Pyrophosphoric acid CAS 2466-09-3
ʻO ka waika Pyrophosphoric he ʻano aniani ʻaʻole waihoʻoluʻu a i ʻole ka wai viscous kala ʻole e hana i nā kristal ma hope o ka mālama lōʻihi ʻana a he aniani kala ʻole. Pyrophosphate iions i ikaika coordination waiwai, a excessive P2O74- hiki ke hoʻoheheʻe insoluble paʻakai pyrophosphate (Cu2+, Ag+, Zn2+, Mg2+, Ca2+, Sn2+, etc.) e hana i nā ion hui, e like me [Cu (P2O7) 2] 6-, [ Sn (P2O7) 2] 6-, a pēlā aku. Hoʻohana mau ʻia ʻo ia ma ke ʻano he catalyst ma ka ʻoihana e hana i nā esters phosphate organik, etc.

Hoʻohana ʻia ka waika Pyrophoric ma ke ʻano he catalyst, masking agent, metala hoʻomaʻemaʻe a me ka stabilizer no nā peroxides organik. Hoʻohana ʻia ia e hoʻoponopono i ka waiwai Ph o ka hopena electroplating i ke kaʻina hana electroplating keleawe. Pyrophoric acid ka mea mālama wai, hoʻomaikaʻi maikaʻi, pH regulator, metala chelating agent.
Hoʻopili pinepine ʻia i ka 25kg / pahu, a hiki ke hana ʻia i ka pōʻai maʻamau.
