Process safety assessments were performed on the basis of the reaction mechanism using reaction calorimetry and gas evolution analyses. Furthermore, safety equipment was prepared to prevent the leakage of diborane gas during the reaction, and the process was successfully scaled up to the pilot plant at a 35 kg scale.doi:...
Hello everyone, I am stuck on a question (again) and would like some help, as always I have done my research and come to the point where I got stuck. The question goes as followed: A simple ketone (e.g. Propanone) is readily reduced by borohydride, e.g. NaBH4, but an ester (e....
The reaction which occurs when lamiolgenin 2 is treated with an excess of NaBH4 is unusually complex owing to an intramolecular aldolic condensation which leads to a bicyclo[3.2.0]heptane derivative 4. The mechanism of this reduction has been investigated by using NaBD4. Spectral data (IR, ...
PANI microtubes were prepared through a template-free method with salicylic acid as the dopant. HAuCl4 was used as a gold precursor. Au nanoparticles were loaded on PANI microtubes by an in situ redox reaction between PANI and HAuCl4. The morphology and structure of the as-prepared PANI/Au ...
Ag-based nanoparticles (NPs) catalysts have recently attracted increasing attention in NaBH4-assisted nitrophenol reduction, especially in 4-nitrophenol (4
surface electronic structure of the platinum–nickel catalyst, and this composite catalyst composed of crystalline platinum–nickel covered by amorphous nickel boride achieves a 27-times enhancement in mass activity relative to commercial platinum/carbon at 0.9 V for the oxygen reduction reaction ...
The Mn3O4/α- Ag2WO4(60%) catalyst exhibited an excellent photo-reduction activity comprised of 0.067 s−1 towards 4-nitrophenol (0.001 M) in only 60 s reaction time using NaBH4 (0.2 M). This was due to the successful formation of the Mn3O4/α-Ag2WO4 ...

reaction processgelatinpHCu nanoparticles were prepared by reducing Cu2+ ions with NaBH4 in alkaline solution. The effects of NaBH4 concentration and dripping rate on the formation of Cu nanoparticles were studied. The optimum conditions are found to be 0.2 mol/L Cu2+, solution with pH=12, ...
One approach is a two-step process where a strong reductant, mostly NaBH4, is used to initiate the reaction, forming small particles. These particles in a second step are enlarged with a weaker reductant (Sharma et al., 2009). Another approach involves using Tollens or modified Tollens ...
