Useful:

• Chemical Classes: Other Classes -> Sulfur Compounds
• Canonical SMILES: CCOS(=O)OCC
• Uses: Diethyl sulfite (DES) is used as a film forming and high temperature additive for electrolytes in lithium ion batteries. It improves decomposition resistance of the electrolyte. Diethyl sulfite is also used as solvent for lithium bis(oxalato)borate (LiBOB) based electrolytes. The LiBOB-based electrolyte with DES shows high oxidation potentials, and good conductivities.

Technology Process of Diethyl sulfite

There total 32 articles about Diethyl sulfite which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:
