Hoʻolauna

ʻO ka Ethyl 2, he mea hoʻohuihui mea ola me ke ʻano kemika C7H5Cl2NO2. He wai waihoʻoluʻu a melemele me ke ʻala ʻala.

 

Hoʻohana pinepine ʻia kēia pūhui ma ke ʻano he mea waena a me ka maka, a he ākea ka nui o nā noi i ka synthesis organik. Hoʻohana pinepine ʻia i ka hoʻomākaukau ʻana i nā pesticides, lāʻau lapaʻau a me nā mea hoʻonaninani a me nā mea ʻē aʻe. Eia kekahi, hiki ke hoʻohana ʻia e aʻo i ka hopena kemika a me nā waiwai o ka ethyl nikotinate.

 

ʻO ke ʻano o ka hoʻomākaukau ʻana i ka ethyl 2 ʻo ia ka hoʻopili ʻana i ka 2,6-dichloropyridine-3-formic acid me ka ethanol, ma lalo o nā kūlana acidic.

 

ethyl 2, aia kekahi pilikia palekana. He lāʻau hoʻonāukiuki ia e hiki ai ke hoʻonāukiuki i ka maka, ka ʻili a me ka ʻōnaehana hanu. I ka lawelawe ʻana, e ʻaʻahu i nā mea pale hanu, nā aniani pale, nā mīkina lima a me nā mea pale wāwae. Eia kekahi, loaʻa iā ia kahi pilikia ahi, pono e kaʻawale mai ke ahi ākea a me ka wela kiʻekiʻe.

 

No nā kumu palekana, i ka wā e hoʻohana ai i ka ethyl 2, e hahai i nā kaʻina hana hoʻokolohua kūpono a e hana i kahi kaiapuni maikaʻi.
