General description

We are committed to bringing you Greener Alternative Products, which belongs to one of the four categories of greener alternatives. This product has been enhanced for energy efficency. Click here for more information.
Barium hydroxide crystalizes as octahydrate. At 100°C, it transforms into barium hydroxide monohydrate, which produces barium oxide and water. It serves as a precursor in the synthesis of a compound containing barium. It is also employed in the titration of weak acids. Furthermore, the hydrolysis of ester and nitriles uses barium hydroxide octahydrate as a powerful base

Application

催化磷酸丝氨酸残基的 β-消去反应。
Barium hydroxide octahydrate is used as a catalyst for the synthesis of methyl ester from rubber seed oil For thermal storage, barium hydroxide octahydrate is an important phase change material with a low melting point. It has a large heat capacity, as well as supercooling and phase separation phenomena during the cooling process Additionally, barium hydroxide octahydrate was used to produce a sodium gold sulfite solution, which was later used for electroless plating of thin gold films directly onto silicon nitride thin films and into micropores
