용도
개요
Vinyl fluoride (VF) was first synthesized by Frederic Swarts, a Belgian chemist in 1901, by the reaction between zinc and 1,1-difluoro-2-bromoethane. Modern preparation involves the reaction of acetylene and hydrogen fluoride (HF) in the presence of a mercury- or aluminum-based catalyst. The US Environmental Protection Agency (EPA) listed VF as a highproduction- volume chemical in 1990. According to National Toxicology Program (NTP), 2005, the annual production of VF in the United States was above 1 million pounds (454 000 kg) in 1990 and approximately 3.3 million pounds (1.5 million kg) in 2001.
용도
Vinyl fluoride is used primarily in the production of polyvinyl fluoride and other fluoropolymers. Polymers of vinyl fluoride are resistant to weather and exhibit great strength, chemical inertness, and low permeability to air and water. Polyvinyl fluoride is laminated with aluminum, galvanized steel, and cellulose materials and is used as a protective surface for the exteriors of residential and commercial buildings. Polyvinyl fluoride laminated with various plastics has been used to cover walls, pipes, and electrical equipment and inside aircraft cabins (IARC 1995).
일반 설명
A colorless gas with a faint ethereal odor. Shipped as a confined liquid under its vapor pressure. Any leak can either be liquid or vapor. Contact with the liquid can cause frostbite. Easily ignited. Vapors are heavier than air. Can asphyxiate by the displacement of air. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket.
제조 및 합성 방법
생산 방법
The first preparation of VF in the early 1900s was by reacting zinc with 1,1-difluoro-2-bromomethane. VF was considered to be a high production volume chemical according to the U.S. Environmental Protection Agency with annual production exceeding 1million lb in 1990. In 2001, annual U.S. production was estimated approximately 3.3 million lb. In 1994, VF was produced by one company each in Japan and the United States. More recently, only one U.S. manufacturer of VF was identified . Information on European manufacturer is not available. The modern production is by the addition of hydrogen fluoride to acetylene over a mercury- or aluminum-based catalyst.
제조 방법
Vinyl fluoride may be obtained from acetylene by either of the two following routes:In the first method, acetylene is heated with hydrogen fluoride in the presence of a catalyst of mercuric chloride on charcoal at about 40C to yield vinyl fluoride directly. In the second method, acetylene is treated with an excess of hydrogen fluoride to form difluoroethane which is then pyrolysed at about 700C in a platinum tube to give vinyl fluoride, which is separated by distillation under pressure.Vinylidene fluoride is obtained from vinylidene chloride by the following route:In the first stage, vinylidene chloride undergoes addition with hydrogen chloride at about 30C and atmospheric pressure in the presence of a FriedelCrafts type catalyst. The resulting trichloroethane is then treated with hydrogen fluoride at about 180C and 3 MPa (30 atmospheres) in the presence of antimony pentachloride to give chlorodifluoroethane. Pyrolysis of this product yields vinylidene fluoride. Vinylidene fluoride is a gas, b.p. -84C.
