Product overview & key benefits
1,3-Dioxolane is made from formaldehyde and ethylene glycol. It is a strong, water-miscible solvent that dissolves many resins and polymers, and it is used as a solvent and extractant for oils and fats and as a cleaning solvent. In lithium batteries it is a co-solvent in electrolytes, particularly for lithium-metal and lithium–sulfur cells. With 1,3,5-trioxane it is copolymerized to make POM copolymer.
For battery use, water and impurity limits are tighter than for solvent grades; tell us which you need.
Battery and POM grades
Used as a lithium-battery electrolyte solvent and as a comonomer with trioxane for POM.
Specified on your terms
We quote against your assay, water and stabilizer requirements and send the batch COA for each lot.

Selection & comparison
Choosing the right 1,3-dioxolane grade
| Your requirement | What usually works |
|---|---|
| Lithium-battery electrolytes | Battery grade; specify water (ppm) and metal ions |
| Solvent and extraction | Standard ≥ 99.9% grade |
| POM copolymer | Polymer grade; agree impurity limits |
| Replacing an existing supplier | Send your current TDS or COA; we quote against the parameters you approve |
Packaging & storage
Packaging
Tell us the drum or IBC size you need; battery grade is usually packed under nitrogen.
Storage
Keep containers closed under a dry, inert atmosphere, cool and away from ignition sources. Like other ethers it can form peroxides on long storage.
Transport
Flammable liquid (UN 1166, Class 3, PG II).
From first email to approved supply
Name the end use
Battery, solvent or POM: water and impurity limits follow from it.
Compare the numbers that matter
Assay, water, peroxide and, for batteries, metal ions.
Protect the material
Keep it dry and under nitrogen once opened; water pick-up matters most for battery grades.
Trial, then lock the spec
Run a sample in your own process and keep the approved lot COA as the reference for contract limits.
Tell us your requirement. We match the grade.
Tell us your application, the quantity and the destination port. Add your current specification and we will quote against it.
