How does KOH avoid saponifcation? As far as I knew both NaOH and KOH
are equally capable of the saponification reaction.

If you want the opinion of a chemist, i think that KOH wich i use gives
better product yields (you avoid saponification and problems in the

INORGANIC Both KOH and NaOH are strong bases, meaning they ionize
completely in water to metal cations and hydroxide anions. Hence the
K-OH or Na-OH bond is ionic. In a sense you may say that one is more
polar on the basis of the fact that Potassium is more electropositive
than Sodium

Let me take a shot at this, even though inorganic chemistry is not my
forte.

KOH is more expensive so people tend to go cheaper. I think both are
exothermic.

KOH dissolves much more readily, exothermically in fact. If you assume

There is a very impressive commercial processor being manufactured in Sweden
(www.carryon.se). Looking through their specifications I noticed that they
mix Kaliumhydroxide KOH instead of Natriumhydroxide NaOH with methanol to
make their methoxide.
I asked them why and if I understood their
that the NaOH and KOH you are using are 100% each (which they are not)
the ratio of KOH to NaOH varies by their formula weight KOH is 56 that
of NaOH is 40 therefore you would use 56/40 times as much KOH by weight.

I think your wash with KOH will be more biodegradable
as well. Put it on your garden.
