Endpoint:
additional physico-chemical information
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Guideline study and GLP
Qualifier:
no guideline available
GLP compliance:
yes (incl. certificate)
Endpoint investigated:
other: Stability test in Water
Results:
Via Si-NMR and HPLC investigations it could be shown that the test itm Ethanol, 2,2'-oxybis-, reaction products with 3-(triethoxysilyl)-1-propanamine is not stable in water. It immedately undergoes condensation reaction that form "-Si-O-Si" moieties with hieg polymerization degree and liberate the diethylene glycol amount, that was initially added for reaction with 3-(triethoxysilyl)-1-propanamine.
Thus analysis of the test item Ethanol, 2,2'-oxybis-, reaction products with 3-(triethoxysilyl)-1-propanamine is not possible in aqueous solution.
Conclusions:
Via Si-NMR and HPLC investigations it could be shown that the test itm Ethanol, 2,2'-oxybis-, reaction products with 3-(triethoxysilyl)-1-propanamine is not stable in water. It immedately undergoes condensation reaction that form "-Si-O-Si" moieties with hieg polymerization degree and liberate the diethylene glycol amount, that was initially added for reaction with 3-(triethoxysilyl)-1-propanamine.
Thus analysis of the test item Ethanol, 2,2'-oxybis-, reaction products with 3-(triethoxysilyl)-1-propanamine is not possible in aqueous solution.
Executive summary:
