Our relevant product
We have recently developed a new ionic liquid "ILA48-32" for dissolution of cellulose, which is suited for developing regenerated cellulose materials.
Structure
Characteristics
- It is a liquid at room temperature and easy to handle.
- Cellulose can be dissolved in ILA48-32 in high concentrations, up to 25 wt%.
- The degree of polymerization (DP) loss of regenerated cellulose is lower than chloride-containing quaternary ammonium salt.

| Cellulose solubility (wt%)* | Degree of polymerization after regeneration** | |
|---|---|---|
| ILA48-32 | 25 | 245 |
| Quaternary ammonium salt | 25 | 20 |
*The mixture of the pulp and the ionic liquid was heated to 100℃ and stirred for 1 hr.
**The pulp with a degree of polymerization of 363 was used.
The cellulose was regenerated by casting in methanol bath at room temperature.
Examples of use
- Cellulose regeneration process
- Antistatic agent for aqueous coating
- Functional polymer composite materials
