EC number: 271-237-7
CAS number: 68526-89-6
A complex combination of hydrocarbons produced by the distillation of products from the hydrogenation of isononanal from the hydroformylation of octene. It consists predominantly of C9-10 primary aliphatic alcohols, C10-20 dimer alcohols, C>18 acetals and esters and C>18 acid sodium salts and boils in the range of approximately 200°C to 400°C (392°F to 752°F).
According to screening criteria for bioaccumulation, a log pow above 4.5, a bioaccumulation in aquatic organisms of its components cannot be excluded, as the measured log pow of Octene, hydroformylation products, high boiling is 5.1 (determined via TOC) and 5.2 (determined via GC) for sample size 0.1 g/L.
Octene, hydroformylation products, high boiling, is a complex UVCB consisting of a multitude of (non-specific) structures with no pronounced lead structures/constituents. Therefore, radiolabelling of this UVCB is not possible due to the complex manufacturing process and the complexity of the substance itself (bottom product). Therefore, standard tests regarding the bioaccumulation in fish (OECD test guideline 305), which are designed for testing single substances, are not feasible for this UVCB as defined relevant constituents are not known and thus cannot be subject to radiolabelling by specific synthesis. For the same reason, the use of (Q)SARs model is not feasible.
According to screening criteria for bioaccumulation, a log pow above 4.5, a bioaccumulation in aquatic organisms of its components cannot be excluded, as the measured log pow for Octene, hydroformylation products, high boiling is 5.1 (determined via TOC) and 5.2 (determined via GC) for sample size 0.1 g/L.
