不一定是这样的,根据加拿大环保署的说法,DHNUP是由六个物质组成。这六个物质的CAS号分别为:85507-79-5,68515-44-6,68515-45-7,111381-89-6,111381-90-9,111381-91-0.
我查到的6种物质的CAS号和你列的略有不同![]()
文中还提到:It should be noted that these components, except for CAS RN 3648-20-2, are themselves mixtures of branched and linear compounds.
所以,其实后面这5种CAS号都是直连和支链的混合物的。
在DHNUP的Supporting documentation 中有这样一段注释:
* According to [Environment Canada 2009] the physico-chemical properties are based on a test chemical named Palatinol
® 711P, a trade name representing the following six CAS Numbers: 85507-79-5, 68515-44-6, 68515-45-7, 111381-89-6, 111381-90-9 and 111381-91-0. It is notable that one of the components of DHNUP, diundecyl phthalate, (CAS No. 3648-20-2), is replaced by diundecyl phthalate, branched and linear (CAS No. 85507-79-5), in Palatinol® 711P. The IUCLID dataset, however, does not mention Palatinol® 711P in this context, and gives the impression that test results is based on experiments with DHNUP (CAS No 68515-42-4). [Environment Canada 2009] has in their assessment considered Palatinol® 711P to be equivalent to DHNUP
