BACK TO MAIN MELTING POINT TEST SUBSTANCE Identity: Decafluoro(pentafluoroethyl)cyclohexanesulfonate, DEA salt; may be referred to as CS-2070. When dissolved in water may also be referred to or as CS-2151 or FC-90. (DEA salt of perfluoro(ethylcyclohexyl) sulfonate, [C2F5-CF(CF2CF2)2CFSO3-][H2N(CH2CH2OH)2+]) Remarks: There is no 3M production lot number available for this sample. The test substance is reported to be the dried solid from CS2151 which is 25% CS-2070 solids in water. METHOD Method: CIPAC Method #MP2 employing a Thomas Hoover Uni-Melt apparatus. GLP: No Year completed: 1981 RESULTS Melting point value in C: Liquid first observed at 75oC Complete melt at 145oC Decomposition: No Sublimation: No Remarks: The sample was heated in air at 10oC per minute. It appears waxy at room temperature. The sample was soft through the melting range and appeared gel-like. Benzoic acid melted at 122oC. This study indicated only 5% weight loss by 280oC and stable to 200oC. A 50% weight loss occurs at about 370oC. CONCLUSIONS The sample was first observed to melt at 75oC and completely melted at 145oC. The midpoint of the melting range was 110oC. Submitter: 3M Company, Environmental Laboratory, P.O.

The test sample purity was not characterized. REFERENCES Study conducted at the 3M Commercial Chemicals Analytical Laboratory, Analytical Report number 244, July 29, 1981.
