1-(1-Methylethyl)-2-nitrobenzene - Introduction
Nitrocumene(Nitrocumene), also known as nitrotert-butylbenzene, is an organic compound. The following is a description of the properties, uses, preparation and safety information of the compound:
Nature:
-Appearance: The Nitrocumene is a colorless to light yellow liquid.
-Density: Its density is about 1.1g/cm³.
-Boiling point: Its boiling point is about 182-183°C.
-Ignition point: Its ignition point is about 80°C.
-Solubility: It can be dissolved in organic solvents such as ethanol, ether and benzene, but it is insoluble in water.
Use:
-Explosive: Nitrocumene is an important explosive component that can be used to prepare explosives and gunpowder.
-Chemical synthesis: It can be used as an intermediate in organic synthesis and used to prepare other organic compounds.
-Preservative: It can be used as a preservative to protect some products that are easily contaminated by microorganisms.
Preparation Method:
Nitrocumene is usually prepared by nitration reaction, the specific steps are as follows:
1. Mix cumene with dilute nitric acid and stir at low temperature.
2. slowly add a mixture of concentrated nitric acid and sulfuric acid to the reaction system, and control the reaction temperature at 20-30°C.
3. After the reaction is completed, the mixture is separated, washed with water, and then the remaining acid is neutralized with an alkali solution, and the product is extracted.
4. Distilling the extracted organic layer to obtain pure Nitrocumene.
Safety Information:
Nitrocumene is an organic nitrate compound with high explosive and toxicity. The following are some safety precautions for use and storage:
-Avoid contact with skin, eyes and respiratory tract. Appropriate protective equipment, such as gloves, goggles and respiratory protection, should be worn.
-Use should maintain good ventilation conditions.
-Keep away from fire and heat sources to prevent fire or explosion.
-Store in an airtight container, away from sunlight and high temperatures.
-Follow the relevant regulations when dealing with waste, do not discharge at will.
Please note that Nitrocumene is a dangerous chemical and should only be used by personnel with professional knowledge in an appropriate laboratory environment.
