Formaldehyde
Formaldehyde: It is a colorless liquid, easily polymerized and soluble in water, alcohol and ether. It can be rapidly oxidized to formic acid in the air, and it is a strong reducing agent with a boiling point of -19°C, a freezing point of -118°C, and a relative air density of 1.067. The commercial product is supplied in liquid form, called formalin, which is a 37-50% formaldehyde solution with a small amount of methanol as a polymerization inhibitor. The solution is milky white with foul odor. Formalin is easily vaporized to release formaldehyde gas, the boiling point is 96°C, the relative density is 0.815/-20°C, and the flash point is 55°C.

Formaldehyde

 

Usage/Application:
  Formaldehyde is an aqueous solution with a mass concentration of 37-55%. It is a basic chemical raw material and has a wide range of prospects. Generally prepared from methanol by air oxidation. About one third of the methanol produced in the world for the production of formaldehyde is formaldehyde . 37% of the total output of formaldehyde in the world was 19.2 million tons in 1996; Hundreds of formaldehyde downstream products have been developed in various countries in the world, but there are only about 10 kinds of formaldehyde in our country at present. The main downstream products of formaldehyde thermosetting resin - urea-formaldehyde resin, phenolic resin and melamine formaldehyde resin and polyoxymethylene, pentaerythritol, urotropin, methylal, 1,4-butanediol, pyridine, ethylene glycol, Hydroxy methane and other chemical products. At the same time in agriculture, medicine, dye industry formaldehyde can be used as pesticides and reducing agents etc.
