868-18-8 Usage
Description
Sodium tartrate (Na2C4H4O6) is the disodium salt of L-tartaric acid, a white crystalline or granular organic compound that is soluble in water and insoluble in alcohol. It is known for its precise water capture in its crystal structure, making it a common primary standard for Karl Fischer titration, a technique used to determine water content.
Uses
Used in Food Industry:
Sodium tartrate is used as a food additive, specifically as an emulsifier and binding agent in food products such as jellies, margarine, and sausage casings. It helps to improve the texture and stability of these products. As a food additive, it is identified by the E number E335.
Used in Meat Products and Sausage Casings:
Sodium tartrate functions as a sequestrant and stabilizer in meat products and sausage casings, enhancing their quality and shelf life.
Used in Chemical Industry:
Sodium tartrate is utilized as a reagent and serves as a sequestrant and stabilizer in various chemical applications.
Used in Pharmaceutical Industry:
Due to its precise water capture in its crystal structure, sodium tartrate is a common primary standard for Karl Fischer titration, a technique widely used in the pharmaceutical industry to assay water content in active pharmaceutical ingredients and final products.
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.
