Abstract: The present disclosure relates to a method of separating a compound of interest, particularly unsaturated compound(s) of interest, from a mixture. The compound is separated using a column having a chromatographic stationary phase material for various different modes of chromatography containing a first substituent and a second substituent. The first substituent minimizes compound retention variation over time under chromatographic conditions. The second substituent chromatographically and selectively retains the compound by incorporating one or more aromatic, polyaromatic, heterocyclic aromatic, or polyheterocyclic aromatic hydrocarbon groups, each group being optionally substituted with an aliphatic group. In some examples, the present disclosure can include a chromatographic system having a chromatographic column having a stationary phase with a chromatographic substrate containing silica, metal oxide, an inorganic-organic hybrid material, a group of block copolymers, or a combination thereof.

Abstract: This invention generally relates to a process for manufacturing a lithium selective adsorbent and, more particularly, to a process for manufacturing a lithium selective adsorbent using a recycled and augmented intercalation reaction liquor. An initial quantity of adsorbent precursor is intercalated with lithium using an intercalation reaction liquor to produce an intercalated layered aluminate adsorbent and a post-intercalation reaction liquor. The post-intercalation reaction liquor is decanted, and the intercalated layered aluminate adsorbent is neutralized to produce the lithium selective adsorbent. The decanted intercalation reaction liquor is reconstituted to a pre-intercalation reaction volume of the intercalation reaction liquor, which is recycled to intercalate a subsequent quantity of adsorbent precursor.
