Useful:

• Uses: The monohydrate , CaC2O4?H2O, mol wt 128.10, is of importance principally as an intermediate in oxalic acid manufacture and in analytical chemistry; it is the form in which calcium is frequently quantitatively isolated. Calcium oxalate monohydrate is used as a precursor in the production of oxalic acid, organic oxalates, ceramic glazes, and for rare-earth-metal separation process.

Technology Process of Calcium oxalate monohydrate

There total 21 articles about Calcium oxalate monohydrate 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:
