Kupu Whakataki

Ko te 2, 3-Dimethylpyrazine he pūhui waro. E whai ake nei he kupu whakataki mo etahi o ona taonga, ona whakamahinga, tikanga hanga me nga korero haumaru:

Kounga:

Ko te 2, 3-Dimethylpyrazine he toka kowhai ki te kowhai. He haunga o te acetone, ethers ranei, ka taea te rewa i roto i nga waipiro me nga whakarewa ether.

Whakamahia:

2, 3-Dimethylpyrazine te nuinga whakamahia rite te rauemi timata mo te kōtuitanga organic. Ka taea te whakamahi hei whakakorikori mo te esterification, carboxylation me te enolation i raro i nga tikanga alkaline.

Tikanga:

Ka taea te whakarite 2, 3-dimethylpyrazine ma te whakakapi SN2 o te ethyl iododide me te ethyl bromide me te 2-aminopyrazine. Ko nga tikanga tauhohenga ka mahia ki te aroaro o te reo kawakore, penei i te konutai ethoxide. I muri i te tauhohenga, ka whiwhi te hua i whäia e te whakatioatanga, te tangohanga ranei.

Mōhiohio Haumaru:

2, 3-Dimethylpyrazine he iti te paitini i raro i nga tikanga whakamahi noa. I te mea he matū, ka pa ki te kiri, ki nga kanohi, me te ara manawa ka pa te riri. Me whai i nga tikanga haumaru taiwhanga taiwhanga penei i te mau karapu taiwhanga whakamarumaru, motiiti, me nga taputapu whakamarumaru manawa ka whakamahia. Mena ka pa mai, ka werohia ranei, ka horoi, ka tango wawe ranei i te waahi kua pa, ka rapu tohutohu hauora.
