed is used as the reactor, and ethylene, hydrogen chloride, and cobalt trifluoride are used as raw materials. The advantages are: the raw materials are all commercial products, simple equipment, easy operation, mild conditions, few steps, and high conversion rate.
Description
A kind of novel preparation method of 1-fluoro-2-chloroethane technical field The present invention relates to the field of fluorocarbon polymer materials, particularly to important intermediates for preparing PVF membrane monomers Novel preparation method of 1-fluoro-2-chloroethane. Background technique [0002] PVF films, also known as polyvinyl fluoride films, are copolymers containing fluorine or fluorocarbons with greater Chemical binding and structural stability. With crystal structure, high transparency (transparent to ultraviolet light), high electrical insulating properties, high rigidity Toughness, excellent chemical resistance, wide temperature range, aging and corrosion resistance. The monomer of polyvinyl fluoride is vinyl fluoride, because of its easy Due to the characteristics of aggregation, the safety risk in the transportation process is very large. The industrial preparation method of vinyl fluoride mainly contains two kinds: a kind of is obtaine...
