Results and discussion
Any other information on results incl. tables
The reaction enthalpy (DHREAK) was calculated from the standard formation enthalpies (DHFORM) of the substances involved. The data comes from the NBS tables. In the two comparative reactions I assumed the value for ionized HCl in aqueous solution for DHFORM for HCL. The reaction enthalpy of the AlCl3 reaction is the highest, so one can definitely speak of “reacting violently with water”. The specified temperature increases are incorrect (too high): The increase in Cp’s with increasing temperature is not taken into account and the Cp of the HCl that is produced is uncertain (dissociation, concentration dependency). As a relative comparison, the values are a first indication. TiCl4 and CH3COCl are legal classified with EUH014.

Applicant's summary and conclusion
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.
