Kupu Whakataki

Ko te konupora borohydride he pūhui pararopi. Ko ona ahuatanga e whai ake nei:

 

1. Te ahua: Ko te konupora borohydride he paura tioata ma, he kirikiri ranei.

 

3. Wairewa: Ko te konupora borohydride te wairewa i roto i te wai, me te āta wairewa ki te wai hei whakaputa i te hauwai me te pāhare pāhare wai.

 

4. Te taumahatanga: Ko te kiato o te konupora borohydride he 1.1 g/cm³.

 

5. Pumautanga: I raro i nga tikanga noa, ko te borohydride pāhare pāporo he āhua pūmau, engari ka pirau i te aroaro o te pāmahana teitei, te haumākū nui me te kaha hāora.

 

Ko nga whakamahinga matua o te borohydride pāhare pāporo ko:

 

1. Te puna hauwai: Ka taea te whakamahi i te konupora borohydride hei reagent mo te whakahiatotanga o te hauwai, ka puta ma te tauhohe ki te wai.

 

2. He matū whakaheke matū: Ka taea e te pāhare pāporo borohydride te whakaheke i ngā momo pūhui ki ngā pūhui waro e rite ana pēnei i te waipiro, te aldehydes, me te ketone.

 

3. Te maimoatanga mata whakarewa: Ka taea te whakamahi konupora borohydride mo te maimoatanga electrolytic hydrogenation o nga papa whakarewa hei whakaiti i te waikura mata.

 

Ko nga tikanga whakarite o te borohydride pāhare pāporo te nuinga ko te tikanga whakaheke tika, te tikanga antiborate me te tikanga whakaheke paura konumohe. I roto ia ratou, ko te tikanga e whakamahia nuitia ana ka riro mai i te tauhohenga o te konutai phenylborate me te hauwai i raro i te mahi a te whakakōkī.

 

Ko nga korero haumaru o te pāhare pāporo borohydride e whai ake nei:

 

1. He kaha te whakaheke o te konupora borohydride, ka puta te hauwai ina tauhohe ki te wai me te waikawa, na reira me whakahaere ki tetahi waahi whai hau.

 

2. A ape i te pa ki te kiri, ki nga kanohi, me te ara manawa ki te aukati i te riri me te whara.

 

3. I te wa e penapena ana me te whakamahi i te borohydride pāhare pāporo, me tupato kia kore e pa ki nga waikura me etahi atu matū hei aukati i te ahi, te pahūtanga ranei.

 

4. Kaua e whakaranua te borohydride pāhare pāporo me ngā matū waikawa hei karo i te hanga o ngā hau mōrearea.

 

5. I te tukunga o te para borohydride pāhare pāporo, me whai i nga ture taiao me te haumaru.
