Re: The Imsides method
Hi Tony,
It is unlikely that anyone, including the Author of this procedure, has performed any MEANINGFUL COMPARISON TESTING to see what difference, if any, there is between this procedure and the standard single stage base procedure.
My testing was just to show that the procedure was not foolproof.
The claim that the procedure is foolproof has been shown to not be true and the claim that it can be performed at room temperature is meaningless because, as I have also demonstrated, the standard single stage procedure will also make biodiesel at a reduced temperature as long as everything remains liquid.
University testing I have read shows that using NaOH gives a better yield than using KOH. I am sure this is because of the water bound in the KOH most people use.
Real life experience on the several forums I am a member of has never shown a noticeable difference in yield when using KOH instead of NaOH so I suspect the difference is small.
The Advantage that this procedure might have, but no-one has shown to be the case, is that if this procedure really removes the water from the methoxide then it will not only remove the water made producing methoxide but also remove the water that was bound with KOH. This should result in a better yield- as long as the WVO being reacted is low titration.
At this point, someone needs to do some ACTUAL COMPARISON TESTING to show whether there is an advantage, and not just sitting back in a chair making wild guesses about what might be happening.
As the Chemist Neutral used to say,
"While it is good to know what should happen, it is even better to do some experiments and see what really happens"
