摘要：

Vibrational spectroscopy in the vapour phase has shown metaboric acid cyclic trimer in equilibrium with monomeric orthoboric acid and water. An approximately equal amount of boron (1:3 mole ratio) is present as (HBO2)3 and as H3BO3, at 350-degrees-C and a few atmospheres total (water and boric acid) pressure; a condensed phase of widely variable composition is also present. Proportionately very much less trimer is present at the lowest temperatures (just over 100-degrees-C for IR work).
