| dcterms_is_replaced_by | 1 | pipeline.collision_decisions | merged onto 08a91e70-3ddc-11dd-933e-0050c2490048 by curator ruling: Unspecified air. Six factors each side. EF 3.1 publishes hexafluoroethane twice in each of four air compartments, once as `HFC-116` and once as `PFC-116`, both carrying CAS 76-16-4 and the same characterisation. `HFC-116` is wrong as chemistry -- hexafluoroethane is C2F6 and contains no hydrogen at all, so it is not a hydrofluorocarbon -- and it is nonetheless the copy that carries everything else: EC 200-939-8, twelve synonyms, EF's own general comment, and the rows ecoinvent 3.8 and 3.12 both map onto. The `PFC-116` copy carries the registry number and one synonym, and no list reaches it. So the survivor is the identified row in all four, and in one of the four that is the opposite of what a sort would do: the factor counts tie, the tiebreak falls through to the identifier, and in rural medium stack it picks the bare `PFC-116` row. Which of the two names is the correct designation does not decide anything here, because neither is published: Common Chemistry and ChEBI agree on `Hexafluoroethane` and the rename has already happened. Both part numbers survive as alternative labels (#530). |
