Hoʻolauna

ʻO ka Ethyl, ʻo C9H9NO4. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.

 

ʻAno:

ʻO ka Ethyl kahi aniani melemele a i ʻole ka pauka me kahi hiʻohiʻona momona a me kahi ʻala kūikawā. Hiki ke hoʻoheheʻe ʻia i loko o ka hapa nui o nā mea hoʻoheheʻe organik a emi ʻole i ka wai.

 

E hoʻohana:

ʻO ka Ethyl kahi hui waena synthesis organik, i hoʻohana nui ʻia i ka ʻoihana pesticide a me ka hana lāʻau lapaʻau. Hiki ke hoʻohana ʻia e synthesize i nā ʻano kemika biologically active, e like me nā pesticides, fungicides, anti-tumor drugs, etc.

 

Kaʻina hoʻomākaukau:

Hoʻomākaukau ʻia ʻo Ethyl e ka synthesis kemika. ʻO kahi ala maʻamau ma ka esterification o ka 2-methyl-5-nitronicotinic acid. Ma ka hana kiko'ī, hoʻopili ʻia ka 2-methyl-5-nitronicotinic acid me ka anhydride a me ka alkaline catalyst e hana ai i ka Ethyl.

 

ʻIke palekana:

Hiki i ka Ethyl ke hoʻonāukiuki i ka ʻili a me ka pōʻino i ka maka, ka ʻōpū hanu a me ka ʻōpū hanu. No laila, pono e lawe ʻia nā ʻano pale kūpono i ka wā e mālama ai i ka mea, e like me ke komo ʻana i nā mīkina lima a me nā aniani pale, e hōʻoia i ka hana ʻana ma lalo o nā kūlana ventilated maikaʻi. Eia kekahi, pono e mālama ʻia ma kahi maloʻo, ʻoluʻolu, maikaʻi-ventilated, kahi mamao mai nā mea puhi a me nā mea ʻona. E ʻoluʻolu e nānā i ka ʻikepili palekana kūpono a me nā ʻōlelo aʻoaʻo no nā hana palekana e pili ana i kēia mea.
