Kupu Whakataki
Ko te ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE(ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE) he pūhui waro. Ko nga korero e whai ake nei mo tona ahuatanga, te whakamahinga, te whakarite me nga korero haumaru:
Taiao:
-Te ahua: Ko te tikanga he wai kore tae, he wai kowhai ranei.
-Solubility: Ka taea te rewa i roto i nga whakarewa pararopi, penei i te ethanol, ether me te dichloromethane.
-Ira whakarewa me te ira koropuke: Ko tona ira whakarewa he tata ki te -8°C, a, ko te 108-110°C tona ira whakarewa.
Whakamahia:
-reagent in Advanced Organic Synthesis: ETHYL 4,4, 4-trifluororo-2-butynoate ka taea te whakamahi hei reagent nui i roto i te whakahiato waro. Ka taea e ia te uru atu ki nga momo tauhohenga waro, penei i te acylation, te condensation me te cyclization tauhohenga, e whakamahia ana ki te whakahiato i nga momo puhui waro.
-Material matū: Ka taea hoki te whakamahi mo etahi tauhohenga i roto i te matū polymer, penei i nga kaihoko honohono mo nga polymers waihanga.
Tikanga:
ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE ka taea te whakarite ma nga waahanga e whai ake nei:
1. Tuatahi, ka tauhohehia te butynol (2-butynol) ki te hauwai fluoride anhydrous ki te whakaputa butynyl fluoride.
2. Na, ka tauhohe te butynyl fluoride ki te ETHYL chloroacetate hei whakaputa i te ETHYL 4,4, 4-trifluororo-2-butynoate.
Mōhiohio Haumaru:
- Ko te ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE me karo i te wa roa ki te hau na te mea he ngawari ki te makuku me te wai.
-Me karo i nga mura tuwhera me nga wera nui i te wa e mahi ana me te rokiroki, na te mea he mura.
-Me mahi nga tikanga whakamarumaru i te wa e whakamahi ana me te whakahaere, tae atu ki te mau karapu, kanohi kanohi me nga karaehe whakamarumaru.
-Me penapena ki tetahi waahi makariri, maroke me te hau pai.
