In IUPAC nomenclature hexane is the unbranched isomer (n-hexane), the other four structures are named as methylated derivates of pentane and butane. Hexanes are significant constituents of gasoline. They are all colorless liquids at room temperature, odorless when pure, with boiling points between 50 Â°C and 70 Â°C. They are widely used as cheap, relative safe, largely unreactive and easily evaporated non-polar solvents. Hexane - dynamic viscosity over temperature.
Obtain a closed-tip syringe and record the exact volume of air in the syringe and the room temperature. 2. Add approximately 400ml of water to each of the beakers. Insert the syringe into the water to test the water depth.llow about 5 minutes for the syringe of air to attain the same temperature as water. Record the temperature of water bath and the volume of the air in the syringe. 6. Add a few small pieces of ice to the room-temperature beaker to lower the temperature of the water to approximately 10-15Â°C.
