TEST FACILITY Reimer Analytical and Associates (2001e) Solubility Not determined due to hydrolytic instability METHOD OECD TG 105-Solubility in water Remarks The half life in water to complete hydrolysis is in the region of minutes (see below). It was not possible to perform the test. The notified silane is highly reactive to moisture. Exposure to water will rapidly hydrolyse the silane, generating acetic acid and isopropanol, and eventually methylsilsesquioxane TEST FACILITY Reimer Analytical and Associates, Inc (2001f) Hydrolysis as a Function of pH METHOD OECD TG 111 Hydrolysis as a Function of pH. pH T (C) T½ mins 4 25 1 (% isopropanol present 63-86%) 10 (% isopropanol present 81-101%) 19 (% isopropanol present 72-86%) 7 25 1 (% isopropanol present 53-77%) 9 25 1 (% isopropanol present 49-73%) 10 (% isopropanol present 59-82%) 19 (% isopropanol present 68-92%) Remarks This method was modified due to the rapid hydrolysis. The hydrolysis was monitored by GC and GC/MS by tracking the evolution of acetic acid or isopropanol. The hydrolysis was measured in deionised water in buffered solutions at pH 4, 7 and 10. Due to the nature of the material and the hydrolysis products care needs to be taken with these results. The results do indicate that the hydrolysis of the notified chemical will be in minutes in the pHs tested. TEST FACILITY General Electric (2001) Partition Coefficient (n-octanol/water) Not determined METHOD OECD TG 107 Partition Coefficient (n-octanol/water), Shake Flask Method. Remarks The notified chemical was hydrolytically unstable in aqueous solution; test was not performed TEST FACILITY Reimer Analytical and Associates, Inc (2001g) Not determined screening test – Remarks Not possible to perform the soil adsorption test, due to its hydrolytic instability TEST FACILITY Reimer Analytical Associates, Inc (2001h) Dissociation Constant Not determined Remarks No dissociable groups present. Particle Size Not applicable (notified chemical is a liquid) Flash Point 81oC (closed cup)
