Sodium borohydride is being commercialized to provide hydrogen storage for portable fuel cells. Prior kinetic studies have focused on catalytic hydrolysis of dilute aqueous solutions at room temperature. This work reports on a new NMR method for studying the kinetics of non-catalyzed sodium borohydr

โฆ Synopsis
Phenylhydroxamic
acid undergoes hydrolysis in concentrated NaOH via a complex mechanism: a maximum is observed in the plot of k, versus [NaOH] which is attributed to the existence of one or more pre-equilibria influencing the rate-limiting step.
Hydroxamic acids are-known to undergo hydrolysis in acidic, neutral and alkaline media.lm4 The reactions in aqueous NaOH, hourever, have been studied mainly at either lour ionic strength or in l-3 conditions of constant ionic strength.
An outstanding feature of these studies.is the

It was previously reported (1) that desoxyribonucleic acid (DNA) prepared under mild conditions (method of Hammarsten) (2) was readily hydrolyzed by specific nuclease so that it became soluble in HC1, whereas DNA prepared with the use of hot 1.25 N NaOH (method of Leve
