176°F

Flash Point：

12°F

Water Solubility：

0.07%

Storage Conditions：

Conditions for safe storage, including any incompatibilities: Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage.

Vapor Pressure：

Vapour pressure, kPa at 20°C: 10

Vapor Density：

2.77

Flammability characteristics：

Class IB Flammable Liquid: Fl.P. below 73°F and BP at or above 100°F.

Explosive limit：

vol% in air: 1.3.1

Odor：

Aromatic odor

Taste：

Taste threshold in water is 0.5-4.5 mg/l.
