First came the news that Groupon China's marketing director resigned even before the company got really started. A suspicious timing to leave a business in my opinion. Then came the Superbowl Groupon ad that was very politically insensitive, to say it mildly.
53 6 CONCLUSIONS ON THE SVHC PROPERTIES 6.1 PBT, vPvB assessment Not assessed for the identification of this substance as SVHC in accordance with Article 57(f). 6.2 CMR assessment Not assessed for the identification of this substance as SVHC in accordance with Article 57(f).ue to the even slower degradation of 4-nonylphenol compared to 4-NP1-2EO (DegT50 46.2 days (primary degradation) to no elimination after 703 day in anaerobic freshwater sediment-depending on linear or branched isomers), it can be assumed that the formation of 4-nonylphenol exceeds its degradation.
Comparing the conjugate bases of cyclohexanol, phenol and benzoic acid reveals some differences. In cyclohexanol, the anion formed by loss of a proton is localized on the oxygen. There is no resonance stabilization. In phenol, the anion formed by loss of a proton is delocalized. Resonance structures show the negative charge can be shared between the oxygen atom and three of the carbons in the benzene ring. In benzoic acid, the anion is also delocalized. This time the negative charge is shared between two different oxygen atoms.
