Kupu Whakataki

Ko te konutai borohydride he pūhui pararopi. He paura totoka he ngawari te whakarewa ki te wai, ka puta he otinga kawakore.

 

He kaha te whakaheke o te konutai borohydride, ka taea te tauhohe me te maha o nga pūhui waro. Kei te whakamahia whānuitia i roto i te whakahiato pararopi me te maha o nga wa e whakamahia ana hei kaihoko hauwai. Ka taea e te konutai borohydride te whakaheke i te aldehydes, te ketones, te esters, me etahi atu ki nga waipiro e rite ana, ka taea hoki te whakaheke i te waikawa ki te waipiro. Ka taea hoki te whakamahi konutai borohydride i roto i te decarboxylation, dehalogenation, denitrification me etahi atu tauhohenga.

 

Ko te whakaritenga o te konutai borohydride te tikanga ka whiwhi i te hohenga o te borane me te konutai konutai. Tuatahi, ka tauhohehia te konutai konutai ki te hauwai hei whakarite i te konutai hydride, katahi ka tauhohe ki te trimethylamine borane (triethylaminoborane ranei) i roto i te whakarewa etera kia whiwhi ai te konutai borohydride.

 

Ko te konutai borohydride he maatete whakaheke kaha ka tere te urupare ki te makuku me te hāora i te rangi ki te tuku hauwai. Kia tere te hiri o te ipu, kia maroke i te wa e mahi ana. Ko te konutai borohydride he ngawari te urupare ki nga waikawa ki te tuku hau hauwai, me karohia te whakapiri ki nga waikawa. He paitini ano te konutai borohydride, me tupato kia kore e pangia e te hau, te pa ki te kiri ranei. I te wa e whakamahi ana i te konutai borohydride, kakahuria nga karapu whakamarumaru me nga karaehe, me te whakarite kia whakahaerehia te mahi i roto i te taiao pai.
