WATER SOLUBILITY (BY ANALYSIS OF TOC) TEST SUBSTANCE Identity: Perfluorooctanesulfonyl fluoride; may also be referred to as POSF, or FX-8. (1-Octanesulfonyl fluoride, 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecafluoro-, CAS #30735-7). Remarks field: The test substance is a clear liquid of uncharacterized purity. METHOD Method: Solubility screening procedure developed by 3M Company GLP (Y/N): No Year (study performed): 1984 Sample preparation: FX-8 was added to water in three different glass containers to obtain nominal concentrations of 10, 30, and 100 mg/L. The containers were sealed, and mixed for > 6 hours. After mixing, the containers were allowed to settle overnight. Sampling: Samples taken from just below the surface of each bottle and completely filled sample vials. TOC analyses: TOC measured within 24 hours of sampling, and again on samples taken 1-2 weeks after the mixing containers were prepared. The 1-2 weeks samples were stored at room temperature. RESULTS Values using the TOC analyzer within 24-hours of sampling: Sample 1 (nominal 10 mg/L): < 2 mg/L TOC Sample 2 (nominal 30 mg/L): < 2 mg/L TOC Sample 3 (nominal 100 mg/L): < 2 mg/L TOC Values for TOC 1-2 weeks after preparation: Not available. Remarks: This study was only a screen for solubility. Description of solubility (e.g., miscible to soluble to not soluble): Slightly soluble. DATA QUALITY Reliability: Klimisch ranking = 3. This study does not meet criteria for quality testing. Actual concentrations were not measured. The value was determined by indirect measurement. Additionally, this study lacks sufficient characterization of the test substance purity. 006611 REFERENCES This study was conducted by the 3M Company, Environmental Laboratory, St Paul, MN, Lab Request Number B1498-2.

The solubility results for FC-43 (perfluorotributylamine) o f less than 2 mg/1 are somewhat surprising. In addition to my previous comments, I might remark that this compound has an appreciable vapor pressure. One sample which I have taken data on had a vapor pressure which, if the solubility results are taken at face value, would indicate that the molar concentration in the vapor phase would be substantially high1than that in water. If this is the case then an appreciable danger exists for volatilization/adsorption o f the amine vapor from a water sample. This sample should be definitely remeasured with proper precautions against vapor loss. The solubility results for FX-8 o f less than 2 mg/1 are also surprising. This compound is identified as a perfluorooctane sulfonate and is presumably closely related to FC-95 which has a substantially higher apparent solubility. Both sets o f results are identified as approximate so it is difficult to assess their reliability. M ore detailed experiments should performed. Edwin E. Tucker, Ph.

FC-43 1. Add an accurately measured volume of water to almost fill 2 sucilciblo glass containers. 2. Add sufficient FC-43 to these 2 containers so that if the FC-43 were water miscible its concentrations would bring the PC-43 concentration to 250 mg/1 and 500 mg/1, respectively. 3. Seal the containers. 4. Separate the containers from magnetic stirrers using styrofoam sheets, and stir at a slow rate for >6 hours. 5. Turn off the stirrers and let the contents settle over night. 6. Pipette 2 samples from just below tho surface of each container to completely fill small sample vials, and seal. Keep vials at room temperature. 7. Analyze the samples by TOC within 24 hours of sampling. Quickly reseal the sample vials. Record temperature pf sample storage, location. 2 Y `C S^<v t sf.//-} k . / t F k - r >- F c - i / S 8. Let the vial samples sit undisturbed at room temperature for 1-2 weeks. Then, without shaking or mixing reanalyze the TOC. Again record temperature of sample storage location. 006615 Form 10620-8-8 PWO Sample Description Environmental Lab -- Work Sheet UJAr t d SouCBltlTV - T o c , KTHob Lab Request N o _____ (Page________ of D a te :__ Analyst: L l . .
