WebOn the other hand, the maximum biodiesel yield was achieved to be 97.335% utilizing KOH of 0.4 wt% and methanol of 20.39 wt%, at the reaction temperature of 57.1 °C, and reaction time of 54.1 min.
WebSep 5, 2007 · In both cases the reaction is hydroxide ions + glass gives silicate ions. The K and Na don't enter into the reaction. One possible reason is that a 10% solution of NaOH has more OH in it than a 10% solution of KOH because the K weighs more than the Na. If both the solutions were the same molarity then I'd expect very similar reaction rates.
