white crystalline powder or colourless crystals | [Uses]
A method of utilizing a solution of Oxalic acid potassium salt, dihydrate 99 % to react with calcium in the dentinal fluid forming an insoluble white precipitate of calcium oxalate which occludes the dentinal tubules causing decreased sensitivity, permeability and acid penetration of the dentin. | [Synthesis]
A method of producing potassium tetraoxalate by fermentation of Aspergillus niger, the method comprising the steps of:
a. Isolation and purification of Aspergillus niger: stem segments of wrinkled edge stone fir plant were selected, rinsed by r | [Purification Methods]
Crystallise it from water below 50o. Dry it below 60o at 760mm. [See potassium oxalate above, Beilstein 2 IV 1823.] |
