2-methyl-4-nitro-benzonitrile - Introduction
It is an organic compound with the formula C8H6N2O2. It is a yellow crystal with an aromatic smell of benzene.
Nature:
1. It is a stable solid at room temperature.
2. It has low solubility, insoluble in water, and better solubility in general organic solvents.
3. The compound may decompose when heated and produce harmful gases.
Use:
It is mainly used as an intermediate in organic synthesis. It can be used in the synthesis of benzyl nitrile, benzyl alcohol, benzoyl chloride and other organic compounds. In addition, it can also be used in the production of pesticides and dyes.
Preparation Method: The preparation of
is generally obtained by reacting p-methylbenzonitrile with nitric acid. The specific steps are as follows:
1. Under acidic conditions, methylbenzonitrile reacts with concentrated nitric acid to produce 2-nitro-4-methylbenzonitrile.
2. The resulting product was crystallized to obtain a solid.
Safety Information:
is a toxic substance that is irritating and corrosive. Contact with skin and eyes may cause skin irritation and eye damage. During use, preparation and storage, appropriate safety measures should be taken, such as wearing protective gloves and glasses, to ensure good ventilation.
