Flammability :

From the experimental values of flammability, bis(pentane-2,4-dionato-O,O')bis(propan-2-olato)titanium ignited when the flame of bunsen burner having temperature of 950 degC was brought in contact with it. Thus it can be concluded that the substance is flammable only at high temperature of about 950 degC. However since such high temperatures are not found under normal circumstances of transportation and use.

Explosiveness :

According to theoretical considerations based on chemical structure, bis(pentane-2,4-dionato-O,O')bis(propan-2-olato)titanium does not possess explosive properties. The reason for this is there are no chemical groups associated with explosive properties in bis(pentane-2,4-dionato -O,O')bis(propan-2-olato)titanium. Thus, as per column 2 of Annex VII this end point was considered for waiver.

Oxidising properties :

Bis(pentane-2,4-dionato-O,O')bis(propan-2-olato)titanium was found to have oxidising property since 45.7 ml of KMnO4 was required for getting the end point of the redox titration for 100 gof bis(pentane-2,4-dionato-O,O')bis(propan-2-olato)titanium.

Stability in organic solvents and identity of relevant degradation products :

Bis(pentane-2,4-dionato-O,O')bis(propan-2-olato)titanium was found to be stable in organic solvent dichloro methane and no degradation products were formed after 24 hours as evident from the GC-MS chromatogram obtained at 0 hours and that obtained after 24 hours.

pH :

1% by volume solution of bis(pentane-2,4-dionato-O,O')bis(propan-2-olato)titanium was found to exhibit a pH of 5.01 at 24 degC. Thus 1% by volume solution of bis(pentane-2,4-dionato-O,O')bis(propan-2-olato)titanium is Relatively Acidic in nature.
