Morphology

rectification = rectify (semi-transparent) = rectify + ation

The chemical meaning ('purify by distillation') is a specialized sense of 'rectify', so the morphological relation to the verb is clear but domain-specific.

Etymology

Rectification comes from the Latin root rectus, meaning 'straight' or 'right', and the same idea appears in the verb rectify. In chemistry, rectification is the repeated distillation that makes a liquid pure, so you can remember it as making the substance 'right' or pure by removing wrong parts.
