Used in the Production of Potassium Oxalate:
Potassium trihydrogen dioxalate is also used in the production of potassium oxalate, which can be found in the leaves and roots of certain plants and has various applications in different industries.
Preparation
Potassium oxalate can be preparaed by heating potassium formate at 360°C:2HCOOK →K2C2O4+ H2The salt is obtained as its monohydrate by neutralization of oxalic acid with a dilute aqueous solution of potassium hydroxide followed by crystallization:H2C2O4+ 2KOH →K2C2O4+ 2H2O.
Flammability and Explosibility
Nonflammable
Purification Methods
Crystallise it from water below 50o. Dry it below 60o at 760mm. [See potassium oxalate above, Beilstein 2 IV 1823.]
Check Digit Verification of cas no
The CAS Registry Mumber 127-96-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 7 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 127-96:
(5*1)+(4*2)+(3*7)+(2*9)+(1*6)=58
58 % 10 = 8
So 127-96-8 is a valid CAS Registry Number.
