    Uses and synthesis of Formaldehyde powder

    Formaldehyde powder is the simplest structure of aldehydes molecules, its chemical properties are active, with a certain degree of toxicity. At room temperature it is a colorless gas with a pungent odor, which can easily polymerize to form Formaldehyde CAS 50-00-0.

    Formaldehyde Raw Materials is soluble in water, alcohol and other organic solvents. The main sources of Formaldehyde powder in the environment are the combustion of fuels, industrial applications, decoration materials and various consumer products. Properties Colorless flammable gas with strong irritating and suffocating odor, irritating to human eyes and nose.

    Applications / Functions of Formaldehyde powder

    1. Formaldehyde powder is used as organic chemical material, used in medicine, synthetic fiber, synthetic resin, plastic preservative, reducing agent and so on.
    2. Aqueous solution is disinfectant and antiseptic; fumigant. It has strong bactericidal effect, and it is effective for spores and viruses. With 2% formalin can be used for instruments, gloves disinfection (immersion 1 ~ 2h), indoor with 1 ~ 2ml/m3 formalin plus a small amount of potassium permanganate crystals can be generated Formaldehyde CAS 50-00-0 vapor disinfection.
    3. Formaldehyde Raw Materials mainly used in the preparation of phenolic, urea-formaldehyde, melamine and paraformaldehyde resin, also used in the preparation of MDI, pentaerythritol, urotropin and butanediol, etc.
    4. Formaldehyde CAS 50-00-0 Used for chromatographic analysis, sterilization agent, also used for the preparation of phenolic resins and biological specimen immersion
    5. Formaldehyde powder is used for tanning fur, fixing casein finishing agent, raw material leather warehouse disinfection. It should be stored in ventilated and dry warehouse, the container should be sealed, should not be too cold or too hot, 25 ℃ is appropriate, to prevent sunlight exposure, should not be long. Protective gears such as masks, glasses and gloves should be worn when using.
    6. Formaldehyde Raw Materials is used as green feed additive.

    Formaldehyde CAS 50-00-0

    Physicochemical Property of Formaldehyde powder

    Properties Colorless flammable gas, Formaldehyde powder has strong irritating and suffocating odor, irritating to human eyes and nose.

    Production methodprocess of Formaldehyde powder

    • 1.Methanol oxidation method methanol, air and water at 600-700 ℃ through pumice silver catalyst or other solid catalysts, such as copper, vanadium pentoxide, etc. (silver and copper method is dominant), directly oxidized to generate Formaldehyde Raw Materials, absorbed with water into formaldehyde liquid. Yield to methanol as 85% -90%.
    • 2. Natural gas direct oxidation of raw materials natural gas (or coal mine gas) mixed with air, at 600-680 ℃ in the iron, molybdenum and other oxides under the action of the catalyst, a one-step oxidation of Formaldehyde CAS 50-00-0. Absorbed with water to get about 30% of the formaldehyde liquid products.
    • 3. Methylal oxidation method, the preparation process includes synthesis of methylal, methylal oxidation and absorption and treatment of high concentration of formaldehyde.
    • 4. Dimethyl ether oxidation method adopts the synthesis of syngas high-pressure synthesis of methanol by-products of dimethyl ether as raw materials, metal oxides as a catalyst to oxidize into Formaldehyde CAS 50-00-0.
    • 5. Methanol dehydrogenation method can get anhydrous formaldehyde by direct dehydrogenation of methanol, and at the same time, by-production of hydrogen. This process is a very attractive method for formaldehyde preparation. The key to its progress lies in the improvement of process catalyst performance.

    Formaldehyde powder is usually produced industrially by methanol-catalyzed oxidation. the catalyst is mainly silver, but can also be iron-molybdenum oxides. Under silver catalysis, methanol is oxidized and dehydrogenated at atmospheric pressure and 600-720°C to produce Formaldehyde powder.

    Air is sprayed into the preheated methanol, and the mixture is mixed with water vapor and passed through a superheater into a reactor equipped with a silver catalyst. The reacted gas is rapidly cooled by heat exchange in a waste heat boiler. The cooled gas enters the absorption tower to be absorbed by countercurrent with water, and the aqueous solution of formaldehyde obtained by distillation is sent to an anion exchanger to remove formic acid, and Formaldehyde Raw Materials is obtained.

    Formaldehyde Raw Materials

    Formaldehyde CAS 50-00-0 is generated by the direct oxidation of methanol, air and water at 600-700℃ through silver, copper and other solid catalysts, and absorbed with water into formaldehyde liquid.
