Fa'aoga ma le fa'aogaina o le Piperazine-N,N'-bis(2-hydroxypropanesulfonic acid) disodium masima

Fa'aoga: Piperazine-N,N-bis(2-hydroxyethanesulfonic acid) sodium masima o lo'o i ai se vaega o le sulfonic acid i luga o le piperazine mama, vaila'au ma uiga fa'avae e fuafua ai le piperazine-N,N-bis(2-hydroxyethanesulfonic acid) acid) masima sodium atoatoa. dissociates i le vai, lea e mafua i lona osmotic taʻiala taʻiala, lea e aoga e faʻatupu ai le maualuga o le mamafa osmotic.I le taimi nei, pe a faʻaaogaina le piperazine-N,N-bis(2-hydroxyethanesulfonic acid) sodium masima e fai ma solute osmotic Chemicalbook diassorb solute, e mafai ona maua le faʻasalalau solute laʻititi i tua ona o lona faʻatulagaga tolu-dimensional.O nei tulaga lelei e faʻaalia ai le faʻaogaina ma le lelei o le piperazine-N,N-bis(2-hydroxyethanesulfonic acid) sodium salt e avea o se faʻamama osmosis i luma.O le mea taua, o le piperazine-N,N-bis(2-hydroxyethanesulfonic acid) sodium salts e tosina mai solute a'o fa'aosoina maualuga i luma osmotic vai felafoa'i ma fa'atauva'a fa'aliliu solute salalau, fa'amaonia lo latou Fa'aoga ma Avanoa.

Sauniuniga: Piperazine-N,N-bis(2-hydroxyethanesulfonic acid) sodium masima (P-2SO3-2Na) na saunia e pei ona taua i lalo: Piperazine (2.15 g, 25 mmol) na faʻamavaeina i le 20 mL o le vai DI.Ona sosoo ai lea ma le ClCH2CH2SO3Na (9.23 g, 50 mmol) ma le NaOH Chemicalbook (1.60 g, 50 mmol) fa'aopoopo fa'asolosolo.O le vaifofo na maua na faʻaauau pea ona faʻafefe i le 40 ° C i le po.Sa faia se fofo manino.O le oloa na maua e ala i timuga mai le ethanol malulu ma faʻamamaina mai le H2O/EtOH.O le paʻepaʻe paʻepaʻe piperazine-N, N-bis (2-hydroxyethanesulfonic acid) sodium masima na aoina ina ua uma ona faʻamago (> 99% fua).
