Description

Nitrotoluene is formed in 3 isomeric forms. The o-and m-forms are yellow liquids or solids. The p-form is a pale yellow crystalline solid. All have weak aromatic odors. The Odor Thresholds are: 0.05 mg/L (o-isomer); 1.74 ppm (m-isomer).Exists as either a yellow solid crystal or liquid. Melting point 32 to 59°F. Insoluble in water and soluble in alcohol. Denser than water. Toxic by ingestion, inhalation or skin contact. Flash point 223°F. Boiling point 428°F. Produces toxic oxides of n
