Properties

Formaldehyde is an important organic raw material, which is mainly used in plastic industry (such as phenolic resin, urea formaldehyde plastic electric jade), synthetic fiber (such as synthetic vinylon polyvinyl formal), leather industry, medicine, dyes, etc. Formalin has the ability of sterilization and antisepsis. It can soak biological samples. Its dilute solution (0.1-0.5%) can be used to soak seeds and disinfect seeds in agriculture. Catalytic oxidation is commonly used in industry to produce formaldehyde from methanol. Formaldehyde can react with silver ammonia solution to produce silver mirror, so that a thin layer of metallic silver as bright as a mirror is attached to the inner wall of the test tube (combined silver is reduced and formaldehyde is oxidized); It reacts with the newly prepared copper hydroxide suspension to form red precipitated cuprous oxide.
