Propanediol (a.k.a. PDO, Trimethylene Glycol, 1,3-Propanediol, Bio-Propanediol) is a three-carbon diol compound, applied as a building clock in the production of polymers, such as polytrimethylene terephthalate (PTT). It appears as a colorless to pale yellow viscous liquid, soluble in water, ethanol and ether. Propanediol is usually produced by hydration of acrolein, or via hydroformylation of ethylene oxide and subsequent hydrogenation of the intermediate 3-hydroxypropionaldehyde. It may also be produced by microorganisms using renewable sources, such as corn syrup and glycerol, as feedstock. In such cases, it may be referred to as Bio-Propanediol or Green Propanediol.
Intratec offers professional, easy-to-understand reports examining Propanediol production. Each study describes an industrial plant, including main process units and site infrastructure, and presents an independent analysis of capital and operating costs. All reports are based on the most recent economic data available (2019/20).
