China Paraformaldehyde Suppliers - High-Quality Factory Production for Industrial Use and Laboratory 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
Q1: What is the physical form and appearance of paraformaldehyde?
Paraformaldehyde is a solid form and polymer of formaldehyde that typically exists as a white crystalline powder or in the form of small, granular particles.
