2 Cleveland open cup method

3Measured values are higher than expected. This was probably caused by the small amount of water present in the samples. Therefore, where possible, vapour pressures were calculated based on their measured boiling temperature using the Modified Watson Correlation method described by Lyman (Lyman, Reehl, Rosenblatt (eds.), "Handbook of chemical property estimation methods", McGraw-Hill Book Company, 1990).
