Hoʻolauna

ʻO 2,4-Dichloropyrimidine kahi mea hoʻohui. Eia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 2,4-dichloropyrimidine:

 

ʻAno maikaʻi:

- 2,4-Dichloropyrimidine he aniani kala ʻole me ka ʻala ʻala.

- He haʻahaʻa haʻahaʻa ka solubility i ka wai a ʻoi aku ka nui o ka solubility i nā mea hoʻoheheʻe organik.

 

E hoʻohana:

- ʻO 2,4-Dichloropyrimidine kahi lāʻau pesticide i hoʻohana pinepine ʻia e hoʻopaʻa i ka mauʻu i nā mea kanu.

 

Hanana:

- Hiki ke hoʻomākaukau ʻia ka 2,4-Dichloropyrimidine ma ka hana ʻana i ka pyrimidine me ke kinoea chlorine. E hoʻoheheʻe i nā pyrimidines i loko o ka ferrous chloride a me ka wela i ka mahana kūpono. A laila, lawe ʻia ka hopena chlorination ma ka hoʻokomo ʻana i ke kinoea chlorine i loko o ka ʻōnaehana pane. Loaʻa ka huahana pahuhopu ma o ka crystallization a me ka hoʻomaʻemaʻe ʻana.

 

ʻIke palekana:

- 2,4-Dichloropyrimidine he mea hoʻonāukiuki hiki ke loaʻa ka hopena hoʻonāukiuki i nā maka, kaʻili, a me ka'ōnaehana hanu.

- I ka wā e hoʻohana ai i ka 2,4-dichloropyrimidine, e hoʻokomo i nā mīkina lima pale kūpono, nā aniani, a me nā masks e hōʻoia i ka maikaʻi o ka ea.

- Ma hope koke o ka ʻike ʻana i ka 2,4-dichloropyrimidine, holoi i ka wahi i hoʻopilikia ʻia me ka wai nui a ʻimi koke i ka lāʻau lapaʻau.

- I ka wā o ka mālama ʻana a me ka mālama ʻana, pono e ʻalo ʻia ka hoʻopili ʻana me nā oxidants a me nā ʻakika ikaika e pale aku i nā hopena pōʻino.
