Formaldehyde is a member of the large family of chemicals called a volatile organic compound. It is present in the gaseous state at room temperature. It is known as a gas that also dissolves in water and has a strong odor. It is a naturally occurring gas and stored as an aqueous solution (formalin). Formaldehyde is the first member of series of alphabetic aldehydes and a very reactive compound. The common name of this compound comes from its relation to formic acid. It has a wide range of applications on the industrial level.
Formaldehyde breaks within hours by sunlight or bacteria present in the soil as it does not accumulate in the environment. Human bodies made formaldehyde in the body, where enzymes break it into formic acid.
Another name of formaldehyde is methanol. Dehydration method use to synthesis formaldehyde. Its formation uses the heat obtained by burning hydrogen is used for the endothermic reaction. The oxidation process of methanol used to prepare formaldehyde; (while molybdenum and iron oxide are present as catalysts).
Formaldehyde is a non-toxic gas, but excess of anything can be fatal. The long-term presence of formaldehyde in the air can be dangerous and results in skin irritation, itching, dermatitis, and asthma, and its most hazardous form is cancer.
Formaldehyde provides a wide range of applications industry. It is a common precursor to other complex compounds and produces a whole class of different resins that use formaldehyde.
Formaldehyde produces resins like urea-formaldehyde resin, polyoxymethylene plastic, phenol-formaldehyde resin, 1,4 butanediol. The textile industry uses these resins as finishers the fabric crease-resistant. Formaldehyde has a disinfectant nature in the aqueous state; that’s why people use it as a disinfectant against bacteria and fungi
It is used in numerous industrial applications like:-
… and many more.
