Is the polycondensation reaction of formaldehyde and phenol a hazardous process that is subject to strict regulation? ? ?
This should be a polymerization reaction; however, to determine whether it is one or not, it is necessary to consider the qualitative assessment in the safety pre-evaluation report. But it’s likely that it is indeed a polymerization reaction.
