Paraformaldehyde is a polymer obtained from the polycondensation of formaldehyde molecules in an aqueous solution. It is formed by a mixture of polyoxymethylenglycols containing 87-98% of formaldehyde, being the balance up to 100% mainly combined water and small amounts of methanol.
The paraformaldehyde produced by Ercros is 89%-98% pure, allowing high concentrations of formaldehyde to be used in a solid state, with none of the inconveniences involved in handling the aqueous solution. This increases the capacity of the reactors and diminishes or does away with the need to eliminate water by distillation. This leads to big energy savings, and reduces or eliminates liquid effluent.
