METHOD FOR PRODUCING BARIUM TITANYL OXALATE AND METHOD FOR PRODUCING BARIUM TITANATE

WIPO Patent Application WO/2022/107695

A1

A method for producing barium titanyl oxalate, wherein barium titanyl oxalate is produced by mixing and reacting a solution containing oxalic acid (solution A) and a solution containing a titanium source and a barium source (solution B) with each other, said method being characterized by: separately supplying the solution A and the solution B to one end of a reaction liquid channel, mixing the solution A and the solution B with each other within the reaction liquid channel, discharging the reaction liquid from the other end of the reaction liquid channel, and subsequently performing solid-liquid separation of the reaction liquid; setting the residence time of the reaction liquid within the reaction liquid channel to 30 seconds or less; or separately supplying the solution A and the solution B to one end of the reaction liquid channel, mixing the solution A and the solution B with each other at the one end of the reaction liquid channel, moving the reaction liquid to the other end of the reaction liquid channel, while generating a vortex flow in the reaction liquid, discharging the reaction liquid from the other end of the reaction liquid channel, and subsequently performing solid-liquid separation of the reaction liquid.
