| 摘 要： | 综述了环氧乙烷羰基化法、丙烯醛水合加氢法和微生物发酵法生产 1 ,3-丙二醇工艺路线的原料、催化体系、工艺过程及研发状况。比较了 3种工艺路线的工艺特征、装置投资和生产成本。指出环氧乙烷羰基化法原料易得、成本较低 ,但技术难度高、设备投资大 ;丙烯醛水合加氢法成本略高 ,但反应条件缓和、技术开发相对容易 ,且拥有丙烯醛生产技术和基础 ;微生物发酵法反应条件温和、原料价廉易得、成本低 ,但距离工业化还有一定差距。

| 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. |
