Abstract

A process to convert glycerin into propylene glycol and purifying the produced propylene glycol is described. The glycerin-based propylene glycol production requires only one process step compared to petroleum/natural gas-based propylene glycol production requires multiple process steps, and thus represents a cost savings.
