What is the preparation method of Diphenyliodonium Hexafluoroarsenate (1-)
The method of preparing diphenyl iodide hexafluoroarsenate requires the combination of diphenyl iodide salt and hexafluoroarsenate. The first diphenyl iodide salt is obtained by reacting iodobenzene with an oxidizing agent, such as potassium persulfate, hydrogen peroxide, and the like, in a suitable solvent, such as glacial acetic acid and acetonitrile, under the condition of heating or the presence of a catalyst. The resulting reaction liquid is treated, such as cooling, filtration, crystallization, etc., to obtain diphenyl iodide salt.
The hexafluoroarsenate is taken at times, and arsenic trioxide is often reacted with fluorinating agents such as hydrofluoric acid and fluorine gas to obtain hexafluoroarsenic acid, which is then reacted with alkali metal salts or ammonium sal
Then, mix the prepared diphenyl iodide salt and hexafluoroarsenate in a suitable solvent, such as acetone and dichloromethane, according to an appropriate molar ratio. Stir to make the two fully react. After the reaction is completed, purified by evaporation solvent, recrystallization, etc., pure diphenyl iodine hexafluoroarsenate can be obtained. During operation, attention should be paid to safety. Because some of the reagents used are toxic, corrosive or oxidizing, they must be carried out in accordance with regulations to ensure the safety of people and the environment.
Diphenyliodonium Hexafluoroarsenate (1-) What are the precautions during use?
When using Diphenyliodonium Hexafluoroarsenate (1-), there are many things to pay attention to.
This is a class of compounds with special activity and is quite active in nature. First, it needs to be stored with caution. Because it is quite sensitive to environmental factors, it should be placed in a cool, dry and well-ventilated place, away from heat sources and fire sources, to prevent thermal decomposition or dangerous reactions. And it must be stored separately from other chemicals, especially reducing substances, strong acids and alkalis, etc., to avoid dangerous interactions.
Second, when using, it must be well protected. Appropriate protective clothing should be worn, including laboratory clothes and protective gloves, and the material should be able to resist the erosion of this substance. Eye protection is also indispensable. Wear goggles to prevent it from splashing into the eyes and causing serious damage to the eyes. Because the substance may be toxic and irritating, appropriate respiratory protective equipment should also be worn to prevent inhalation of its dust or volatile gases.
Third, the operation process should be rigorous. Just take an appropriate amount to avoid waste, and the operation should be carried out in the fume hood, so that the harmful gases that may be generated can be quickly discharged. If you accidentally come into contact with the skin or eyes, you need to rinse with plenty of water immediately and seek medical attention in time. After use, properly dispose of the remaining substances and appliances, and dispose of the residues in accordance with relevant regulations. Do not discard them at will to avoid polluting the environment.
In conclusion, when using diphenyl iodide hexafluoroarsenate, every step of the operation should be handled with care and in strict accordance with the regulations to ensure the safety of personnel and the smooth operation of the experiment.
