Isingeniso
I-ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE(ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE) iyinhlanganisela yezinto eziphilayo. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: Ngokuvamile uketshezi olungenambala noma uketshezi oluphuzi.
-I-Solubility: Ingancibilika kuma-organic solvents, njenge-ethanol, i-ether ne-dichloromethane.
-Iphuzu lokuncibilika nendawo yokubilisa: Indawo yayo yokuncibilika icishe ibe -8°C, futhi indawo yayo yokubila icishe ibe ngu-108-110°C.
Sebenzisa:
-i-reagent ku-Advanced Organic Synthesis: I-ETHYL 4,4, 4-trifluororo-2-butynoate ingasetshenziswa njenge-reagent ebalulekile ku-organic synthesis. Ingabamba iqhaza ekuphenduleni okuhlukahlukene kwemvelo, okufana ne-acylation, ukufingqa kanye nokusabela kwe-cyclization, okusetshenziselwa ukuhlanganisa inhlanganisela yezinto eziphilayo.
-I-Material chemistry: Ingasetshenziswa futhi ekuphenduleni okuthile kumakhemikhali e-polymer, njengama-crosslinking agents kuma-polymers okwenziwa.
Indlela:
I-ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE ingalungiswa ngezinyathelo ezilandelayo:
1. Okokuqala, i-butynol (2-butynol) iphendulwa nge-anhydrous hydrogen fluoride ukuze ikhiqize i-butynyl fluoride.
2. Bese, i-butynyl fluoride isabela nge-ETHYL chloroacetate ukukhiqiza i-ETHYL 4,4, 4-trifluororo-2-butynoate.
Ulwazi Lokuphepha:
- I-ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE kufanele igweme ukuchayeka isikhathi eside emoyeni ngoba izwela umswakama kanye namanzi.
-Kufanele kugweme amalangabi avulekile namazinga okushisa aphezulu ngesikhathi sokusebenza nokugcinwa, ngoba kuyavutha.
-Izinyathelo ezifanele zokuzivikela kufanele zithathwe uma uyisebenzisa futhi uyiphatha, kuhlanganise nokugqoka amagilavu, izifihla-buso nezibuko zokuzivikela.
-Kufanele igcinwe endaweni epholile, eyomile futhi engenawo umoya.
