Formaldehyde

Formaldehyde (HCHO), also known as methanal or formalin:

1. Product Introduction: Formaldehyde has the chemical formula HCHO or CH₂O, with a molecular weight of 30.03. It is a colorless gas with a pungent odor that irritates the eyes and nose. The relative density of the gas is 1.067 (air = 1), and the liquid density is 0.815 g/cm³ (-20℃). It is easily soluble in water and ethanol. The highest concentration of formaldehyde in water can reach 55%, commonly around 40%, referred to as formaldehyde solution or formalin. It is a colorless liquid with a pungent odor.

Formaldehyde has strong reducing properties, especially in alkaline solutions. It is flammable and forms explosive mixtures with air as vapor, with explosive limits of 7%-73% (volume). The ignition temperature is approximately 300°C.
