Description of key information

Additional information

The physico-chemical properties of the members of the category, including HXL-833, are summarized in the table below. The data show, that all substances have similar physico-chemical propererties. Therefore, the category approach is justified.

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).
