Figure 7. Relation between methoxy carbon proton abstraction and carbon monoxide formation from volatile anesthetics, for (A) extent and (B) rate data. Extent and initial linear rates of deuterium exchange and carbon monoxide formation are replotted from Figure 3and Figure 5. Open and closed symbols are data from potassium and sodium deuteroxide, respectively. Circles are data using barium hydroxide lime. Triangles represent soda lime. All regression were significant (P < 0.05).
