Gas Chromatographic Estimation of Carbon Monoxide Produced During Oxygen Absorption by Alkaline Pyrogallol

摘要

Oxygen absorption by alkaline pyrogallol caused the formation of about 0.001 ml of carbon monoxide for each ml of oxygen absorbed. Larger amounts of CO were produced when the oxygen absorption capacity of the pyrogallol was nearly expended by absorption of more than 20 ml of oxygen per ml of pyrogallol. No carbon monoxide was produced when oxygen was absorbed with Fieser's solution. The use of Fieser's solution is recommended for oxygen absorption when minimal amounts of carbon monoxide are required in the residual gas. (Author)
