Reactivity Profile
Simple aromatic halogenated organic compounds, such as 2,4-DICHLOROTOLUENE(95-73-8), are very unreactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Materials in this group may be incompatible with strong oxidizing and reducing agents. Also, they may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.
Preparation
2,4-Dichlorotoluene is synthesized by diazotization and chlorination with 2,4-diaminotoluene as raw material. First, hydrochloric acid and water into the reaction pot, heated to 50°C, stirring under the dissolution of 2,4-diaminotoluene, then hydrochloric acid and cuprous chloride into the pot, the 1% sodium nitrite solution evenly added, the temperature is maintained at about 60°C, resting stratification, the lower layer of crude product washed with water to neutral, add alkali to alkaline, and then water to remove the alkali, divided 2,4-dichlorotoluene crude product, water distillation of finished products.
