Paraformaldehyde PFA Specification

Paraformaldehyde PFA Specification

Paraformaldehyde PFA specification

Paraformaldehyde is a white, solid polymer of formaldehyde with the pungent, characteristic formaldehyde odor. Paraformaldehyde is created up of connected formaldehyde molecules. Paraformaldehyde is slightly soluble in alcohols and insoluble in ethers, hydrocarbons, and carbon tetrachloride. It is relative insoluble in cold water, but soluble in very hot drinking water with depolymerization. The solubility and fee of remedy of paraformaldehyde in h2o are tremendously affected by pH and temperature.
