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: The present invention provides an acidic gas adsorbent having improved heat resistance. The acidic gas adsorbent of the present invention includes a porous body, and an amine compound being a solid and being supported on surfaces of pores of the porous body. The acidic gas adsorbent includes, for example, a cover layer covering the surfaces of the pores of the porous body, and the cover layer includes the amine compound. As an example, when each pore of the porous body is assumed to have a spherical shape, the cover layer has a thickness of 5.0 nm or less, the thickness being calculated from the average pore diameter of the porous body, the pore volume of the porous body, and the pore volume of the acidic gas adsorbent.

Abstract: A stationary phase for high-performance liquid chromatography including monofunctional primary silane functionalized silica provides improved separation performance for the preparative or process scale purification of cannabidiol (CBD) and tetrahydro-cannabinol (THC). Silica bonded with monofunctional primary silane(s) provides more efficient separation of these molecules through higher resolution values, reduced peak broadening and lower separation impedance, thus enabling higher purity product or more efficient purification process.

Abstract: A process for removing hydrogen sulfide (H2S) from a H2S-containing gas composition includes charging a liquid to a reactor under continuous agitation and dispersing particles of a zinc-based zeolitic imidazolate framework-8 (ZIF-8) in the liquid to form a ZIF-8 mixture. The method further includes introducing the H2S-containing gas composition to the reactor containing the ZIF-8 mixture under continuous agitation and passing the H2S-containing gas composition through the ZIF-8 mixture. In addition, the method includes adsorbing the H2S from the H2S-containing gas composition onto the ZIF-8 to remove the H2S from the H2S-containing gas composition and form a purified gas composition.
