• Description: Barium oxalate, a Barium salt of oxalic acid, is a white odourless powder that is sometimes used as a green pyrotechnic colorant generally in specialized pyrotechnic compositions containing magnesium. Though largely stable, it can be reactive with strong acids. A mild skin irritant, the substance is considered toxic when ingested, causing nausea, vomiting, renal failure and injury to the gastrointestinal tract. Its molecular structure is written as C2BaO4. The raw materials that are required to prepare Barium oxalate are oxalic acid, Barium hydroxide octahydrate, and Barium hydroxide. It can also be prepared alternatively by using an oxalic acid solution and a Barium chloride solution, with the reaction as follows: BaCl2 + (COOH)2 > BaC2O4 + HCl It is different from most pyrotechnic colorants in that it is a reducing agent, and not an oxidizing agent. It is extremely insoluble in water and converts to the oxide form when heated.
• Uses: Analytical reagent, pyrotechnics. Barium oxalate, Puratronic isused as a green pyrotechnic colorant?generally in specialized?pyrotechnic compositions?containing?magnesium.

Technology Process of Barium oxalate

There total 42 articles about Barium 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: 52.04%

Hg(b),Ba(0.298) (W%) + carbon dioxide (124-38-9,18923-20-1) → barium oxalate (516-02-9)

Guidance literature:

In neat (no solvent); treatment of Ba amalgam with CO2 at ambient temp., complete exclusion of O2 and atmospheric moisture;;

Reference yield: 52.0%

carbon dioxide (124-38-9,18923-20-1) → barium oxalate (516-02-9)

Guidance literature:

With Ba-amalgam;

Reference yield:

BaO*CO2=BaCO3 + 3H(1+)*{IrCl4(C2O4)}(3-)*99H2O=H3{IrCl4(C2O4)}*99H2O → iridium (III) chloride (10025-83-9) + barium oxalate (516-02-9)
