TL;DR: In this article, the separation of niobium and tantalum from each other and of these from other elements by extraction chromatography, has been investigated by the radiotracer technique.
Abstract: The separation of niobium and tantalum from each other and of these from other elements by extraction chromatography, has been investigated by the radiotracer technique. Columns made of polyurethane foam pretreated with diantipyrylmethane, tri-n-butyl phosphate, and methyl isobutyl ketone were employed. The separation was carried out in HF and HF/H2SO4 media. A quantitative separation was achieved for all elements investigated.

TL;DR: The dissolution of 2,4-dinitrophenylhydrazine in an acidic solution, such as trifluoroacetic acid, was essential for its function as a reactive matrix for MALDI-MS.
Abstract: The sensitivity, range of applications, and reaction mechanism of 2-hydrazinoquinoline as a reactive matrix for matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) were examined. Using a reaction chamber (125L) equipped with a stirring fan and a window for moving the MALDI-MS plate and volatile samples in and out, the sensitivities of 2-hydrazinoquinoline to gaseous aldehydes (formaldehyde, acetaldehyde, propionaldehyde, and n-butyraldehyde) and ketones (acetone, methyl ethyl ketone, and methyl isobutyl ketone) were determined to be at least parts per million (ppm) levels. On the other hand, carboxylic acids (formic acid, acetic acid, propionic acid, and butyric acid) and esters (ethyl acetate, pentyl acetate, isoamyl acetate, and methyl salicylate) could not be detected by 2-hydrazinoquinoline in MALDI-MS. In addition to 2,4-dinitrophenylhydrazine, a common derivatization reagent for analyzing carbonyl compounds quantitatively in gas chromatography and liquid chromatography, the dissolution of 2-hydrazinoquinoline in an acidic solution, such as trifluoroacetic acid, was essential for its function as a reactive matrix for MALDI- MS.

TL;DR: A rubber composition obtained by recycling scrap material and adapted for use as raw material for manufacturing products for building, automobile accessory, and footwear industries possibly as a replacement for wood, zinc sheet, fiber cement, plastic and any other rigid or semirigid material.
Abstract: A rubber composition obtained by recycling scrap material and adapted for use as raw material for manufacturing products for building, automobile accessory, and footwear industries possibly as a replacement for wood, zinc sheet, fiber cement, plastic and any other rigid or semirigid material The composition includes from about 66% to about 77% of particles of ground tires having a size between about 18 and about 30 microns, from about 15% to about 22% of particles of ground plastic material having a size between about 18 and about 30 microns, and from about 8% to about 12% of a solution of acid with toluene or methyl isobutyl ketone The acid may be lactic acid, phosphoric acid or formic acid The percentage of acid in the solution by volume is from about 12% to about 50% and the percentages of toluene or methyl isobutyl ketone in the solution by volume is from about 50% to about 88%

TL;DR: In this article, a method for producing a slurry composition with a good dispersibility and a method to produce a resin varnish is presented. But the method is not suitable for the use of solvices.
Abstract: PROBLEM TO BE SOLVED: To provide a slurry composition with a good dispersibility, a method for producing the slurry composition, and a method for producing a resin varnish SOLUTION: The slurry composition is produced by adding a resin component and is used as a resin varnish The slurry composition further includes an organic solvent and a silica filler added to the organic solvent The organic solvent includes a first organic solvent of being a cycloalkanone and a second organic solvent different from the first organic solvent The first organic solvent is a cycloalkanone, and the second solvent is at least one selected from acetone, methyl ethyl ketone, and methyl isobutyl ketone COPYRIGHT: (C)2010,JPO&INPIT
