Kupu Whakataki

Ko te O-bromobenzoyl chloride e mohiotia ana ko te 2-bromobenzoyl chloride. E whai ake nei he kupu whakataki mo tona ahuatanga, te whakamahinga, nga tikanga whakangao me nga korero haumaru:

 

Kounga:

- Te ahua: Ko te O-bromobenzoyl chloride he wai kore tae, he wai kowhai ranei.

- Wairewa: He iti te wairewa ki te wai, he whakarewa ake i roto i nga whakarewa waro penei i te etera, te methanol me te methylene chloride.

- Tauhohenga: Ko te O-bromobenzoyl chloride he pūhui acyl chloride e kaha ana ki nga tauhohenga whakakapi acyl.

 

Whakamahia:

- Ko te O-bromobenzoyl chloride kei te whakamahia i roto i nga tauhohenga acyl chlorination i roto i te whakahiato waro mo te whakauru i nga roopu acyl.

- I roto i etahi whakahiato pararopi, ka taea te whakamahi hei kaikawe vulcanizing, he kaihoko whakaheke, he kaihoko oxidizing ranei.

 

Tikanga:

Ko te O-bromobenzoyl chloride te nuinga o te wa ka mahia e te tauhohenga bromination o te o-bromobenzoyl chloride. Ko nga taahiraa motuhake e whai ake nei:

Tuatahi, ka tauhohehia te o-bromobenzophenone me te bromine i raro i nga tikanga waikawa hei whakaputa i te waikawa o-bromobenzoic.

Ka tauhohehia te waikawa o-bromobenzoic ki te phosphoryl chloride (POCl₃) ki te whakaputa o-bromobenzoyl chloride.

 

Mōhiohio Haumaru:

- Ko te O-bromobenzoyl chloride he mea whakapataritari, me karo i te pa ki te kiri, ki nga kanohi me nga waahanga manawa.

- Kia mau i nga karapu whakamarumaru, motiiti me nga kakahu whakamarumaru ina whakamahi.

- A ape i te pa atu ki nga kaikawe waikura kaha, ki nga kawakore kaha, ka puta he tauhohenga kino.

- Me tuku tika nga para me nga whakarewa i te wa e mahi ana, me mahi nga tikanga haumaru taiwhanga.
