Additional information
The boiling point of Leuco Sulfur Black 1 is determined to be 99.9 °C ± 0.1 ° C which is equal to 373.1 K ± 0.1 K. The atmospheric pressure during the measurements was 100.4 kPa (preliminary test) and 99.8 kPa (main tests). The boiling point of Leuco Sulfur Black 1 is influenced by its high water content. It can be assumed that the measured value corresponds to water only.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
