Abstract: Metal-organic framework materials (MOFs) are highly porous entities comprising a multidentate organic ligand coordinated to multiple metal centers, typically as a coordination polymer. Crystallization may be problematic in some instances when secondary binding sites are present in the multidentate organic ligand. Multidentate organic ligands comprising first and second binding sites bridged together with a third binding site comprising a diimine moiety may alleviate these issues, particularly when using a preformed metal cluster as a metal source to form a MOF. Such MOFs may comprise a plurality of metal centers, and a multidentate organic ligand coordinated to the plurality of metal centers to define an at least partially crystalline network structure having a plurality of internal pores, and in which the multidentate organic ligand comprises first and second binding sites bridged together with a third binding site comprising a diimine moiety. Particular MOFs may comprise N,N′-di(1H-pyrazol-4-yl)ethane-1,2-diimine as a multidentate organic ligand.

Abstract: The application relates to processes and systems that use a furfural compound for producing five-membered carbocyclic rings that are unsaturated, such as cyclopentene and cyclopentadiene. Examples methods for conversion of furfural compounds may include converting a furfural compound to at least a five-membered, saturated carbocyclic ring, and converting the five-membered, saturated carbocyclic ring in a presence of a catalyst to at least a five-membered, unsaturated carbocyclic ring.

Abstract: Processes are provided for the removal of hydrogen from a mixture. The process can be performed by contacting a mixture comprising hydrogen, oxygen, and one or more organic compounds with a synthetic zeolite to produce water or steam. The synthetic zeolite can include Si and Al and has a SiO2:Al2O3 molar ratio of greater than 4:1, an 8-membered ring zeolite having a framework type of AEI, AFT, AFX, CHA, CDO, DDR, EDI, ERI, IHW, ITE, ITW, KFI, MER, MTF, MWF, LEV, LTA, PAU, PWN, RHO, SFW or UFI, a degree of crystallinity of at least 80% as measured by ASTM D535-197, and at least 0.01 wt % of at least one catalytic metal, based on a weight of the synthetic zeolite, where the at least one catalytic metal can include Ru, Rh, Pd, Ag, Os, Ir, Pt, Au, Mo, W, Re, Co, Ni, Zn, Cr, Mn, Ce, Ga, alloys thereof, or mixtures thereof. At least 95% of the catalytic metal can be disposed within a plurality of pores of the synthetic zeolite.

Abstract: This disclosure relates to the preparation of diphenyl compounds, especially dimethylbiphenyl compounds, in which there is one methyl group on each ring, and their oxidized analogues. These compounds, and particularly alkylated biphenyl compounds and biphenylcarboxylic acids, alcohols and esters, are useful intermediates in the production of a variety of commercially valuable products, including polyesters and plasticizers for PVC and other polymer compositions.

Abstract: The present disclosure provides base stocks and or diesel fuel, and processes for producing such base stocks and or diesel fuel by polymerizing alpha-olefins and internal olefins. The present disclosure further provides polyolefin products useful as base stocks and or diesel fuel. In at least one embodiment, a process includes: i) introducing, neat or in the presence of a solvent, a feed comprising a branched C5-C30 internal olefin, with a catalyst compound comprising a group 8, 9, 10, or 11 transition metal and at least one heteroatom and ii) obtaining a C6-C100 polyolefin product having one olefin, a methylene content of from about 1 wt % to about 98 wt %, and or a methyl content of from about 1 wt % to about 75 wt %. The feed may further include a linear C4-C30 internal olefin, a C2-C30 alpha-olefin, or a mixture thereof.

Abstract: This application relates to transfer hydrogenation between light alkanes and olefins, and, more particularly, embodiments related to an integrated olefin production system and process which can produce higher carbon number olefins from corresponding alkanes. Examples methods may include reacting at least a portion of the ethylene and the at least one alkane via transfer hydrogenation to produce at least a mixed product stream comprising generated ethane from at least a portion of the ethylene, unreacted ethylene, and an olefin corresponding to the at least one alkane.

Abstract: The present disclosure provides base stocks and processes for producing such basestocks by polymerizing internal olefins. The present disclosure further provides base stocks, comprising low molecular weight polyolefin products, having one or more of improved flow, low temperature properties, and thickening efficiency. The present disclosure further provides polyolefin products useful as base stocks and or diesel fuel. In at least one embodiment, a process includes introducing a feedstream comprising C4-C30 internal-olefins with a catalyst system comprising a nickel diimine catalyst optionally in the presence of a solvent. The method includes obtaining a C6-C100 polyolefin product having one or more of a carbon fraction of epsilon-carbons of from about 0.08 to about 0.3, as determined by 13C NMR spectroscopy, based on the total carbon content of the polyolefin product.
