Kupu Whakataki

Ko te 2-Methoxy-4-nitroaniline he pūhui waro. E whai ake nei he kupu whakataki mo ona rawa, ona whakamahinga, tikanga hanga me nga korero haumaru:

 

Kounga:

- Te ahua: Ko te 2-Methoxy-4-nitroaniline he karaihe kowhai, he paura karaihe ranei.

- Wairewa: He paku te whakarewa i roto i te waiwaro me te etera me te tata korekore ki te wai.

- Pumautanga: Ko te 2-Methoxy-4-nitroaniline he ahua pumau i te pāmahana rūma, engari ka pa ki te ra, ki te wera nui ranei, ka pirau ki te whakaputa hau paitini.

 

Whakamahia:

- Pahū: i te aroaro o to ratou roopu nitro, ka taea hoki te whakamahi 2-methoxy-4-nitroaniline i roto i te whakarite o nga pupuhi. Heoi, he tino tairongo me te kino, no reira me tupato te whakahaere.

 

Tikanga:

- Ka taea te whakarite 2-Methoxy-4-nitroaniline ma te nitrification o te para-formaniline. Ka rewa te Formaniline ki roto i te waikawa pungatara mau, katahi ka taapirihia te waikawa nitric kukū ka whakamatao, ka mutu ka wehea te hua.

 

Mōhiohio Haumaru:

- Te paitini: Ko te 2-Methoxy-4-nitroaniline he matū paitini ka puta he tauhohenga paitini mena ka ngongohia, ka uru, ka pa atu ranei ki te kiri.

- Morearea Ahi: 2-Methoxy-4-nitroaniline he nui te morearea pahū, me karohia te pa atu ki te mura, ki te waikura, ki nga rawa muramura ranei.

- Ētahi atu tūpatotanga haumarutanga: I te wa e whakahaere ana i te 2-methoxy-4-nitroaniline, me mau nga taputapu whakamarumaru e tika ana penei i nga karapu, motiiti, me nga kakahu whakamarumaru. Kia tupato i te wa e mahi ana kia kore e puta nga hau paitini me te kore e pa ki nga kanohi, kiri me te manawa. Kia tupato ki te hau i te pāmahana rūma, kia matara atu i te ahi ina whakamahi me te penapena.
