| Abstract: | The polymerization degree of industrial paraformaldehyde is determined by sodium sulfite method and iodimetry, the merits and demerits of two methods are compared. The preparation method of low polymerization degree paraformaldehyde is discussed, the effect of solvent and depolymerizing agent on the preparation is investigated. |
| Keywords: | low polymerization degree paraformaldehyde sodium sulfite method iodimetry |
