Solutions of pure D-threose and D-erythrose, buffered with bicarbonate (0.82 moles) plus carbonate (0.18 moles), were treated with an equimolar amount of C14-labeled KCN. The aldonic acids were isolated as salts, using carrier technique, in yields of 90–95% based on the radioactive carbon. D-Erythrose gave 1.89 times as much arabonic as ribonic acid while D-threose gave 2.36 times as much lyxonic as xylonic acid. Despite the unfavorable ratio in the latter case it was found that D-xylose could be obtained in an over-all yield of 22%, based on the cyanide.
