Mawu Oyamba
ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE(ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE) ndi organic compound. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
-Maonekedwe: Nthawi zambiri ndi madzi opanda mtundu kapena achikasu.
-Kusungunuka: Kutha kusungunuka mu zosungunulira za organic, monga ethanol, etha ndi dichloromethane.
-Posungunuka ndi kuwira: Malo ake osungunuka ndi pafupifupi -8 ° C, ndipo kuwira kwake ndi pafupifupi 108-110 ° C.
Gwiritsani ntchito:
-reagent mu Advanced Organic Synthesis: ETHYL 4,4, 4-trifluororo-2-butynoate ingagwiritsidwe ntchito ngati reagent yofunikira mu organic synthesis. Itha kutenga nawo mbali pamachitidwe osiyanasiyana achilengedwe, monga ma acylation, condensation ndi ma cyclization, omwe amagwiritsidwa ntchito popanga mitundu yosiyanasiyana yamagulu.
-Material chemistry: Itha kugwiritsidwanso ntchito pazinthu zina zama polymer chemistry, monga crosslinking agents for synthetic polima.
Njira:
ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE ikhoza kukonzedwa ndi njira zotsatirazi:
1. Choyamba, butynol (2-butynol) imayendetsedwa ndi anhydrous hydrogen fluoride kupanga butynyl fluoride.
2. Kenako, butynyl fluoride imayendetsedwa ndi ETHYL chloroacetate kupanga ETHYL 4,4, 4-trifluororo-2-butynoate.
Zambiri Zachitetezo:
- ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE iyenera kupewa kutengera mpweya kwa nthawi yayitali chifukwa imakhudzidwa ndi chinyezi ndi madzi.
-Iyenera kupewa moto wotseguka komanso kutentha kwambiri pakugwira ntchito ndi kusungirako, chifukwa imatha kuyaka.
- Njira zodzitetezera ziyenera kuchitidwa mukamagwiritsa ntchito ndikuzigwira, kuphatikiza kuvala magolovesi, masks ndi magalasi oteteza.
-Zizisungidwa pamalo ozizira, owuma komanso mpweya wabwino.
