Additional information
The multi-constituent substance " Reaction mass of dodecane-1-thiol and tridodecyl trithiophosphite" is a clear oily liquid with sulphur like mild odour at 101325 Pa and 20 °C.
The melting point of the substance is 19.8 ° C and , after melting, the decomposition of test item starts at 300 °C with a peak at 337.98 °C correlated to ΔH= 58.16 J/g. Considering the low melting point of the substance, it is possible that just below 20 °C the substance starts to solidify. All tests performed for REACH registration purpose used the substance as liquid form.
The experimental density of the compound is 0.895 g/cm^3 at T= 25 °C.
The test item is a liquid so the particle size is waived.
Some physical-chemical properties , such as vapour pressure and logKow, of this multi-constituent substance were estimated considering the SMILES notation for its most abundant component Tridodecyl trithiophosphite and their values are respectively 1.53* 10^-12 Pa at T= 25 °C and log Kow > 10.
The multi-constituent substance "Reaction mass of dodecane-1-thiol and tridodecyl trithiophosphite" is slightly soluble in water (experimental water solubility: 96.3 mg/l T= 20 °C pH= 8.2).
Surface activity is not expected property for this substance.
The experimental flash point of the test item is higher than 200 °C so it is not autoflammable and it is not considered a flammable liquid according to the CLP Regulation (EC n.1272/2008).
This substance is not explosive and it is not oxidising considering the chemical structure of its main components (they do not contain explosive groups, oxygen or alogen atoms).
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).
