Te Whakamahi me te Whakakotahitanga o Piperazine-N,N'-bis(2-hydroxypropanesulfonic acid) tote disodium

Taupānga: Piperazine-N,N-bis(2-hydroxyethanesulfonic acid) te tote konutai he roopu waikawa sulfonic i runga i te mowhiti piperazine, matū me nga ahuatanga hanganga ka whakatau i te piperazine-N,N-bis(2-hydroxyethanesulfonic acid) waikawa) te tote konutai. ka wehewehe i roto i te wai, e kiia ana na tana kaupapa taraiwa osmotic, he painga ki te whakaputa pehanga osmotic teitei.I tenei wa, ka whakamahia te tote konutai piperazine-N,N-bis(2-hydroxyethanesulfonic acid) hei tote osmotic Chemicalbook diassorb whakamua, ka taea te whakararu i te whakamaaramatanga whakamuri iti i runga i tana whirihoranga ahu-toru.Ko enei painga e whakaatu ana i te whaihua me te pai o te mahi o te piperazine-N,N-bis(2-hydroxyethanesulfonic acid) te tote konutai hei whakamarumaru osmosis whakamua.Ko te mea nui, ko te piperazine-N,N-bis(2-hydroxyethanesulfonic acid) te tote konutai e kukume ana i nga wairewa i te wa e whakaputa ana i nga rerenga wai osmotic teitei me te whakamaaramatanga o te wairewa whakamuri whakamuri, e whakamana ana i te Whakamahinga me te Pumanawa.

Te Whakaritenga: Piperazine-N,N-bis(2-hydroxyethanesulfonic acid) te tote konutai (P-2SO3-2Na) i whakaritea penei: Piperazine (2.15 g, 25 mmol) i rewa ki te 20 mL o te wai DI.Kātahi ka tāpirihia te ClCH2CH2SO3Na (9.23 g, 50 mmol) me te NaOH Chemicalbook (1.60 g, 50 mmol).Ko te otinga o te otinga ka whakaoho tonu i te 40°C mo te po.I hanga he otinga marama.I whiwhi te hua i te rerenga mai i te waiwaro makariri me te purea mai i te H2O/EtOH.Ko te paura ma te piperazine-N,N-bis(2-hydroxyethanesulfonic acid) te tote konutai i kohia i muri i te whakamaroke (> 99% hua).
