A novel integrated process of extraction with ionic liquid (IL) and reductive desulfurization by sodium borohydride (NaBH4) was presented for gasoline desulfurization. The factors that influenced desulfurization efficiency were investigated and desulfurization efficiency reached more than 97% for model gasoline and more than 93% for real gasoline.

Abstract Classical process for dyeing by indigo uses generally the sodium dithionite as reducing agent. In this paper, a new technique of reduction of indigo by sodium borohydride in the presence of a catalyst and without the addition of alkali was developed. This reduction was carried out at a temperature range of 40–70 °C. In order to determine the

Solution-processed transparent conductive oxides offer the advantages of low-cost, high-throughput fabrication of electronic devices compared to the specific requirements of vacuum deposition techniques. However, adapting the current state of the art to ink deposition calls for optimization of the precursor ink composition and the postdeposition ...

Preparation and properties obtained by borohydride reduction process magnetic powders (abstract)
Journal of Applied Physics, 1988An overview on the variation of the magnetic properties, the grain size, the structure, and the heat of crystallization in the amorphous-crystalline state transition of single-domain metal particles depending on the element metals, boron, and the hydrogen contents is presented.

Abstract The mechanism of the chemical borohydride reduction process and the hydrodynamic conditions in the solutions predetermine the contents of bounded boron and hydrogen atoms. The influence of the technological conditions and the equipment used on the compositions, on the structures — amorphous or nanocrystalline — and on the magnetic properties

The reduction of aryl trifluoromethyl ketones by sodium borohydride. The hydride transfer process
Canadian Journal of Chemistry, 1980The rates of reduction of 17 aryl trifluoromethyl ketones by sodium borohydride in 2-propanol have been measured. The rho (ρ) value is +3.12, excluding the 4-amino and 4-dimethylamino groups, which both lower the rate to a greater extent than their σ values predict.

The crystallization process of a−Fe35Ni15B26 ultrafine alloy particles prepared by chemical reduction with borohydride was investigated mainly by Mossbauer spectroscopy. The experimental results exhibit some new characteristics which were attributed to the microstructure of the sample.
