Simpsons 3/8 rule in batch distillation

Webb5 mars 2024 · Distillation of mixtures may or may not produce relatively pure samples. As distillation involves boiling a solution and condensing its vapors, the composition of the distillate is identical to the composition of the vapors.

So effectively you always need an ODD number of nodes for Simpson's rule, and therefore an even number of intervals. It is usually best to think of these things in terms of panels. The Simpson's rule panel has 3 nodes in it, so it requires 2*N+1 nodes for N panels.
