SUMMARY Alcoholysis of sodium borohydride offers advantages due to reduction in number of steps for recycling of sodium borohydride, elimination of freezing problems that are associated with the use of water, fast generation of hydrogen, etc. Methanol was used to liberate hydrogen from sodium borohydride. The influence of the amount of solvent, substrate concentration, temperature and catalyst on the kinetics of alcoholysis reaction in non‐stabilized sodium borohydride has been examined in the present study. The reaction was found to be first order with respect to substrate concentration and zero order with respect to solvent concentration. Effect of soluble metal salts, metal powder and metal boride as catalysts on hydrogen generation rate has also been investigated. It was found that NiCl2, Ni2B and RuCl3 were effective catalysts and hydrogen generation proceeds with high efficiency in the presence of these catalysts. Copyright © 2013 John Wiley & Sons, Ltd.

Glycerol steam reforming, a potential technology for hydrogen production in fuel-cell applications, is of great interest to researchers in recent years.

The kinetics of ruthenium (III)-catalyzed oxidative cleavage of phenylpropanolamine (2-amino-1-phenyl-propan-1-ol) (PPA) with N-bromosuccinimide (NBS) in HCl medium has been investigated at 308 K. The oxidation reaction follows the rate law, d, where a and b are less than unity. The stoichiometry of the reaction has been found to be 1:1, and benzaldehyde and acetaldehyde were identified as the oxidation products of PPA. The activation parameters have been evaluated from the Arrhenius plot. NBS itself has been postulated as the reactive oxidizing species. The observed results have been explained by plausible mechanisms and the related rate law has been deduced.
