Kupu Whakataki

Ko te 3-Bromopropyne, e mohiotia ana ko 1-bromo-2-propyne, he puhui waro. E whai ake nei he kupu whakataki poto mo ona rawa, ona whakamahinga, tikanga hanga me nga korero haumaru:

 

Kounga:

- He iti ake te kiato, me te 1.31 g/mL te uara.

- 3-He hongi kawa a Bropropyne.

- Ka taea te whakarewa ki etahi whakarewa pararopi penei i te waihano me te etera.

 

Whakamahia:

- Ko te 3-Broproyne te nuinga o te whakamahi hei reagent i roto i nga tauhohenga whakahiato waro, hei tauira ka taea e ia te uru atu ki nga tauhohenga honohono-whakawhitinga whakarewa mo te whakahiatotanga o nga pūhui waro.

- Ka taea hoki te whakamahi hei rauemi timatanga mo te alkynes, hei tauira mo te whakahiato o nga alkynes me etahi atu alkynes mahi.

 

Tikanga:

- Ka taea te whiwhi 3-Bromopropyne ma te tauhohenga o te bromoacetylene me te ethyl chloride i raro i nga tikanga kawakore.

- Ka mahia tenei ma te whakaranu i te bromoacetylene me te ethyl chloride me te taapiri i te nui o te kawakore (pērā i te konutai warowaihā, te konutai warokawa ranei).

- I te mutunga o te tauhohenga, ka whiwhi te 3-bromopropynne parakore ma te whakamaarama me te purenga.

 

Mōhiohio Haumaru:

- Ko te 3-Bropropyne he matū paitini me te whakapataritari e hiahia ana kia mau nga taputapu tiaki whaiaro (PPE) i te wa e mahi ana.

- Me karo i te pa atu ki nga waikura, nga kawakore kaha, me nga waikawa kaha kia kore ai nga tauhohenga kino.

- Whakaritea nga tikanga whakahaere haumaru e tika ana i te wa e whakamahia ana me te rokiroki.

- I te wa e whakahaere ana i te 3-bromopropyne, me whakarite kia pai te hau me te karo i te tango i ona kohu, ka pa ranei ki te kiri me nga kanohi.
