623-81-4 Usage

Chemical Properties

clear colorless solution

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.

General Description

This product has been enhanced for energy efficiency.

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.

PROCESS FOR PRODUCING CYCLOPROPANE MONOACETAL DERIVATIVE AND INTERMEDIATE THEREFOR

-

Page/Page column 10, (2008/06/13)

A method of industrially advantageously producing a cyclopropane monoacetal derivative represented by the formula (III) conveniently and also in a fewer steps by reacting a halogenated unsaturated carbonyl compound represented by the formula (II) with an alcoholate. wherein each symbol is as defined in the specification.

Reactions of 4-chloromethyl-1,3,2-dioxathiolane 2-oxides with sodium phenoxide. A reinvestigation

Bredikhina, Z. A.,Pashagin, A. V.,Bredikhin, A. A.

, p. 1753 - 1756 (2007/10/03)

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.
