The solution was tempered at 20°C for 5 minutes and then the residue was filtered off by membrane filtration. 90 ml of the filtered solution were filled up to 1 00 ml with purified water. The surface tension of the resulting solution was measured. The surface tension of the purified water used was also measured for reference.

### Another 20 mg of test item were mixed with 500 ml of water at 23°C. After stirring for three days at 23°C, brown amounts of test item were visible adhered at the magnetic stirrer. Thus the water solubility of the test item was estimated to be 

### < 40 mgil. Remark: This pre-testing merely shows that c. 40 mg of test item are not completely soluble in one liter of water. As the test item is not a pure compound but a mixture of compounds with possibly different properties, it may be that the water solubility of fractions of the test item is higher than 40 mgil. The determinations were done according to Annex Commission Directive 92i69iEEC, Part A.6 and OECD Guideline for the Testing of Chemicals, 105, flask method. In order to avoid evaporation of parts of this hydrocarbon mixture, the working temperature was decreased from

### The test item is a mixture of substances of different volatility, in consequence the dynamic method according to OECD Test Guideline 103 is not suitable. Therefore the determination of the Normal Boiling Point was carried out via vapour pressure measurement by the static method according to OECD Test Guideline 1 04.

. Therefore the normal boiling temperature could not be determined, because measurements of vapour pressures at higher temperatures were not possible. The test item was solid with a liquid portion at 25°C. In the measured temperature range it was liquid. For vapour pressure curve see page 25.
