• 개요

  Formaldehyde is a colorless, flammable gas with a distinctive pungent odor. It is the simplest aldehyde, which is a class of organic compounds with the carbonyl group bonded to at least one hydrogen atom. Formaldehyde was described by August Wilhelm von Hoff mann (1818–1892) in 1867 after the Russian Aleksandr Butlerov (1828–1886) had inadvertently synthesized it in 1857. Formaldehyde readily dissolves in water to produce a solution called formalin, which is commonly marketed as a 37% solution.

• 화학적 성질

  Formaldehyde is an important chemical widely used by industry to manufacture building materials and numerous household products. It is also a by-product of combustion and certain other natural processes. It is present in substantial concentrations both indoors and outdoors. Formaldehyde is well known as a preservative in medical laboratories, as an embalming fl uid, and as a sterilizer. Its primary use is in the production of resins and as a chemical intermediate. Urea formaldehyde (uf) and phenol formaldehyde (pf) resins are used in foam insulations, as adhesives in the production of particle board and plywood, and in the treating of textiles. Sources of formaldehyde in the home include building materials, smoking, household products, and the use of unvented, fuel-burning appliances, like gas stoves or kerosene space heaters. Formaldehyde, by itself or in combination with other chemicals, serves a number of purposes in manufactured products. It has been reported that the use and production of formaldehyde in 1998 was about 11.3 billion pounds and the international production crossed over 46 billion pounds in 2004.

• 물리적 성질

  Formaldehyde is a clear, colorless liquid with a pungent, suffocating odor. Burning taste. Experimentally determined odor threshold concentrations of 1.0 ppmv and 0.50 ppmv were reported by Leonardos et al. (1969) and Nagata and Takeuchi (1990), respectively. Also,formalin is an aqueous solution that is 37% formaldehyde by weight; inhibited solutions (added to prevent polymeri zation) usually contain 6 12% methyl alcohol. Formaldehyde is used in the manufacture of plastics and resins by reaction with phenols,urea, and melamine. It is used as a preservative,a disinfectant, and as a chemical intermediate.

• 역사

  Formaldehyde is a by-product of combustion of organic compounds, metabolism, and other natural processes. Formaldehyde results from wood combustion and elevated atmospheric concentrations can result from forest fires, as well as from urban pollution sources such as transportation. Formaldehyde has been identified as a significant indoor air pollutant. Building materials such as particleboard, plywood, and paneling are major sources of formaldehyde because they incorporate formaldehyde resins as bonding adhesives. Other sources of formaldehyde in the home are carpets, upholstery, drapes, tobacco smoke, and indoor combustion products. Formaldehyde may be emitted from building materials for several years after installation. In the two decades of the 1960s and 1970s, a half million homes in the United States used urea formaldehyde foam insulation, but health complaints led to its elimination as an insulator in the early 1980s. People react differently to formaldehyde exposure, but it is estimated that between 10% and 20% of the population will experience some reaction at concentrations as low as 0.2 parts per million. Formaldehyde irritates the eyes, nose, and throats, producing coughing, sneezing, runny nose, and burning eyes. More severe reactions result in insomnia, headaches, rashes, and breathing difficulties. Some states have established indoor air quality standards ranging from 0.05 to 0.5 ppm.

• 용도

  Formaldehyde is used in the manufactureof phenolic resins, cellulose esters, artificialsilk, dyes, explosives, and organic chemicals.Other uses are as a germicide, fungicide, anddisinfectant; in tanning, adhesives, waterproofingfabrics, and for tonic and chromeprinting in photography; and for treating skindiseases in animals. In vitro neutralizationof scorpion venom toxicity by formaldehydehas been reported (Venkateswarlu et al.1988).
  Formaldehyde constitutes about 50% ofall aldehydes present in the air. It is oneof the toxic effluent gases emitted fromburning wood and synthetic polymeric substancessuch as polyethylene, nylon 6, andpolyurethane foams. Firefighters have a greaterrisk to its exposure. Incapacitation fromthe toxic effluent gases is reported to occurmore rapidly from the combustion of syntheticpolymers than from that of naturalcellulose materials.
  Formaldehyde is directly emitted into theair from vehicles. It is released in traceamounts from pressed wood products suchas particleboard and plywood paneling, fromold “sick” buildings, and from cotton andcotton–polyester fabrics with selected crosslinkfinishes. Formation of formaldehyde hasbeen observed in some frozen gadoid fishdue to enzymic decomposition of the additivetrimethylamine oxide (Rehbein 1985).Its concentration can build up during frozenstorage of fish (Leblanc and Leblanc 1988;Reece 1985). It occurs in the upper atmosphere,cloud, and fog; it also forms inphotochemical smog processes.

• 정의

  Formalin: a colourless solution of methanal (formaldehyde) in waterwith methanol as a stabilizer; r.d.1.075–1.085. When kept at temperaturesbelow 25°C a white polymer ofmethanal separates out. It is used asa disinfectant and preservative forbiological specimens.

• 생산 방법

  The industrial preparation of formaldehyde has occurred since the late 1800s and involvesthe catalytic oxidation of methanol: 2CH₃OH(g) + O₂(g) → 2CH₂O(g).the oxidationtakes place at temperatures between 400°C and 700°C in the presence of metal catalysts. Metalsinclude silver, copper, molybdenum, platinum, and alloys of these metals. Formaldehyde iscommonly used as an aqueous solution called formalin. Commercial formalin solutions varybetween 37% and 50% formaldehyde. When formalin is prepared, it must be heated anda methanol must be added to prevent polymerization; the final formalin solution containsbetween 5% and 15% alcohol.

• 제조 방법

  Formalin is adjusted to pH 8 and urea is added to give a urea to formaldehyde ratio of about 1 :2.5 molar. The resulting solution is boiled under reflux for 1 hour. Butanol (1.5-2.0 mole per mole of urea) is then added together with a little xylene. The latter forms, with butanol and water, a ternary azeotrope which on distillation yields a condensate separating into an upper organic layer and a lower aqueous layer. By discarding the lower layer and returning the upper layer to the reactor, water is progressively removed from the system. After a substantial proportion of the water has been removed, an acid catalyst (e.g. phosphoric acid or phthalic anhydride) is added and heating is continued. When the required degree of reaction is attained, the solution is neutralized and concentrated to the desired solids content.

• 일반 설명

  Formaldehyde solution commercially formaldehyde solution is an aqueous solution containing 37% formaldehyde and 8-10% methanol. Formaldehyde solution can be activated by adding the catalytic amount of lanthanide triflate. This activated formaldehyde solution was employed for the smooth hydroxymethylation reaction of silyl enol ethers. Formaldehyde solution reacts with silyl enol ethers to afford the corresponding hydroxymethylated adducts in high yields.

  Moderate fire risk. Explosive limits in air 7– 73%. Toxic by inhalation, strong irritant, a carcinogen. (Solution) Avoid breathing vapor and avoid skin contact. Confirmed carcinogen.

• 건강위험

  Formaldehyde is moderately toxic by skin contact and inhalation. Exposure to formaldehyde gas can cause irritation of the eyes and respiratory tract, coughing, dry throat, tightening of the chest, headache, a sensation of pressure in the head, and palpitations of the heart. Exposure to 0.1 to 5 ppm causes irritation of the eyes, nose, and throat; above 10 ppm severe lacrimation occurs, burning in the nose and throat is experienced, and breathing becomes difficult. Acute exposure to concentrations above 25 ppm can cause serious injury, including fatal pulmonary edema. Formaldehyde has low acute toxicity via the oral route. Ingestion can cause irritation of the mouth, throat, and stomach, nausea, vomiting, convulsions, and coma. An oral dose of 30 to 100 mL of 37% formalin can be fatal in humans. Formalin solutions can cause severe eye burns and loss of vision. Eye contact may lead to delayed effects that are not appreciably eased by eye washing.Formaldehyde is regulated by OSHA as a carcinogen (Standard 1910.1048) and is listed in IARC Group 2A ("probable human carcinogen"). This substance is classified as a "select carcinogen" under the criteria of the OSHA Laboratory Standard. Prolonged or repeated exposure to formaldehyde can cause dermatitis and sensitization of the skin and respiratory tract. Following skin contact, a symptom free period may occur in sensitized individuals. Subsequent exposures can then lead to itching, redness, and the formation of blisters

• Purification Methods

  It commonly contains added MeOH. Add KOH solution (1 mole KOH: 100 moles HCHO) to ~37% by weight aqueous formaldehyde solution (formalin), or evaporate to dryness, to give paraformaldehyde polymer which, after washing with water, is dried in a vacuum desiccator over P2O5 or H2SO4. Formaldehyde is regenerated by heating the paraformaldehyde to 120o under vacuum, or by decomposing it with barium peroxide. The monomer, a colourless flammable gas, is passed through a glass-wool filter cooled to -48o in a CaCl2/ice mixture to remove particles of polymer, then dried by passage over P2O5 and either condensed in a bulb immersed in liquid nitrogen or absorbed in ice-cold conductivity water. The gas or aqueous solutions have pungent suffocating odours, are LACHRYMATORY and suspected carcinogens, handle carefully. Formalin is a disinfectant and a preservative of dead animal and plant tissues. [Beilstein 1 IV 3017.]
