Product Description
1-Ethyl-3-methylimidazolium Acetate, CAS 143314-17-4, is a room-temperature ionic liquid (IL) renowned for its exceptional solvent properties. Often abbreviated as [EMIM]OAc, it is highly effective at dissolving a wide range of biopolymers, most notably cellulose, chitin, and lignin. This capability makes it a key “green solvent” in the fields of biomass processing, biofuels, and sustainable chemistry. Its low volatility, high thermal stability, and recyclability offer significant advantages over traditional volatile organic solvents.

- Biomass Pretreatment: A powerful solvent for the dissolution of lignocellulosic biomass (e.g., wood, agricultural waste) to separate cellulose, hemicellulose, and lignin for biofuel and biochemical production.
- Cellulose Processing: Used to dissolve cellulose for the spinning of fibers, creation of films, and preparation of composite materials.
- Green Chemistry: Acts as a recyclable and non-volatile solvent and catalyst for various organic syntheses, including acetylation and esterification reactions.
- Polymer Synthesis: Employed as a medium for synthesizing and modifying polymers, such as starch-grafted copolymers.
- Electrochemistry: Utilized as an electrolyte in the fabrication of batteries and supercapacitors due to its high ionic conductivity.
