2,4-Dichlorotoluene Usage And Synthesis

Chemical Properties

clear colorless liquid

Synthesis Reference(s)

Tetrahedron Letters, 32, p. 2759, 1991 DOI: 10.1016/0040-4039(91)85078-J

General Description

Clear colorless liquid.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Simple aromatic halogenated organic compounds, such as 2,4-Dichlorotoluene, 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.

Purification Methods

Recrystallise 2,4-dichlorotoluene from EtOH at low temperature or fractionally distil it. [Beilstein 5 IV 815.]
