4 6-Dichloro-2-methylpyrimidine（CAS# 1780-26-3) hoʻolauna
ʻO 2-Methyl-4,6-dichloropyrimidine, i ʻike ʻia ʻo 2,4,6-trichloropyrimidine a i ʻole DCM, he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka pūhui:
ʻAno maikaʻi:
- Ke ʻano: 2-methyl-4,6-dichloropyrimidine he aniani keʻokeʻo a i ʻole ka pauka crystalline kala ʻole.
- Solubility: He haʻahaʻa ka solubility i ka wai akā ʻoi aku ka maikaʻi o ka solubility i nā mea hoʻoheheʻe organik.
- Nā waiwai kemika: He pūhui paʻa loa ʻaʻole hiki ke hoʻoheheʻe ʻia a i ʻole ka hopena ma lalo o nā kūlana hoʻololi kemika maʻamau.
E hoʻohana:
- Solvent: 2-Methyl-4,6-dichloropyrimidine he mea hoʻohana maʻamau i hoʻohana ʻia i loko o nā hale hana kemika e hoʻopau i nā mea hoʻohuihui, ʻoi aku ka mea hiki ʻole ke hoʻoheheʻe ʻia i ka wai.
Hanana:
- Hiki ke loaʻa ka 2-Methyl-4,6-dichloropyrimidine ma ka hopena o 2-methylpyrimidine me ke kinoea chlorine. Pono e hoʻokō ʻia kēia hopena ma lalo o nā kūlana ventilation kūpono.
ʻIke palekana:
- ʻO 2-Methyl-4,6-dichloropyrimidine he mea hoʻohuihui me kekahi mea ʻona. He mea hoʻonāukiuki a ʻino i ka maka, ka ʻili, a me ka ʻōpū hanu. Pono e hoʻohana ʻia nā mīkina lima, nā maka aniani, a me nā mea pale hanu i ka wā e hoʻohana ai e hōʻoia i ka pono o ka ea. I ka hihia o ka ingestion a i ʻole inhalation, e ʻimi koke i ka lāʻau lapaʻau.
- ʻO 2-Methyl-4,6-dichloropyrimidine ka mea e hoʻopilikia ai i ke kaiapuni a he mea ʻawaʻawa ia i nā meaola wai a me ka lepo. I ka hoʻohana ʻana a me ka hoʻolei ʻana i ka ʻōpala, pono e hahai i ke kumu o ka mālama ʻana i ke kaiapuni, a pono e hoʻolei pololei ʻia ka ʻōpala.
