Description of key information
The submission substance is classified as
Flammable liquid category 3.
There are no further classification requirements for the submission substance with regard to physico-chemical properties.
Relevant key information is given in the endpoint summaries on the respective properties.
For a summary and conclusion with regard to overall physical hazards and respective classification and labelling requirements, see below!
Additional information
A full set of physico-chemical information is available with all of the essential parameters determined according to established testing guidelines. Due to the fast disintegration of Step 2 catalyst by hydrolysis/oxidation, water solubility could not be determined and partition coefficient n-octanol-water was calculated for the final transformation products LHP-fin1 and LHP-fin2. Classification issues are discussed in the relevant endpoint summaries in more detail. Here, only a brief summary is given:
Based on a flash point between 23°C and 60°C (46°C at 1013 hPa), the submission substance is classified according to REGULATION (EC) No. 1272/2008 (CLP) as well as UN-GHS rev. 7 (2017) as
Flammable liquid category 3.
Pyrophoric properties as well as formation of flammable gases in contact with water can be excluded based on experience from the handling and use of the substance.
With regard to self-heating, according to (1) "In general, the phenomenon of self-heating applies only to solids. The surface of liquids is not large enough for reaction with air and the test method is not applicable to liquids. Therefore liquids are not classified as self-heating."
Self-reactiveness as well as explosiveness could be reliably excluded due to a valid study on the exothermic decomposition energy (DSC) applying screening procedures given in (2): the submission substance is neither self-reactive nor explosive based on an exothermic decomposition energy of 64.53 J/g at an onset temperature of 65.87 °C.
Oxidizing properties can be excluded based on substance characteristics: the substance is highly sensitive to oxygen (oxidation) and must be stored/treated under inert gas. As such, it cannot act as an oxidant.
In addition, classification for corrosiveness to metals was checked. According to (1), corrosiveness to metals may be relevant for substances with acidic or basic functional groups, substances containing halogen or substances able to form complexes with metals. The submission substance does not contain any acidic or basic moieties. It does contain 2.4% halide in the form of zinc halide. However, the submission substance is no electrolyte and the halide present is bound to Zn associated with the complex, i.e. the halide is not present as a free ion. Only free halide ions in the form of an electrolyte may effect metal corrosion. While it complexes transition metal, the ligand is already saturated with the preferred transition metal, such that complexation of any metal tank material can be excluded. Further, the substance is purely organic and devoid of any water. The substance is highly sensitive to oxygen (oxidation) and must be stored / treated under inert gas. As such, it cannot act as an oxidant and thus oxidative damage to metal surfaces can be excluded. In conclusion, metal corrosiveness can be excluded from the characteristics of the submission substance and as a consequence, testing of metal corrosion is scientifically unnecessary.
Overall, the substance has to be classified as flammable liquid Cat. 3. No other classification requirements with regard to physical hazards do exist.
