  • Patent number: 11597689
    Abstract: A process and system for the conversion of a feedstock comprising C3-C5 light alkanes to a C5+ hydrocarbon product, for example, a BTX-rich hydrocarbon product, by performing the alkane activation (first-stage) and the oligomerization/aromatization (second-stage) in separate stages, which allows each conversion process to occur at optimal reaction conditions thus increasing the overall hydrocarbon product yield. The alkane activation or first-stage is operated at a higher temperature than the second-stage since light alkanes are much less reactive than light olefins. Since aromatization of olefins is more efficient at higher pressure, the second-stage is maintained at a higher pressure than the first-stage. Further, fixed-bed catalysts are used in each of the first-stage and the second-stage.

  • Patent number: 11597713
    Abstract: A Reflux Rinsing method for purifying crystals using solvent vapor through dynamic equilibrium recrystallization. Feed material having tetrahydrocannabinol acid (THCA) is inserted into a reaction vessel having walls, and upper portion, and a lower portion with a bottom surface. The feed material is exposed to a hydrocarbon liquid in the reaction vessel in a quantity sufficient to keep liquid present in equilibrium with gas in the reaction vessel through the recrystallization process, forming a raw extract having THCA. The walls and bottom surface of the reaction vessel are coated with raw extract. The reaction vessel is heated and then the heating is discontinued. Vapor/thin-film DER is promoted in the reaction vessel for a predetermined length of time with no solvent reflux, resulting in formation of purified crystals of THCA under pressure. The hydrocarbon solvent is reclaimed from the reaction vessel, leaving the purified crystals and impurities.

  • Patent number: 11597720
    Abstract: The present disclosure relates to bifunctional compounds, which find utility as modulators of estrogen receptor (target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end at least one of a Von Hippel-Lindau ligand, a cereblon ligand, inhibitors of apoptosis proteins ligand, mouse double-minute homolog 2 ligand, or a combination thereof, which binds to the respective E3 ubiquitin ligase, and on the other end a moiety which binds the target protein, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from aggregation or accumulation of the target protein are treated or prevented with compounds and compositions of the present disclosure.
