Description
Stability of the EHBA-Cr(V) complex (sodium bis[2-ethyl-2-hydroxybutanoato-(2)] oxochromate(V)) in methylamine, ethylamine, propylamine, sec-butylamine and ammonia in the presence of borane-ammonia, BH3:NH3 (0-20% w/w) has been followed spectrophotometrically between -300 to -650C. It has been observed that even a small amount of BH3:NH3 (<5% wt) can substantially retard chromium(V) disproportionation (decomposition) into chromium(VI) and chromium(III), and thus enable preparation of chromium(V) doped glasses (targets) within practical temperature (-450 to -500C) and time (30-60 min) limits.
