623-81-4 Usage
Description
Diethyl sulfite (DES) is a clear colorless solution that has been enhanced for energy efficiency. It is a chemical compound with unique properties that make it suitable for various applications, particularly in the field of energy storage and battery technology.
Uses
Used in Energy Storage Industry:
Diethyl sulfite is used as a film-forming and high-temperature additive for electrolytes in lithium-ion batteries. Its application reason is to improve the decomposition resistance of the electrolyte, which contributes to the overall performance and longevity of the battery.
Diethyl sulfite is also used as a solvent for lithium bis(oxalato)borate (LiBOB) based electrolytes. The LiBOB-based electrolyte with DES demonstrates high oxidation potentials and good conductivities, making it a valuable component in the development of advanced battery systems for various energy storage applications.
Check Digit Verification of cas no
The CAS Registry Mumber 623-81-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 623-81:
(5*6)+(4*2)+(3*3)+(2*8)+(1*1)=64
64 % 10 = 4
So 623-81-4 is a valid CAS Registry Number.

A novel, high-yielding method for sulfation of alcohols has been developed, proceeding via sulfite- and sulfate diester intermediates. Sulfite diesters serve as versatile sulfate monoester precursors, allowing for transformations that are difficult or impossible with the latter compounds.
Reactions of 4-chloromethyl-1,3,2-dioxathiolane 2-oxides with sodium phenoxide. A reinvestigation

The reactions of 4-chloromethyl-1,3,2-dioxathiolane 2-oxides with PhONa in EtOH are accompanied by ring opening under the action of the ethoxide ion rather than leading to a rearrangement of the starting molecule as has been assumed previously. Under conditions precluding competition with other nucleophiles, the phenoxide anion smoothly replaces the chlorine atom in chloromethyl-substituted cyclic sulfites.
