Sodium Borohydride in Vat Dyeing
Textile Research Journal, 1970A suitable redox titration procedure has been standardized and the effect of sodium borohydride in various vat dyebaths has been studied. An analysis of the redox curve gives valuable data on the stability of the reducing system, leucopotential of the dye, and over-all stability of the dyebaths. It is shown that sodium borohydride does not improve the

Chemoselective reductions with sodium borohydride
Canadian Journal of Chemistry, 1989Under the appropriate reaction conditions, sodium borohydride is a highly chemoselective reducing agent. The order of reactivity among carbonyl groups is conjugated enones < ketones < conjugated aldehydes < aldehydes. In general, a carbonyl group of one type can be selectively reduced in the presence of a carbonyl group of a less reactive ...

Analytical monitoring of sodium borohydride
Analytical Methods, 2013Sodium borohydride (NaBH4) determination, both qualitative and quantitative, is of great significance in a plethora of areas. These include NaBH4 for energy systems such as direct borohydride fuel cells and in hydrogen production and storage, as well as use as a reducing agent in organic and inorganic synthesis reactions or in electrodeposition ...

Hydrogen cycle with sodium borohydride
International Journal of Hydrogen Energy, 2008Abstract In this paper, we review production of NaBH 4 as hydrogen storage material. Linking this with other processes, we create a system to recycle hydrogen. Difficulties and advantages of NaBH 4 synthesis by natural available boron source colemanite and borax minerals were discussed. We show that basic chemicals suffice for NaBH 4 production in

Chloride substitution in sodium borohydride
Journal of Solid State Chemistry, 2011Abstract The dissolution of sodium chloride and sodium borohydride into each other resulting in formation of solid solutions of composition Na(BH 4 ) 1− x Cl x is studied. The dissolution reaction is facilitated by two methods: ball milling or combination of ball milling and annealing at 300 °C for three days of NaBH 4 –NaCl samples in molar ...

Hydrogen Generation Via Sodium Borohydride
AIP Conference Proceedings, 2003Along with the technological challenges associated with developing fuel cells and hydrogen burning engines, a major issue that must be addressed to ensure the ultimate success of a hydrogen economy is the ability to store and transport hydrogen effectively.

Sodium borohydride reduction of anthocyanidins
Phytochemistry, 1972Abstract The reduction of anthocyanidins with NaBH 4 in EtOH or MeOH produces inter alia racemates of epicatechins. Thus, the (±) racemates of 3′,5′-di- O -methylepigallocatechin, 3′- O -methylepigallocatechin, and 3′- O -methylepicatechin have been identified as the reduction products of malvidin, petunidin, and peonidin, respectively, by their ...
