  • Iodine-based catalyst for reductive dehydroxylation of vicinal polyols to olefins
    Patent number: 9505672
    Abstract: 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 (I2), hydroiodic acid (HI), iodic acid (HIO3), lithium iodide (LiI), and combinations thereof.

  • Reductive dehydroxylation of vicinal polyols to olefins using an iodine-based catalyst having enhanced solubility
    Patent number: 9499454
    Abstract: 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.

  • Dehydroxylation of crude alcohol streams using a halogen-based catalyst
    Patent number: 9487455
    Abstract: 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.

  • Non-reductive dehydroxylation of vicinal compounds to olefins using a halogen-based catalyst
    Patent number: 9469575
    Abstract: 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.
