BES CAS:10191-18-1 Utu Kaihanga

Ko te waikawa N,N-Bis(hydroxyethyl)-2-aminoethanesulfonic, e mōhiotia ana ko te BES, ko te waikawa N,N-Bis(2-hydroxyethyl)aminoethanesulfonic rānei, he matū e whakamahia whānuitia ana hei ārai i roto i ngā mahi pūtaiao me ngā mahi ahumahi.

He matū zwitterionic te BES, arā, he rua ngā utu pai, rua hoki ngā utu kino i roto i tōna hanganga. Mā tēnei āhuatanga ka taea e ia te pupuri i te pH pumau i roto i ngā otinga.

Ko te uara pKa o te BES he tata ki te 7.4, ā, he tino whai hua mō te pupuri i ngā taumata pH ā-tinana. He maha ngā wā ka whakamahia i roto i ngā whakamātautau koiora me te matū koiora, pērā i te purenga pūmua, ngā tauhohenga whākōkī, me te ahurea pūtau, ina he mea nui te pupuri i tētahi pH motuhake.

Hei tāpiritanga, e whakamahia whānuitia ana te BES i roto i ngā tikanga hikohiko, nā te mea ka āwhina i te pupuri i te pH e tika ana mō te wehenga me te tātari i ngā koiora ngota kua utaina, pērā i ngā pūmua me ngā waikawa karihi.

Te Whakamahinga me te Pānga

Te Whakapūmau pH: He kaha te whakapūmau a te BES i te awhe pH i waenga i te 6.4 ki te 7.8. Ka āwhina i te pupuri i te pH pumau mā te whakahaere i te kukū o ngā katote hauwai i roto i te otinga. Nā tēnei ka tino whai hua i roto i ngā pūnaha whakamātautau koiora me te matū ina hiahiatia te pupuri i tētahi pH motuhake.

Te Whakapūmau Pūmua: E whakamahia whānuitia ana te BES i roto i ngā tikanga purenga me te rokiroki pūmua. Ka taea e ōna āhuatanga ārai te pupuri i te pH i roto i te awhe tino pai mō te pumau o te pūmua me te ārai i te denaturation, te degradation rānei o ngā pūmua.

Ngā Tauhohenga Whākōkī: He maha ngā wā ka whakamahia te BES hei ārai i ngā tauhohenga whākōkī. Ka āwhina i te pupuri i te pH tino pai mō te mahi whākōkī, kia pai ai te haere o te tauhohenga.

Te Ahurea Pūtau: Ka whakamahia te BES i roto i ngā mahi whakatipu pūtau, inā koa i roto i ngā momo pūtau o ngā kararehe. Ka āwhina i te pupuri i te pH o te puna tipu, he mea nui mō te oranga tonutanga o ngā pūtau me ngā mahi tino pai o ngā pūtau.

Te Whakapūngao Hiko: Ka whakamahia te BES hei matū ārai i roto i ngā tikanga whakapūngao hiko mō te wehenga me te tātari i ngā ngota koiora, tae atu ki ngā pūmua me ngā waikawa karihi. Mā tēnei ka whakarite kia puta te wehenga i roto i te awhe pH e hiahiatia ana, kia taea ai te tātari tika.
