2. Ngā āhuatanga matū: āhua pūmau i te otinga kūpapa.I muri i nga haora 8 o te 4% o te wairewa konutai wai, 50%~ 70% o te waiwai ka puta.Ka puta te hauwai i roto i nga kakano me te whakaputa waikawa aminocyl 4-meth.Na te tauhohenga o te turanga himipora, ka taea e ia te whakaputa ketone, sulfurboline ranei.

3. I roto i te noho o te kawakore whakakōkī, he pānga o te olefin, a ka puta he tauhohenga alkylated i te wahi tuatoru.He ngoikore te kawakore o te N-methylporide ka taea te whakaputa tote hydrochloride.I hanga he whakauru ki te tote whakarewa taimaha, penei i te whakamahana me te nickel bromide ki te 150 ℃, te whakaputa NIBR2(C5H9ON)3, me te rewa o te 105 ℃.

Mahi me te rokiroki:

1. Tikanga rokiroki

Whakaorangia i raro i te hau maroke maroke, kia hiritia te ipu, ka rongoa ki te waahi makariri me te maroke.

2. Nga mahi whakatupato

A ape i te whakaatu: Me whiwhi koe i nga aratohu motuhake i mua i te whakamahi.A ape i te pa ki te kiri me nga kanohi.A ape i te ngongo o te kohu me te auahi.Kaua e tata ki te puna o te ahi.-Kaore e kai paipa.Me whai tikanga hei aukati i te whakaemi pateko.

3. Whakatupato rokiroki

He waahi hauhautanga kei te rokiroki.Kia kati te ipu ka rongoa ki tetahi waahi maroke me te hau.Ko te ipu tuwhera me ata hiri me te pupuri i te turanga poutū kia kore ai e pakaru.Ko te whakakore i te whakamarumaru inflatable he tairongo ki te makuku.
