A process for the preparation of a quaternary ammonium bisulfate which comprises the reaction of a quaternary ammonium alkylsulfate with sulfuric acid in a solvent mixture comprised of water and isopropyl alcohol, followed by the recovery of the solid quaternary ammonium bisulfate by crystallization ...
is known to exhibit higher activity toward the OER compared to metallic Ir or IrO2due to its multiple valence states15,16,17. In particular, a linear correlation was observed between the catalytic activity of IrOxand the fraction of Ir(III) species15,18. However, due to the electrochemical ...
The catalyst was dispersed in a mixed solution containing H2O and isopropyl alcohol (IPA) (1:4 v/v), and some alkaline ionomer solution (5 wt.% versus catalyst, Sustainion XA-9) by sonication for 1 h to form a 1 mg ml−1 catalyst ink. GDEs were fabricated by spraying ...
Critical Size of Crystalline ZrO 2 Nanoparticles Synthesized in Near- and Supercritical Water and Supercritical Isopropyl Alcohol Nanocrystalline ZrO(2) samples with narrow size distributions and mean particle sizes below 10 nm have been synthesized in a continuous flow reactor in nea...

1. In the in situ acidizing of a subterranean formation by decomposing a halohydrocarbon, the improvement which comprises introducing into said formation a mixture of carbon tetrachloride, water, isopropyl alcohol and ferric chloride, wherein the weight ratio of carbon tetrachloride to water to isopro...
Pervaporation (PV) separation of water–isopropanol has been attempted using the blend membranes of poly (vinyl alcohol) (PVA) with poly (styrene-co-acrylonitrile) (PSA), and poly (vinyl alcohol) (PVA) with poly (styrene-co-methyl methacrylate) (PSM). Here, we described the fabrication of ...
and cost-effective technology to eliminate pollutants, produce clean energy, and synthesize valuable compounds. Among many methods, catalysis plays a major role in reducing production costs and boosting reaction efficiency, which will significantly advance the development of human society. Sustainability, ...
Hydrogen is needed to initiate the reaction and isomerization is accompanied by hydrogenation to the saturated alcohol. Initial turnover frequencies up to 65 mol product/mol catalyst · h were observed in neutral solutions at 80 °C. The reactions were strongly influenced by the pH of the ...
The patterned ITO glass substrates (15 Ω−1,1.5 × 1.5 cm2) were cleaned by ultrasonic treatment in detergent, distilled water, acetone, and isopropyl alcohol, and then dried in an oven overnight at 70 °C. The ZnO precursor solution was prepared by dissolving 0.2 g of ...
Nitroalkanes, such as Mannitol hexanitrate,wetted with not less than 40% water,or mixture of alcohol and water,by mass, range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in ...
