in the presence of hydrogen-generating compounds

Introduced: January 1980

Full Title

Full titles differ between systems:

IPC:

Cracking of hydrocarbon oils, in the presence of hydrogen or hydrogen-generating compounds, to obtain lower boiling fractions > in the presence of hydrogen-generating compounds

CPC:

Cracking of hydrocarbon oils, in the presence of hydrogen or hydrogen- generating compounds, to obtain lower boiling fractions (C10G15/00 takes precedence; destructive hydrogenation of non-melting solid carbonaceous or similar materials C10G1/06) > in the presence of hydrogen-generating compounds

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.

IPC defines codes here since 1980.
