Molecular Formula: CH2O Melting-Boiling Point: -15, -21 C (37% purity) Molar weight: 30,026 g / mol It is the simplest member of aldehydes. Its other name is Metanal. It is formed by hydrogen bonding to two empty bonds of the carbonyl group. It is a toxic chemical. Its boiling point is -15 ° C and its melting point is -21 ° C. Formaldehyde is usually transported or stored as a 37% aqueous solution. This solution is called formalin. Paraformaldehyde is formed when water evaporates and separates from formalin under reduced pressure. It is a polymer, it is a white solid substance with the formula HO (CH2O) xH (x is about 30). When this polymer is heated, the gas turns into formaldehyde. Therefore, gas is a suitable source for obtaining formaldehyde. While polymer products can be obtained from pure formaldehyde, synthetic resins and plastics are produced with phenol and casein.
