The solution gives up formaldehyde vapors readily. These vapors are flammable over a wide vapor-air concentration range. Water soluble. Toxic vapors such as carbon dioxide and carbon monoxide are generated during combustion. Explosion hazard: when aqueous formaldehyde solutions are heated above their flash points, a potential for explosion hazard exists.

It is produced principally by the vapour-phase oxidation of methanol and is commonly sold as formalina 37 percent aqueous solution. Formalin may be dehydrated to trioxane, a crystalline trimer, or to an amorphous polymerparaformaldehyde, which is a convenient source of gaseous formaldehyde.

Formaldehyde and ammonia yield methenamine, or hexamethylenetetramine, which is used as a urinary antiseptic. Nitration of methenamine gives the explosive cycloniteor RDX. Formaldehyde and acetaldehyde react in the presence of calcium hydroxide to give pentaerythritol, the tetranitrate of which is the explosive PETN. Large quantities of formaldehyde are used in the manufacture of urea—formaldehyde resinphenol—formaldehyde resinand acetal resin polyoxymethylene.

The reaction of formaldehyde with proteins leads to its use in the tanning industry and in treating various vegetable proteins to render them fibrous. The reactivity with proteins is also the basis for the use of formaldehyde as a disinfectantan embalming agent, and a soil sterilant. Pure formaldehyde is a colourless, flammable gas with a strong pungent odour.

Formaldehyde is an important precursor to many other materials and chemical compounds. Inthe installed capacity for the production of formaldehyde was estimated at 8.

In view of its widespread use, toxicity, and volatility, formaldehyde poses a significant danger to human health.

Formaldehyde is more complicated than many simple carbon compounds in that it adopts several different forms. As a gas, formaldehyde is colorless and has a characteristic pungent, irritating odor. Upon condensation, the gas converts to various other forms of formaldehyde with different chemical formulas that are of more practical value. One derivative is the cyclic trimer metaformaldehyde 1,3,5-trioxane with the formula CH 2 O 3.

There is also a linear polymer called paraformaldehyde. These compounds have similar chemical properties and are often used interchangeably. When dissolved in water, formaldehyde also forms a hydrate, methanediolwith the formula H 2 C OH 2.

This compound also exists in equilibrium with various oligomers short polymersdepending on the concentration and temperature.

A small amount of stabilizersuch as methanolis usually added to suppress oxidation and polymerization. Formaldehyde is an intermediate in the oxidation or combustion of methaneas well as of other carbon compounds, e. When produced in the atmosphere by the action of sunlight and oxygen on atmospheric methane and other hydrocarbonsit becomes part of smog.

Formaldehyde has also been detected in outer space see below. Formaldehyde and its adducts are ubiquitous in living organisms. It is formed in the metabolism of endogenous amino acids [ which?

Formaldehyde does not accumulate in the environment, because it is broken down within a few hours by sunlight or by bacteria present in soil or water. Humans metabolize formaldehyde quickly, converting it to formic acidso it does not accumulate in the body. It was the first polyatomic organic molecule detected in the interstellar medium. Because of the widespread interest in interstellar formaldehyde, it has been extensively studied, yielding new extragalactic sources. Formaldehyde was first reported in by the Russian chemist Aleksandr Butlerov —86 [28] and was conclusively identified in by August Wilhelm von Hofmann.

Formaldehyde is produced industrially by the catalytic oxidation of methanol. The most common catalysts are silver metal or a mixture of an iron and molybdenum or vanadium oxides. In the commonly used formox processmethanol and oxygen react at ca.Caution s : Rinse formaldehyde bottles with water before making them available for disposal. Strong sensitizer.

Causes irritation of skin, eyes, nose, and throat. Do not inhale vapor. Avoid contact with skin and clothing.

Warning s : Poison. Keep out of the reach of children. Causes irritation to skin, eyes, nose, and throat. Avoid prolonged or repeated contact with skin. Avoid inhaling vapor. Use with adequate ventilation. If swallowed: Give a tablespoonful of salt in a glass of warm water and repeat until vomit fluid is clear.

Give milk, or white of egg beaten with water. If inhaled: Remove to fresh air. Flush eyes and skin with plenty of water for at least 15 minutes. Call a physician. If not breathing, give artificial respiration, preferably mouth to mouth.

If breathing is difficult, give oxygen. Induce vomiting. Never administer anything by mouth to an unconscious person. The easiest way to lookup drug information, identify pills, check interactions and set up your own personal medication records.
