바륨포스피네이트 C화학적 특성, 용도, 생산
화학적 성질
monoclinic platelets; can be prepared by reacting white phosphorus and barium hydroxide; used in nickel plating; anhydrous material, Ba(H2PO2)2, is a white, odorless, crystal(s) powder(s) [MER06] [HAW93]생산 방법
Barium hypophosphite and PH3 are produced in the reaction of white phosphorus with Ba(OH)3. A solution of 120 g of crystalline Ba(OH) in 1200 ml of water is heated for about four hours with 30 g of white P in a round bottom flask. The flask is provided with a long glass tube extending to the stack of the exhaust hood to conduct away the spontaneously igniting phosphine mixture. When the P is completely dissolved, CO2 is introduced to precipitate the excess Ba(OH)3. The precipitate is filtered off and washed with hot water. The solution and the wash water are combined and evaporated to half the original volume, refiltered, and evaporated until crystallization begins. Some alcohol is then added, and the mixture is left to cool. The resulting crystals are suction-filtered, and the mother liquor is again evaporated until crystallization takes place. The accumulated salts are combined and recrystallized from hot water to produce barium phosphinate. The yield is 40-60 g.Purification Methods
It precipitates from aqueous solution (3mL/g) on adding EtOH. Its solubility in H2O is 28.6% at 17o and 33.3% at 100o. [Klement in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 557 1963.]바륨포스피네이트 준비 용품 및 원자재
