Ka hoʻohana a me ka Synthesis o Piperazine-N,N'-bis(2-hydroxypropanesulfonic acid) disodium paʻakai

Noi: Piperazine-N,N-bis(2-hydroxyethanesulfonic acid) sodium paʻakai he sulfonic acid pūʻulu ma ke apo piperazine, kemika a me nā ʻano hana e hoʻoholo ai i ka piperazine-N,N-bis(2-hydroxyethanesulfonic acid) acid) paʻakai paʻakai loa. dissociates i loko o ka wai, ka mea i hoʻoili ʻia i kāna kumu hoʻokele osmotic, he mea pono e hoʻoulu i ke kaomi osmotic kiʻekiʻe.I kēia manawa, ke hoʻohana ʻia ka paʻakai sodium piperazine-N,N-bis(2-hydroxyethanesulfonic acid) ma ke ʻano he osmotic Chemicalbook diassorb solute, hiki ke loaʻa ka liʻiliʻi hoʻohuli solute diffusion ma muli o kāna hoʻonohonoho hoʻonohonoho ʻekolu.Hōʻike kēia mau mea maikaʻi i ka hoʻohana ʻana a me ka hana maikaʻi o ka paʻakai paʻakai paʻakai piperazine-N,N-bis(2-hydroxyethanesulfonic acid) ma ke ʻano he mua osmosis desalter.ʻO ke koʻikoʻi, ʻo ka piperazine-N, N-bis(2-hydroxyethanesulfonic acid) ka paʻakai sodium e huki i nā solutes i ka wā e hana ana i nā kahe wai osmotic kiʻekiʻe me ka negligible reverse solute diffusion, e hōʻoia ana i kā lākou Hoʻohana a me ka hiki.

Hoʻomākaukau: Piperazine-N, N-bis (2-hydroxyethanesulfonic acid) sodium paʻakai (P-2SO3-2Na) i hoʻomākaukauʻia penei: Piperazine (2.15 g, 25 mmol) i hoʻoheheʻeʻia i 20 mL o ka wai DI.A laila ua hoʻohui pū ʻia ʻo ClCH2CH2SO3Na (9.23 g, 50 mmol) a me NaOH Chemicalbook (1.60 g, 50 mmol).Hoʻoulu mau ʻia ka hopena hopena ma 40 ° C i ka pō.Ua hoʻokumu ʻia kahi haʻina maopopo.Loaʻa ka huahana ma ka ua mai ka ethanol anu a hoʻomaʻemaʻe ʻia mai H2O/EtOH.ʻO ka piperazine-N,N-bis (2-hydroxyethanesulfonic acid) ka paʻakai sodium i hōʻiliʻili ʻia ma hope o ka maloʻo ʻana (> 99% hua).
