EC number: 205-617-0 | CAS number: 144-15-0
1) The Koc was calculated to be 9204000 L/kg; LogKoc = 7.96 (MCI method estimation) and 2009000 L/kg; LogKoc = 6.3 (traditional method based on logPow), respectively. [with KOCWIN v2.00 (EPIWIN software by US-EPA)]2) Read-across data from Tributyl-O-acetylcitrate (CAS 77-90-7): LogKoc= 4.271 [HPLC method]
The prediction for soil adsorption property of tris(2-ethylhexyl) 2-(acetyloxy)propane-1,2,3-tricarboxylate was determined by the KOCWIN program (v2.00) made available by U.S. EPA. This program requires just the input of the chemical structure of the desired compound by SMILES notation. It estimates the organic-normalised sorption coefficient for soil, which is designated as KOC. The following two models are used: the Sabljic molecular connectivity (MCI) method as well as the traditional method which is based on the logPow value of the substance. The MCI method is taken more seriously into account, due to the fact that is includes improved correction factors, resulting in a KOC value of 9204000 L/kg (LogKoc = 6.3) for the chemical compound. The traditional method (based on an estimated logPow of 9.96) gives a value of 2009000 L/kg (LogKoc = 7.96).
Accordingly the substance has a high to very high sorption onto soil organic matter.
