  • Publication number: 20220355268
    Abstract: A method of purifying gaseous mixtures, for example ternary or quaternary gaseous mixtures, using a sorbent media comprising two or more sorbent materials. The method involves obtaining a target gas from a gaseous composition comprising the target gas, a first gas and a second gas, and optionally further gases by contacting the gaseous composition with the sorbent media to remove at least some of the first gas and at least some of the second gas from the gaseous composition. The sorbent media comprises at least a first sorbent material and a second sorbent material; wherein the first sorbent material has a higher adsorption selectivity for the first gas than for the target gas; and wherein the second sorbent material has a higher adsorption selectivity for the second gas than for target gas. The method may be particularly useful for the separation of pure ethylene, methane or propylene from such gaseous mixtures.

  • Patent number: 10130708
    Abstract: 2:1 cocrystals of amino acids and Li+ salts crystallize from hot water to afford water stable cationic networks based upon tetrahedral lithium cations: bilayered square grids, a lithium zeolitic metal-organic material (LiZMOM) and several lithium diamondoid metal-organic materials (LiDMOMs). The compositions may be used as a pharmaceutical for the treatment of suicidality and other disorders that require lithium to penetrate the blood brain barrier and exert therapeutic effects in the CNS. Advantageously, the novel cocrystal forms described herein may be used to lower the oral dose required to achieve therapeutic concentrations of lithium in the brain, thus reducing the peripheral toxicity and potentially broadening the therapeutic index in comparison to conventional lithium forms.

  • Patent number: 5994365
    Abstract: Novel diazaanthracenes of formula wherein the dotted line in the central ring indicates that either the central ring is aromatically unsaturated, and in this case either R.sup.3 or H is absent from the 10-position and either R.sup.4 or H is absent from the 5-position, or the central ring is saturated and R.sup.3 and H and R.sup.4 and H are present, and the corresponding 5,10-diones, N-oxides, N-halides, N-amine, salts, dimers, Diels-Alder adducts, carbene adducts and complexes with transition metal compounds display valuable antibacterial, anticancer and antifungal properties. The compounds of formulae (I) and (II) in which R.sup.1 and R.sup.2 are both methyl groups can be obtained by subjecting 3,5-lutidine to the effect of a strong reducing agent, for example molten sodium.
