【Abstract】 The production technologies of 1,3-propanediol by hydroformylation of ethylene oxide,hydration and hydrogenation of acrolein,and corn fermentation are summarized from their material,catalyst system,process,development and production status.The technical characteristics,plant investments and production costs of above three technologies are compared.It is indicated from the introduction and comparison that there are some things worthy to be mentioned such as the abundant material and low cost,but extremely complex process and more investment needed for the technology of hydroformylation of ethylene oxide; and a little higher cost,gentle reaction conditions,relatively simple process for the technology of hydration and hydrogenation of acrolein with the integrated production technology of acrolein; and the gentle reaction condition,abundant and cheaper material,low cost for the technology of corn fermentation,it is still a long way to go for the industrialization.更多还原
