Hoʻolauna
ʻO ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE(ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE) he mea hoʻohuihui. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.
ʻAno:
-Nani: He wai waihoʻoluʻu a i ʻole wai melemele.
-Solubility: Hiki ke hoʻoheheʻe ʻia i nā solvents organik, e like me ka ethanol, ether a me dichloromethane.
-Ka helu hoʻoheheʻe a me ka helu hoʻolapalapa: ʻO kona helu hoʻoheheʻe ma kahi o -8 ° C, a ʻo kona helu hoʻolapalapa ma kahi o 108-110 ° C.
E hoʻohana:
-regent in Advanced Organic Synthesis: ETHYL 4,4, 4-trifluororo-2-butynoate hiki ke hoʻohana ʻia ma ke ʻano he reagent koʻikoʻi i ka synthesis organik. Hiki iā ia ke komo i loko o nā ʻano hopena kūlohelohe, e like me ka acylation, condensation a me cyclization reactions, hoʻohana ʻia e synthesize i nā ʻano mea like ʻole.
-Material chemistry: Hiki ke hoʻohana ʻia no kekahi mau hopena i ka kemika polymer, e like me nā mea hoʻohui crosslinking no nā polymers synthetic.
Hanana:
Hiki ke hoʻomākaukau ʻia ʻo ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE e nā pae aʻe:
1. ʻO ka mua, ua hoʻopili ʻia ka butynol (2-butynol) me ka hydrogen fluoride anhydrous e hana ai i ka butynyl fluoride.
2. A laila, hoʻopili ʻia ka butynyl fluoride me ka ETHYL chloroacetate e hana ai i ka ETHYL 4,4, 4-trifluororo-2-butynoate.
ʻIke palekana:
- Pono ka ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE e hōʻalo i ka hoʻokuʻu lōʻihi ʻana i ka ea no ka mea paʻakikī ia i ka wai a me ka wai.
-Pono ia e pale aku i nā lapalapa ahi a me nā wela kiʻekiʻe i ka wā o ka hana a me ka mālama ʻana, no ka mea hiki ke wela.
- Pono e mālama ʻia nā hana pale kūpono i ka wā e hoʻohana ai a mālama ʻia, me ke komo ʻana i nā mīkina lima, nā maka a me nā aniani pale.
- Pono e mālama ʻia ma kahi ʻoluʻolu, maloʻo a me ka makani maikaʻi.
