Usage

General Description

3,4-dimethyl-2,6-dinitrophenol, also known as DNP, is a highly toxic and potentially lethal chemical compound. It is commonly used as a pesticide and in the production of dyes, wood preservatives, and explosives. DNP has also been used as a weight loss aid, although it is not approved for this purpose and is illegal to sell for human consumption in several countries. Ingesting even small amounts of DNP can lead to severe health effects, including hyperthermia, tachycardia, nausea, vomiting, and potentially death. Due to its high toxicity, DNP is considered a dangerous substance and should be handled with extreme caution.

Nitration method for aryl phenol or aryl ether derivative

The invention relates to a nitration method for an aryl phenol or aryl ether derivative. The method comprises the steps of stirring an aryl phenol or aryl ether compound, nitrate, trimethylchlorosilane (TMSCl) and a copper salt in an acetonitrile solution in air at room temperature, simultaneously, monitoring extent of reaction through a TLC dot plate, removing a solvent from a mixture by a rotaryevaporator after a substrate is consumed completely, and carrying out purification through a silica-gel column, thereby obtaining a nitroolefin derivative. Meanwhile, the selective mono-nitration orbis-nitration of the substrate can be achieved through controlling equivalent weight of the nitrate. Compared with the prior art, the nitration method disclosed by the invention has the advantages that the consumption of strong-acid substances is avoided, the reaction conditions are mild, the yield is high, the applicable range of the substrate is wide, reaction activity is free of obvious attenuation after an amplified reaction, and an excellent yield is still obtained, so that the method has an obvious industrial application value.
