    摘要： The invention is directed to a process to continuously prepare a cyclic carbonate product by reacting an epoxide compound with carbon dioxide in the presence of a supported dimeric aluminium salen complex. The process is performed in a reactor comprising a slurry of the supported dimeric aluminium salen complex and liquid cyclic carbonate product. The produced cyclic carbonate is discharged from the reactor while the supported dimeric aluminium salen complex remains in the reactor. The liquid carbonate product is purified by means of distillation. Between the reactor and the distillation one or more buffer vessels are present having a volume of between 5 and 50 m3 per kmol of dimeric aluminium salen complex as present in the reactor.

    摘要： A method of forming polymerization auxiliaries for a polymerization process may include combining an antifouling agent with a killer agent to form an auxiliary composition; and contacting the auxiliary composition with an alkylaluminum. An antifouling complex may be produced by combining an antifouling agent with a killer agent to form an auxiliary composition; and contacting the auxiliary composition with an alkylaluminum.

    摘要： Processes of selectively depositing a metal-containing film comprise: providing a surface having a plurality of materials exposed thereon simultaneously, and exposing the surface to a vapor of a metal-containing film-forming composition that contains a precursor having the formula: LxM(—N(R)—(CR′2)n—NR″2) wherein M is a Group 12, Group 13, Group 14, Group 15, Group IV or Group V element; x+1 is the oxidation state of the M; L is an anionic ligand, independently selected from dialkylamine, alkoxy, alkylimine, bis(trialkylsilylamine), amidinate, betadiketonate, keto-imine, halide, or the like; R, R″ each are independently a C1-C10 linear, branched or cyclic alkyl, alkenyl, or trialkylsilyl group; R′ is H or a C1-C10 linear, branched or cyclic alkyl, alkenyl or trialkylsilyl group; n=1-4, wherein at least one of the materials is at least partially blocked by a blocking agent from the deposition of the metal-containing film through a vapor deposition process.

    摘要： Metal-organic frameworks (MOFs) are highly porous entities comprising a multidentate ligand coordinated to multiple metal atoms, typically as a coordination polymer. MOFs are usually produced from a solvent in powder form under hydrothermal or solvothermal synthesis conditions. Alternately, powder-form precursors of MOFs may be formed by milling or mulling a substantially solid mixture of a metal salt and a multidentate organic ligand, optionally in the presence of a small amount of a solvent. The powder-form precursors may then undergo heating, typically in the absence of applied shear, to produce the corresponding MOF. Mulling may be differentiated from milling at least in that mulling applies to the substantially solid mixture at a non-constant pressure and milling applies a constant pressure while forming the powder-form precursor. In some cases, mulling may promote more effective formation of the powder-form precursor compared to milling.
