Txoj kev:
ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE tuaj yeem npaj tau los ntawm cov kauj ruam hauv qab no:
1. Ua ntej, butynol (2-butynol) yog reacted nrog anhydrous hydrogen fluoride los tsim butynyl fluoride.
2. Tom qab ntawd, butynyl fluoride reacted nrog ETHYL chloroacetate los tsim ETHYL 4,4, 4-trifluororo-2-butynoate.
Cov ntaub ntawv kev nyab xeeb:
- ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE yuav tsum zam kom tsis txhob raug huab cua ntev vim tias nws nkag siab rau cov dej noo thiab dej.
-Nws yuav tsum tsis txhob qhib nplaim taws thiab kub siab thaum lub sijhawm ua haujlwm thiab khaws cia, vim nws yog nplaim taws.
-Kev tiv thaiv tsim nyog yuav tsum tau ua thaum siv thiab tuav nws, suav nrog cov hnab looj tes, qhov ncauj qhov ntswg thiab tsom iav tiv thaiv.
-Nws yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav thiab zoo-ventilated.
