Useful:

• Uses: Potassium oxalate is a white crystal or powder made by neutralizing oxalic acid with potassium carbonate. It is soluble in water 1:3 but not in alcohol. Potassium oxalate was used as an early developer for gelatin plates but is best known as the developer for platinum prints. Cleaning and bleaching straw, removing stains in photography; in vitro blood anticoagulant; also in analytical chemistry.

Technology Process of Potassium oxalate

There total 91 articles about Potassium oxalate which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 93.0%

potassium formate (590-29-4) → potassium oxalate (583-52-8) + potassium carbonate (584-08-7)

Guidance literature:

potassium hydroxide; In solid; byproducts: H2; 330 °C; with KOH (1:0.05) in N2 atmosphere, the heating rate 6 deg/min;

DOI:10.1007/BF01913982

Reference yield: 80.0%

potassium hydroxide → potassium oxalate (583-52-8)

Guidance literature:

With sawdust; In not given; oxidation at 240-250°C through 1-15 hours by air admission;

Reference yield: 72.0%

Hg(b),K(2) (X%) + carbon dioxide (124-38-9,18923-20-1) → potassium oxalate (583-52-8)

Guidance literature:

In neat (no solvent); byproducts: K2CO3; 200°C;;

upstream raw materials:

methylammonium carbonate

potassium fluoride

oxalic acid

potassium carbonate

Downstream raw materials:

3-methyl-butan-2-one

2-chloro-3-methyl-2-butene

propionic acid
