Abstract
Processes of producing 1,4-dioxan-2-one (p-dioxanone) are improved by the addition of a blocking agent to a crude reaction product containing p-dioxanone. The blocking agent reacts with unreacted starting materials in the crude reaction product to protect the active sites thereon with groups that do not initiate polymerization of p-dioxanone. The polymerization of p-dioxanone before its recovery from the process is thereby inhibited.
