摘要： Olefins may be produced by the reductive dehydroxylation of vicinal polyols and/or their respective esters, in an aqueous reaction medium, under a hydrogen atmosphere, under suitable conditions, and in the presence of a halogen-based, preferably iodine-based, catalyst, wherein a solubility enhancing agent is employed to increase the solubility of the iodine-based catalyst in the aqueous reaction medium.

摘要： Crude alcohol streams are converted to olefins under reductive or non-reductive dehydroxylation conditions, in the presence of a halogen-based catalyst. The process includes autogenous gas pressure or a gas pressure from 1 psig (~6.89 KPa) to 2000 psig (~13.79 MPa), a temperature from 50 °C to 250 °C, a liquid reaction medium, and a molar ratio of alcohol to halogen from 1:10 to 100:1.

摘要： Olefins may be produced by the non-reductive dehydroxylation of vicinal polyols and/or their respective esters, in a liquid reaction medium, under a substantially non- reductive atmosphere, in the presence of a halogen-based, preferably iodine-based, catalyst. The reaction medium may be aqueous, non- aqueous, or a combination thereof, and may in some embodiments include a solubility enhancing agent.

摘要： Olefins are produced by the reductive dehydroxylation of vicinal polyols or esters thereof, or a combination thereof, in a liquid reaction medium, under a hydrogen atmosphere, at a temperature from 50 °C to 250 °C, in the presence of a halogen-based, preferably iodine-based, catalyst. Examples of the catalyst, which may be included independently or generated
in situ , are iodine (I
2 ), hydroiodic acid (HI), iodic acid (HIO
3 ), lithium iodide (LiI), and combinations thereof.
