| titleOfInvention | Hydrogenation of isohexide products for improved color |
| abstract | Dehydrating at least one hexitol using an acid catalyst to form a crude dehydration product mixture comprising at least one isohexide; Further processing said mixture to separate at least one fraction of at least one higher purity or higher concentration of isohexides; And a hydrogenation catalyst in the presence of a hydrogenation catalyst to produce a crude dehydration product mixture, b) a neutralized crude dehydration product mixture after neutralization of the crude dehydration product mixture; c) a product mixture after the neutralization step and after an additional step to remove ionic species from the crude dehydration product mixture; d) higher purity or higher concentrations of oil; And e) hydrogenating at least one of the lower purity or concentration of the oil fraction. Hydrogenation improves the color and / or color stability of these materials, particularly the final isohexad product. |
