Description of TRIOXANE

• Paraformaldehyde (PFA) is the smallest polyoxymethylene, the polymerization product of formaldehyde with a typical degree of polymerization of 8–100 units. Paraformaldehyde commonly has a slight odor of formaldehyde due to decomposition. Paraformaldehyde is a poly-acetal.

What is Paraformaldehyde ?

• With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Paraformaldehyde   which has developed particularly rapidly in recent years. Do you know about Paraformaldehyde?
• The official answer：Polyoxymethylene (POM) is a polymer of formaldehyde (high molecular weight paraformaldehyde), generally with a structural length of eight to one hundred units. Long-chain paraformaldehyde is commonly used in heat-resistant plastics, also known as polyoxymethylene (POE, DuPont’s Berlin). Paraformaldehyde decomposes rapidly, releasing slightly odorous formaldehyde.

What’s the application of Paraformaldehyde ?

• Paraformaldehyde is solid formaldehyde with high formaldehyde content, in the form of solid granules, easy to store and transport. It can be turned into formaldehyde vapor at a higher temperature, which is easy to participate in various reactions instead of high concentration of formaldehyde, which is beneficial to chemical and pharmaceutical chemical synthesis and other industrial applications, especially in the synthesis requiring the use of anhydrous formaldehyde as raw material, and is widely used. Mainly in the following areas (1) pesticides: synthesis of ethephon, butylamine, and glyphosate, etc.; (2) paint: synthesis of high-grade automotive paint; (3) resin: synthesis of urea-formaldehyde resin, phenolic resin, polyacetal resin, honey amine resin, ion exchange resin, etc. and a variety of adhesives; (4) paper: synthesis of paper enhancers; (5) casting: sanding decoiler, synthetic casting adhesives; (6) breeding industry: fumigation disinfectant. (7) Organic raw materials: used in the preparation of pentaerythritol, trimethylolpropane, glycerol, acrylic acid, methyl acrylate, methacrylic acid, N-hydroxymethacrylamide, alkylphenol, methyl vinyl ketone, etc. (8) Others: Medicine and disinfection.
