Solid Paraformaldehyde PFA,
Paraformaldehyde PFA Industrial Grade
Paraformaldehyde PFA ±96% 25kg/Bag (CH2O)N Para Formaldehyde Industrial Grade
Paraformaldehyde is a white flammable crystalline powder with formaldehyde odor. Dissolves slowly in cold water, dissolves faster in hot water. The solubility of water at 20℃ is 0.24g/100cm3H2O. Insoluble in ethanol, ether. Soluble in caustic soda and potassium solution.
Polyformaldehyde is a solid formaldehyde with high formaldehyde content. It is a solid particle, which is convenient for storage and transportation. At a higher temperature can become formaldehyde vapor, easy to replace the high concentration of formaldehyde ginseng Chemicalbook and a variety of reactions, is conducive to chemical, pharmaceutical and other chemical synthesis and other industrial applications, especially in the use of anhydrous formaldehyde as raw material synthesis, widely used.
