4,4''-Dinitro-p-terphenyl - Introduction
4,4 "-Dinitro-p-terphenyl, also known as 4,4"-Dinitro-p-terphenyl, chemical formula is C18H12N2O4. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: 4,4 "-Dinitro-p-terphenyl is a colorless to yellow crystalline powder.
-Melting point: Its melting point is about 295-300 ° C.
-Solubility: It is almost insoluble in water, but can be dissolved in organic solvents.
Use:
-Explosiveness: Because 4,4 "-Dinitro-p-terphenyl has high energy density and explosiveness, it can be used as one of the components of high explosives.
-Pigment: It can be used as an intermediate for pigments and dyes, for example, for the preparation of certain red dyes.
-Other applications: In addition, 4,4 ''-Dinitro-p-terphenyl is also used in the preparation of optical materials, optical fibers and liquid crystal displays.
Method:
The preparation method of 4,4 "-Dinitro-p-terphenyl is mainly based on the chemical reaction of p-triphenylmethane (p-terphenyl). A commonly used method of preparation is by reacting p-trityl magnesium bromide with silver nitrate to give 4,4 "-dinitro-p-terphenyl.
Safety Information:
-Because 4,4 ''-Dinitro-p-terphenyl are explosive and highly toxic, they must be handled and stored with care.
-During operation and storage, contact with combustion agents, combustibles, organics or oxidants must be avoided.
-Wear protective glasses, gloves and respiratory protection when using 4,4 ''-Dinitro-p-terphenyl.
-After contact with 4,4 ''-Dinitro-p-terphenyl, immediately rinse the affected area with plenty of water and seek medical attention immediately.
-Waste must be disposed of properly in accordance with local regulations and cannot be discarded at will.
