Synthetic Methods for the Preparation of 1,3-Propanediol



The market for 1,3-propanediol (PDO) is currently over 100 million pounds per year and is growing rapidly. PDO is a component of industrial polyesters such as Dupont's Sorona® and CDP Natureworks® or Shell Chemical's CorterraTM. Markets for the polyester include thermoplastics, textiles, carpets, and upholstery. This paper reviews the methods for the production of 1,3-propanediol by focusing on four feedstocks: glycerol, ethylene oxide, acrolein, and glucose.
