Abstract
This disclosure relates to a method for producing a class of quaternary ammonium borate compounds, and more particularly, to an improved method for producing quaternary ammonium borates by adding a glycol to the boric acid that provided the compound's anion so as to form a borate ester chelate complex having a rate-enhancing effect.
