China Paraformaldehyde Suppliers - High-Quality Factory Production for Industrial Applications
Appearance
Paraformaldehyde is a solid form of formaldehyde. It is often found in the form of small, granular particles or as a fine powder. It is soluble in water and commonly used as a source of formaldehyde in various applications. Paraformaldehyde can depolymerize to release formaldehyde gas when heated, making it useful for applications where a slow release of formaldehyde is required, such as in disinfection, preservation, and as a fixative in biological specimens. It is also used in the production of resins, plastics, and as a fumigant in agriculture.
Applications
The applications of paraformaldehyde include:
1. Disinfection and Sterilization:
Paraformaldehyde is used as a disinfectant and sterilizing agent in various settings, including healthcare facilities, laboratories, and industrial environments.
2. Agriculture:
It is used as a fumigant and preservative in agriculture to control pests, fungi, and bacteria in stored agricultural products and soil.
3. Production of Resins:
Paraformaldehyde is a key raw material in the production of resins, such as phenol-formaldehyde and urea-formaldehyde resins, which are used in the manufacturing of wood products, adhesives, and coatings.
4. Chemical Synthesis:
It is used as a source of formaldehyde in various chemical reactions and synthesis processes.
5. Biological Fixative:
Paraformaldehyde is used as a fixative in biological specimen preparation for microscopy and other laboratory analyses.
Packages
Packed in 25kg Hazardous chemicals packaging bags
Characteristics
Chemical Structure:
It is a polymer of formaldehyde, typically existing as a white, crystalline powder. Its structure consists of linear chains of formaldehyde molecules.
Solubility:
Paraformaldehyde is soluble in water, and upon heating or in the presence of acids or bases, it can depolymerize back into formaldehyde.
Melting Point:
It has a melting point of around 150-160°C (302-320°F), which can vary depending on the degree of polymerization.
Reactivity:
Paraformaldehyde is reactive and can release formaldehyde gas, which is a known irritant and potential carcinogen.
Antimicrobial Properties:
It exhibits effective antimicrobial properties, making it useful as a disinfectant and preservative in laboratory and medical settings.
Frequently Asked Questions (FAQ)
What is Paraformaldehyde?
Paraformaldehyde is a solid form of formaldehyde. It typically exists as small, granular particles or a fine white crystalline powder.
What happens when Paraformaldehyde is heated?
When heated, paraformaldehyde depolymerizes to release formaldehyde gas. This slow release makes it highly effective for disinfection, preservation, and agricultural fumigation.
What are the main applications of Paraformaldehyde?
Its primary applications include disinfection and sterilization, agricultural preservation, the production of resins (like phenol-formaldehyde), chemical synthesis, and as a biological fixative in laboratories.
How is this chemical typically packaged?
Paraformaldehyde is securely packed in 25kg Hazardous chemicals packaging bags to ensure safe transport and handling.
What is the melting point of Paraformaldehyde?
It has a melting point ranging between 150-160°C (302-320°F). The exact melting point can vary slightly depending on its degree of polymerization.
Is Paraformaldehyde soluble in water?
Yes, it is soluble in water. In the presence of water, heat, acids, or bases, it can easily depolymerize back into liquid or gaseous formaldehyde.
