    Description
     

    Formaldehyde: A colorless liquid, easy to polymerize, soluble in water, alcohol and ether. It could 

    be quickly oxidized to formic acid in the air, also a strong reducing agent, boiling point -19 ℃,

    freezing point -118 ℃, the relative air density 1.067.

     

     

    Commercial products are supplied in liquid form, called formalin, which is a 37 to 50%

    formaldehyde solution plus a small amount alcohol as polymerization inhibitor.

     

    The solution is milky white with foul odor. Formalin easily gasified formaldehyde

    gas, the boiling point of 96 ℃, the relative density of 0.815 / -20 ℃, the flash

    point of 55 ℃.

    Storage and Packaging

     

    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.
