Benzene, 1-ethynyl-2-nitro- - Introduction
It is an organic compound with the molecular formula C8H5NO2 and the structural formula C6H5C≡CNO2. The following is a description of its nature, use, preparation and safety information:
Nature:
It is a yellow crystal or yellow crystalline powder with a pungent odor. It is insoluble in water, slightly soluble in ethanol and ether, soluble in benzene and methylene chloride.
Use:
is an important organic synthesis intermediate, often used in the synthesis of other organic compounds. It can be used to synthesize dyes, fluorescent whitening agents, detonating drugs and drugs.
Method: The preparation of
is usually obtained by benzene nitration and subsequent ethynylation. First, benzene is converted to 2-nitrobenzene by a nitration reaction in the presence of nitric acid and concentrated sulfuric acid. Then, 2-nitrobenzene reacts with sodium ethoxide or sodium picrylate, and ethynylation occurs.
Safety Information:
It is an irritant substance that has an irritating effect on the eyes, skin and respiratory tract. Avoid inhalation, contact with skin and eyes during use. Appropriate personal protective equipment such as gloves, goggles, etc. should be worn during operation. Avoid contact with oxidizing agents and strong acids to avoid dangerous reactions. Avoid direct sunlight during storage. In case of leakage, appropriate measures shall be taken for cleaning and treatment.
