868-18-8 Usage
Description
Sodium tartrate Na2C4H4O6) is used as an emulsifier and a binding agent in food products such as jellies, margarine, and sausage casings. As a food additive, it is known by the E number E335. Because its crystal structure captures a very precise amount of water, it is also a common primary standard for Karl Fischer titration, a common technique to assay water content.
Chemical Properties
White crystals or granules. Soluble in water; insoluble
in alcohol.
Uses
Different sources of media describe the Uses of 868-18-8 differently. You can refer to the following data:
1. Sodium Tartrate is a sequestrant and stabilizer that is the disodium
salt of l(+)—tartaric acid. it is soluble in water. it functions as a
sequestrant and stabilizer in meat products and sausage casings. it is
also termed disodium tartrate.
2. Reagent, food additive, as sequestrant and sta-
bilizer.
3. Sodium L-(+)-Tartrate is a food additive, use as an emulsifier and binding agent in food products.
Definition
ChEBI: The organic sodium salt that is the disodium salt of L-tartaric acid.
Flammability and Explosibility
Notclassified
Check Digit Verification of cas no
The CAS Registry Mumber 868-18-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,6 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 868-18:
(5*8)+(4*6)+(3*8)+(2*1)+(1*8)=98
98 % 10 = 8
So 868-18-8 is a valid CAS Registry Number.

Liquid-liquid equilibrium phase diagrams of polyethyleneglycol + sodium tartrate + water two-phase systems
Malpiedi, Luciana Pellegrini,Fernandez, Cintia,Pico, Guillermo,Nerli, Bibiana
, p. 1175 - 1178 (2008)
The phase diagrams of aqueous two-phase systems formed by water, sodium tartrate, and polyethyleneglycol of different molecular weights (600, 1000, 2000, 4000, 6000, and 8000) were determined at 298 K. The effect of NaCl on the liquid-liquid equilibrium was also analyzed. The binodal curves were satisfactorily described using a four-parameter sigmoidal equation. The tie lines were determined by combining a colorimetric method and density measurements. The reliability of the measured tie line compositions was ascertained by the Othmer-Tobias and Bancroft correlation equations.
