921-53-9 Usage

Description

Potassium tartrate, dipotassium tartrate or argol has formula K2C4H4O6. It is the potassium salt of tartaric acid. It is often confused with potassium bitartrate, also known as cream of tartar. As a food additive, it shares the E number E336 with potassium bitartrate.

Chemical Properties

white crystalline powder

Uses

Different sources of media describe the Uses of 921-53-9 differently. You can refer to the following data:
1. Manufacture of potassium salts, medicine (cathartic), lab reagent.
2. Potassium tartrate is the acid potassium salt of tartaric acid occurring as crystals or powder. It is relatively poorly soluble having a solubility in 100 ml of water at 0.8 g at 25°c and 6.1 g at 100°c. A 1% solution at 30°c has a ph of 3.4. Chemical names are potassium acid tartrate, potassium hydrogen tartrate, and potassium bitartrate. It functions to complex with heavy metal ions and to regulate ph; it can have a gentle laxative action if given at adequate levels. The acidulant is used in chemical leavening to release carbon dioxide which produces the loaf volume. It has limited reactivity in the cold so when used in reduced-temperature batters it has little gas evolution during the initial mixing. At room temperatures, it has a relatively fast reaction rate. It functions as a taste regulator in sugar icing and in controlled crystallization of toffees and fondants by the regulated inversion of sucrose. It is used in baked goods, crackers, candy, and puddings.

Definition

ChEBI: The potassium salt of L-tartaric acid.

Preparation

Potassium tartrate is produced by the reaction of tartaric acid with potassium sodium tartrate (rochelle salt), and potassium sulfate, followed by filtration, purification, precipitation and drying.

Flammability and Explosibility

Notclassified

Check Digit Verification of cas no

The CAS Registry Mumber 921-53-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,2 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 921-53:
(5*9)+(4*2)+(3*1)+(2*5)+(1*3)=69
69 % 10 = 9
So 921-53-9 is a valid CAS Registry Number.
