Full titles differ between systems:
IPC:
Refining of hydrocarbon oils, in the absence of hydrogen, by extraction with selective solvents > characterised by the solvent used > Organic compounds only > Phosphorus-containing compounds
CPC:
Refining of hydrocarbon oils, in the absence of hydrogen, by extraction with selective solvents (C10G17/00, C10G19/00 take precedence) > characterised by the solvent used > Organic compounds only > Phosphorus-containing compounds
No child classifications to compare. This is a leaf node in both IPC and CPC.
