Paraformaldehyde is a very important chemical raw material. The synthesis technology of trioxane has been monopolized by Europe, America and Japan. The main process is sulfuric acid catalysis. High-purity trioxane is an important monomer for polyacetal resin. The purity quality of paraformaldehyde directly affects the quality of polyoxymethylene products. Therefore, the production process of paraformaldehyde has been widely recognized in industrial production.
Paraformaldehyde is a cyclic trimer of formaldehyde. It is a very stable crystal. It is used as an intermediate in engineering plastics polyoxymethylene and other chemicals, as a disinfectant, etc. It can also be used to make epoxy resin and bisphenol A. Catalyst is the main raw material for daily use cosmetics cold decontamination and depilatory agent. It can also be used to synthesize transparent plastic and isocarbyl thioglycolate, the basic raw material of thermal stabilizers such as organic antimony and organotin. The reagent products are iron, molybdenum and silver. Sensitive reagent for metal ions such as tin. Paraformaldehyde is an important organic chemical raw material. It can also be used as an inhibitor of copper sulfide and iron sulfide minerals in mineral processing.
