A method for manufacturing high aspect ratio silver nanowires is provided, wherein the silver solids produced comprise high aspect ratio silver nanowires and are depleted in low aspect ratio silver particles.

Method for manufacturing high aspect ratio silver nanowires

A method for manufacturing filtered high aspect ratio silver nanowires is provided, wherein a total glycol concentration is &#x3c;0.001 wt % at all times.

Hydrothermal method for manufacturing filtered silver nanowires

A process comprising contacting deionized water with one or more Strecker sulfonation reaction products of one or more halogenated alkyl ethers in the presence of sulfite, wherein the one or more Strecker sulfonation reaction products each comprise one or more inorganic salts on a dry basis and one or more surfactant components, form a filtration mixture; loading the filtration mixture into a high pressure filtration system containing a membrane having a membrane molecular weight cutoff allowing preferential passage of the inorganic salts, for example, of greater than or equal to 200 Daltons; wherein the high pressure filtration system is operated at a pressure greater than ambient pressure and is configured to cause crossflow of the filtration mixture along a surface of the membrane resulting in a permeate solution which substantially passes through the membrane and a retentate solution which substantially does not pass through the membrane; wherein the permeate comprises less than or equal to 15 weight percent surfactant component, based on the weight of the filtration mixture is provided.

Process for reducing inorganics from anionic surfactant solutions

A process for preparing a molybdenum sulfide-based catalyst comprises drying a precipitated molybdenum sulfide-based catalyst precursor, for example, a wet filter cake, such that a particulate catalyst precursor, containing from 12 to 15 percent by weight water, is formed. The particulate catalyst precursor is desirably in the form of free-flowing particles. The particulate catalyst precursor is then auto-reduced. A rotary furnace that subjects the catalyst precursor to at least two zones having distinct temperatures may be conveniently used for drying, auto-reduction, or both. The staged drying and auto-reduction steps reduce the tendency of the precursor to self-heat, which is undesirable because it reduces both the activity and selectivity of the final catalyst.

Process for synthesis of molybdenum sulfide-based catalysts

The present disclosure is directed to a single phase acetylated castor component (SP-ACC). An acetylated castor component is purified to produce the SP-ACC which contains a reduced amount of, or no, insoluble component(s) therein. The SP-ACC enhances the performance and properties of plasticizers of which it is a component.

The present disclosure is directed to an apparatus and process for producing a catalyst composition and a low-fines catalyst composition in particular. A crossflow classification device is used to separate large catalyst particles from catalyst fines. A slurry of a catalyst composition is introduced into the crossflow classification device. A classified catalyst composition is retrieved from a retentate produced as a result of subjecting the catalyst slurry to a crossflow classification process. The solids content of the pre-classified and/or post-classified catalyst slurry is determined by way of NMR spectroscopy. The solids content determination accounts for migration of wash liquid from the catalyst composition and into the slurry liquid phase. The classified catalyst composition has a low-fines content and produces a polyolefin composition with a low polymer fines content.
