Additional information
Tripropenyl succinic anhydride is a clear brown liquid.
According to OECD102 study the melting point of Tripropenyl succinic anhydride is -31 ± 3 °C.
According to OECD103 study the boiling point of Tripropenyl succinic anhydride is 311 ± 9 °C at 101.9 kPa.
According to OECD109 study the density of Tripropenyl succinic anhydride is 1.0197 ±0.0002 g/cm³ at 20°C and the relative density is D420 = 1.02
According to REACH regulation - Annex VII - Chapter 7.8 - Column 2 a partition coefficient study does not need to be conducted if the substance reacts with the solvents during the test. The substance is hydrolytically unstable and reacts rapidly with water and with n-octanol. Therefore the test could not be performed. Instead a test with the hydrolytical product Tripropenyl succinic acid was performed.
According to OECD107 shake flask method the log pow of Tripropenyl succinic acid is determined to be 2.79.
According to REACH regulation - Annex VII - Chapter 7.7 - Column 2 a water solubility study does not need to be conducted if the substance is hydrolytically unstable at pH 4, 7 and 9 (half-life less than 12 hours). The half live rates are <2h at any measured pH in a OECD111 study (s. IUCLID chapter 5.1.2). Therefore the test could not be performed. Instead a test with the hydrolytical product Tripropenyl succinic acid was performed.
According to ISO 4311 the critical micelle concentration of Tripropenyl succinic acid is 0.9 ± 0.09 g/L at 20°C. For ecotoxicological purposes this value should be taken as the water solubility.
From the result of the preliminary test performed according to OECD105 it can be concluded that Tripropenyl succinic anhydride is miscible with n-octanol at every ratio. Gas chromatograms of solutions of the test substance in n-octanol show that esterification takes place.
According to OECD115 study the surface tension of Tripropenyl succinic anhydride is 42.0 ± 0.6 mN/m at a concentration of 90% of the saturation concentration at 20°C.
The flash point of Tripropenyl succinic anhydride, measured with the equilibrium method, is 67 ± 2 °C.
The Auto-ignition Temperature of the test item according to the auto-ignition test conditions in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.15. is 315 °C.
There are no structural alerts within tripropenyl succinic anhydride and great experience in handling and use give evidence that no Pyrophoricity and Flammability on contact with water properties give any concern. For liquids the Flammability is described by the Flash Point.
Tripropenyl succinic anhydride is a is considered to have no explosive properties as there are no chemical groups associated with explosive properties present in the molecule.
Tripropenyl succinic anhydride is a is considered to have no oxidising properties as there are no halogen or oxygen atoms bond to nitrogen or oxygen.
Tripropenyl succinic anhydride is a is considered to be stable in organic solvents.
According to REACH regulation - Annex IX - Chapter 7.16 - Column 2 a dissociation constant study does not need to be conducted if the substance is hydrolytically unstable at pH 4, 7 and 9 (half-life less than 12 hours). The half live rates are <2h at any measured pH in a OECD111 study (s. IUCLID chapter 5.1.2). Therefore the test could not be performed. Instead a dissociation constant with the hydrolytical product Tripropenyl succinic acid was determined.
The calculated pKa values of Tripropenyl succinic acid at 25°C are:
pKa1 (BH- + H+ ⇌ BH2): 5.14 ± 0.19
pKa2 (B-- + H+ ⇌ BH-): 4.34 ± 0.23
The viscosity tripropenyl succinic anhydride is: 108.4 ± 2.7 mPa.s at 20°C 32.3 ± 0.8 mPa.s at 40°C.
