Hanyar Shirye-shiryen da Tsarin Samfura

Trifluoroacetic acid shine muhimmin reagent na kwayoyin halitta, wanda za'a iya haɗa nau'ikan abubuwan da suka ƙunshi furotin, magungunan kashe qwari da rini.Trifluoroacetic acid kuma shine mai haɓakawa don haɓakawa da haɓakawa.Hakanan za'a iya amfani dashi azaman wakili na kariya ga ƙungiyoyin hydroxyl da amino, kuma ana iya amfani dashi don haɗin sukari da polypeptide.
Trifluoroacetic acid yana da hanyoyi masu yawa na shirye-shirye:
1.An samu ta hanyar hadawan abu da iskar shaka na 3,3,3- trifluoropropene tare da potassium permanganate.
2.An samu ta hanyar electrochemical fluorination na acetic acid (ko acetyl chloride da acetic anhydride) tare da hydrofluoric acid da sodium fluoride, sa'an nan kuma hydrolysis.
3.An samu ta hanyar hadawan abu da iskar shaka na 1,1,1- trifluoro -2,3,3- trichloropropene ta potassium permanganate.Ana iya shirya wannan ɗanyen abu ta hanyar Swarts fluorination na hexachloropropene.
4.An shirya shi ta hanyar oxidation na 2,3- dichlorohexafluoro -2- butene.
5.Trifluoroacetonitrile yana haifar da amsawa tsakanin trichloroacetonitrile da hydrogen fluoride, sa'an nan kuma hydrolyzed.
6.An samu ta hanyar hadawan abu da iskar shaka na trifluorotoluene.

Amfani

Trifluoroacetic acid ana amfani dashi galibi a cikin samar da sabbin magungunan kashe qwari, magunguna da rini, kuma yana da babban aikace-aikace da yuwuwar haɓakawa a cikin kayan, kaushi da sauran fannoni.
