ʻO Cesium carbonate a i ʻole Cesium Carbonate maʻemaʻe 99.9% (metala kumu)

ʻO ka wehewehe pōkole:

ʻO Cesium Carbonate kahi kumu inorganic ikaika i hoʻohana nui ʻia i ka synthesis organik. He mea hoʻoheheʻe koho chemo no ka hōʻemi ʻana i nā aldehydes a me nā ketones i nā ʻona.

He aha ka Cesium Carbonate e hoʻohana ai?

ʻO ka Cesium carbonate kahi kumu maikaʻi e loaʻa ai nā noi hou aʻe i ka hoʻohui ʻana i ke kemika. Hoʻohana pū ʻia ʻo Cesium carbonate ma ke ʻano he catalyst no ka Aerobic oxidation o nā waiʻona mua. Ma ke ʻano he kumu waiwai no ka hana ʻana i nā pūhui cesium like ʻole, hoʻohana nui ʻia ʻo Cesium nitrate i ka catalyst, aniani kūikawā a me nā ceramics etc.
