Kupu Whakataki

Ko Diethyl zinc he pūhui organozinc. He wai kore tae, he mura ahi, he haunga kino. E whai ake nei he kupu whakataki mo nga rawa, nga whakamahinga, nga tikanga whakarite me nga korero haumaru o te diethylzinc:

 

Kounga:

Te ahua: Te wai kore tae me te haunga

Kiato: approx. 1.184 g/cm³

Wairewa: whakarewa i roto i nga whakarewa pararopi penei i te waihano me te benzene

 

Whakamahia:

Ko te konutea Diethyl he reagent nui i roto i te whakahiato waro, ka whakamahia ki te whakarite i nga whakakorikori.

Ka taea hoki te whakamahi hei kaikawe me te whakaheke i nga kaihoko mo nga olefins.

 

Tikanga:

Ma te tauhohe i te paura konutea ki te ethyl chloride, ka hangaia te konutea diethyl.

Me whakahaere te mahi whakarite i raro i te maru o te hau koretake (hei tauira, te hauota) me te iti o te mahana kia pai ai te haumaru me te hua nui o te tauhohenga.

 

Mōhiohio Haumaru:

He tino muramura te konutea Diethyl me te pa atu ki te puna mura ka puta he ahi, he pahū ranei. Me mahi nga mahi aukati ahi me te pahūtanga i te wa e rokiroki ana me te whakamahi.

Mau taputapu whakamarumaru e tika ana penei i nga kakahu whakamarumaru matū, karaehe whakamarumaru, me nga karapu ina whakamahi.

A ape i te pa atu ki nga waikura kaha me nga waikawa hei aukati i nga tauhohenga tutu.

Me whakahaere te Diethylzinc i roto i te waahi pai-hau hei whakaiti i te kohinga hau kino.

Whakaorangia kia hiritia, ka waiho ki tetahi wahi maroke, hauhautanga kia kore ai e tau nga ahuatanga.
