Morphology
oil + of + vitriol
The compound simply names a substance: 'oil' (an oily liquid) + 'vitriol' (sulfuric acid), so a learner who knows both constituents can infer an oily form or substance of vitriol — i.e., sulfuric acid. The 'X of Y' substance-naming pattern is common and cross-linguistically familiar, making the meaning directly derivable despite the term's archaic register.
Etymology
The noun oil of vitriol comes from old chemistry: people heated crystals that looked like glass called vitriol and made a sharp, oily liquid that could burn things. So, the name stayed and today oil of vitriol refers to the very strong liquid 'sulfuric acid' used in industry.
