Vapour pressure:

The estimated vapour pressure of the test substance 2,3-bis[(4-methylbenzoyl)oxy]succinic acid (32634-68-7) at 25deg C was 5.5E-009 Pa.

Partition coefficient:

The octanol- water partition coefficient of the test substance+)-Di-p-toluoyl-D-tartaric Acid(CAS no. 32634 -68 -7 ) was estimated using OPERA V1.02.

The estimated LogPow of the test substance+)-Di-p-toluoyl-D-tartaric Acidwas 2.97 dimensionless. On the basis of log Pow value it can be concluded that test chemicall+)-Di-p-toluoyl-D-tartaric Acid is hydrophilic in nature.

Water solubility:

The estimated water solubility of test substance 2,3-bis[(4-methylbenzoyl)oxy]succinic acid (32634-68-7) at 25 deg C was 112.55 mg/l.

Surface tension:

Based on the prediction done by ACD labs, the surface tension for chemical 2,3-bis[(4-methylbenzoyl)oxy]succinic acid (32634-68-7) was predicted to be 60.4 ± 3.0 dyne/cm.

Flash point:

The flash point of 2,3-bis[(4-methylbenzoyl)oxy]succinic acid  (32634-68-7) is estimated 223.2 ± 25.0 °C

Autoflammability:

2,3-bis[(4-methylbenzoyl)oxy]succinic acid  (32634-68-7) did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 2,3-bis[(4-methylbenzoyl)oxy]succinic acid  (32634-68-7) is not auto-flammable.

Flammability:

2,3-bis[(4-methylbenzoyl)oxy]succinic acid  (32634-68-7) does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that 2,3-bis[(4-methylbenzoyl)oxy]succinic acid (32634-68-7) is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 2,3-bis[(4-methylbenzoyl)oxy]succinic acid  (32634-68-7) was considered non-flammable.

Explosiveness:

The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties.

Oxidising properties:

The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidizing properties and hence the classification procedure does not need to be applied.
