Hoʻolauna
ʻO ka Ethyl 2-choro-3-keto-4, 4,4-trifluorobutyrate he mea hoʻohuihui me ke ʻano kemika C6H7ClF3O3. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana:
ʻAno:
-Nani: ʻAʻole kala a i ʻole ka wai melemele māmā
-Ka helu hehee:-60°C
-Ka Lae paila: 118-120°C
-Ka mānoanoa: 1.432 g/mL
-Solubility: Hiki ke hoʻoheheʻe ʻia i ka wai a me ka hapa nui o nā mea hoʻoheheʻe organik
E hoʻohana:
- Hoʻohana pinepine ʻia ka ethyl 2-chroo-3-keto-4, 4,4-trifluorobutyrate ma ke ʻano he reagent koʻikoʻi i ka synthesis organik. Hiki ke hoʻohana ʻia e synthesize i nā pūhui ʻē aʻe, e like me nā lāʻau lapaʻau, pesticides, dyes, etc.
-Hiki ke hoʻohana ʻia i mea hoʻohui no nā huahana mahiʻai antifouling agent, pena a me ke kāpili.
Kaʻina hoʻomākaukau:
ʻO ka synthesis o ka ethyl 2-chloro-3-keto-4,4,4-trifluorobutyrate ka mea maʻamau e hana ʻia e nā pae aʻe:
Hoʻopili ka 1.2-chloro-4, 4,4-trifluoroacetic acid me ka chloroacetic anhydride e hana i ka 2-chloro-4, 4,4-trifluoroacetyl chloride.
Hoʻopili ʻia ka 2.2-chloro-4, 4,4-trifluoroacetyl chloride me ka ethyl acetate e hana i ka huahana hope ethyl 2-chloro-3-keto-4, 4,4-trifluobutyrate.
ʻIke palekana:
-ʻO ka Ethyl 2-chloro-3-keto-4,4,4-trifluorobutyrate he mea hoʻoheheʻe ʻia e hiki ke hoʻopilikia i ke olakino.
-I ka wā e hoʻohana ai, pono e mālama i nā kaʻina hana palekana, e like me ke komo ʻana i nā aniani pale a me nā mīkina lima.
-E hōʻalo i ka pili ʻana me ka ʻili a me nā maka, pale i ka hoʻohu ʻana i kona mahu, a mālama i ka ea maikaʻi.
-I ka mālama ʻana, e hoʻolohe i ka pale ʻana i ke ahi a me ke kiʻekiʻe o ka wela, a pale i ke ahi a me nā mea hiki ke ahi.
E ʻoluʻolu e hoʻomaopopo no ka hoʻohana ʻana a me ka lawelawe ʻana i nā kemika, pono e hahai ʻia nā kaʻina hana palekana, a pono e heluhelu pono a hahai ʻia ka Pepa ʻIkepili Palekana Material (MSDS) pili.
