| Hazard Information | Back Directory | [General Description]
Clear colorless liquid. | [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. | [Air & Water Reactions]
Insoluble in water. | [Chemical Properties]
clear colorless liquid | [Uses]
2,4-Dichlorotoluene was used as an oxidant and a solvent during anaerobic catalytic oxidation of secondary alcohols by using an in situ (N-heterocyclic carbene)-Ni(0) system. It was used as growth supplement in the culture media of Ralstonia sp. strain PS12. It was used to develop a sensitive method based on solid-phase microextraction followed by gas chromatography-tandem mass spectrometry for the analysis of chlorotoluenes in water samples. | [Definition]
ChEBI: 2,4-Dichlorotoluene is a dichlorobenzene. | [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. | [Synthesis Reference(s)]
