trimerization of aldehydes
Molecular formula :

nature : the three elements of polymerized into the three aldehyde polymer reaction. For example : Formaldehyde can aggregate into three POM, acetaldehyde can aggregate into three METALDEHYDE. Ring of three POM and three METALDEHYDE, equivalent to the Central ether structure, relatively stable, and therefore often use three forms polymer preservation of formaldehyde and acetaldehyde. When used in the three polymer adding a small amount of sulfuric acid reheating, depolymerization formation of aldehydes steamed, balance depolymerization move last three polymer all depolymerization to aldehydes.
