- C07C 4/02 by cracking a single hydrocarbon or a mixture of individually defined hydrocarbons or a normally gaseous hydrocarbon fraction
- C07C 4/08 by splitting-off an aliphatic or cycloaliphatic part from the molecule
- C07C 4/22 by depolymerisation to the original monomer, e.g. dicyclopentadiene to cyclopentadiene
- C07C 4/24 by splitting polyarylsubstituted aliphatic compounds at an aliphatic-aliphatic bond, e.g. 1,4-diphenylbutane to styrene
- C07C 4/26 by splitting polyaryl compounds at a bond between uncondensed six-membered aromatic rings, e.g. biphenyl to benzene
