Electric Literature of 7098-07-9, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 7098-07-9, name is 1-Ethyl-1H-imidazole belongs to imidazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.
As a general procedure for preparing Bronsted acidic ILs, the synthesis of 1-(4-butylsulfonic)-3-ethylimidazolium hydrogensulfate ([EImC4SO3H][HSO4]) is given as an example. To 1-ethylimidazole (10 g, 0.104 mol) in 50 mL of toluene, 1,4-butanesultone (14.2 g, 0.104 mol) dissolved in 50 mL of toluene was added dropwise under a dry nitrogen gas atmosphere. The resulting solution was refluxed with stirring at 60 °C for 24 h.After removing toluene, the product was washed thrice with 100 mL of diethyl ether to yield 1-(4-butylsulfonate)-3-ethylimidazol([EImC4SO3]) as a white powder. After dissolving [EImC4SO3] (20 g, 8.6102 mol) in 50 mL of methanol, sulfuric acid (0.84 g, 8.6102 mol) was added dropwise in an ice bath. The resulting solution was refluxed with stirring at 60 °C for 24 h. Following the reaction, methanol was removed by evaporation and then under reduced pressure, giving1-(4-butylsulfonic)-3-ethylimidazolium hydrogen sulfate ([EImC4SO3H][HSO4]) as a viscous liquid.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1-Ethyl-1H-imidazole, other downstream synthetic routes, hurry up and to see.
