Abstract
THE alkali perborates have been regarded by some as addition compounds of hydrogen peroxide and metaborates1, and by others as true persalts not containing hydrogen peroxide as such2. Le Blanc and Zellmann3 divided them into (α) true perborates MBO3; (β) pseudo-perborates Jlf(BO2H2O2) with firmly bound hydrogen peroxide (M is a univalent metal and (α) and (β) have one atom of active oxygen per atom of boron) ; and (c) addition compounds with loosely bound hydrogen peroxide, for example, Na(BO2H2O2),2H2O2. This differentiation into pseudo- and true perborates was not confirmed by Menzel and co-workers2. Among the perborates so far investigated, there is insufficient evidence for the existence of compounds in which the amount of water present does not permit the total active oxygen (Oα) to be present as hydrogen peroxide.
