Properties of o-Nitrotoluene

Nitration of toluene with mixed acid gives mixed nitrotoluenes, which are mainly o-nitrotoluene (about two thirds) and p-nitrotoluene (about one third) the pure chemicals can be obtained through separation. After toluene is added to a reactor and cooled to 25 °C, the previously mixed acids were added (25-30 % of nitric acid, 55-58 % of sulfuric acid and 20-21 % of water) and the temperature adjusted to less than 50 °C. After 1-2 h of stirring and then 6 h of static storage, the

Properties. o-Nitiotoluene [88-72-2] is a clear yeUow liquid. The solid is dimorphous and the melting points of the a- and P-forms ate —9.55 and —3.85 C, respectively. o-Nitrotoluene is infinitely soluble in benzene, diethyl ether, and ethanol. It is soluble in most organic solvents and only slightly soluble in water (0.065 g in 100 g of water at 30°C). The physical properties of o-nitrotoluene are hsted in Table 9.
