Depolymerization of chloroaldehyde cyclic trimers

摘要

A method for producing high purity chloroaldehyde monomers at a high yield by depolymerization of a chloroaldehyde cyclic trimer represented by the following formula, <IMAGE> wherein R is a hydrogen atom, methyl group, or an ethyl group. The depolymerization reaction can be carried out in the presence of activated clay. Said chloroaldehyde cyclic trimer can be stored in a stable manner and chloroaldehyde monomers obtained by the depolymerization can be used as are as a raw material for the synthetic reaction of chloroaldehyde derivatives.
