Product Description:

1-Ethyl-3-methylimidazolium chloride ([EMIM]Cl) is a prototypical ionic liquid composed of a 1-ethyl-3-methylimidazolium cation and a chloride anion. It is a colorless to pale yellow, hygroscopic solid at room temperature, with a melting point typically below 100°C, classifying it as a room-temperature ionic liquid (RTIL). Its primary and most significant application is as a versatile solvent and reaction medium in material science and green chemistry. It is extensively used in the synthesis and processing of cellulose, acting as an excellent solvent to dissolve and derivatize this biopolymer. Furthermore, [EMIM]Cl serves as a key precursor or component in the preparation of other functional ionic liquids and advanced materials, including electrolytes for batteries and supercapacitors, catalysts, and separation media. Its properties, such as low volatility, high thermal stability, and good ionic conductivity, make it valuable in these fields. As a foundational ionic liquid, it also finds use as a specialized reagent or catalyst in organic synthesis, particularly in reactions where its dual role as a solvent and a promoter is advantageous, such as in Friedel-Crafts acylations or Diels-Alder reactions.
