Nhanganyaya
4,4′-(2,2,2-trifluoro-1-trifluoromethyl)ethylenebis(1,2-benzenedicarboxylic acid) is an organic compound. Ichena crystalline powder ine high thermal kugadzikana uye kusagadzikana kwemamiriro ekunze.
Mushonga wacho unogona kushandiswa kugadzira zvinhu zvepolyester yepamusoro-soro nepamusoro-oxidation resistance uye kupisa kupisa, uye ine zvakasiyana-siyana zvekushandisa. Inogona kushandiswa sechigadziriso kuvandudza zvimiro zvepolyester zvinhu, senge ductility, simba, uye kuramba mamiriro ekunze. Inogona zvakare kushandiswa sephotosensitizer uye yekuwedzera kune polymerization catalysts.
Nzira yekugadzirira ye4,4′-(2,2,2-trifluoro-1-trifluoromethyl)ethylenebis(1,2-benzenedicarboxylic acid) yakaoma uye inoda kuwanikwa kuburikidza ne-multi-step reaction. Nzira inowanzoshandiswa ndeyekuita phthalic acid nemethylene trifluoride pasi pemamiriro ealkaline kupa 4,4′-(2,2,2-trifluoro-1-trifluoromethyl)ethylenebis(1,2-benzenedicarboxylic acid).
Ruzivo rwekuchengetedza: Nzira dzakakodzera dzekubata uye dziviriro dzinofanirwa kutorwa panguva yekugadzirira uye kushandiswa kwekomboni iyi. Iine humwe muchetura uye kushatirwa, uye inofanira kudzivirirwa kubva mukufemesa huruva uye kusangana neganda, maziso, nezvimwewo. Pfekai magirovhosi ekudzivirira, masiki, uye magirazi kuti muve nechokwadi chekufefetera kwakanaka panguva yekushanda.
