Tikanga Whakaritenga me te Tukatuka Whakaputa

Ko te waikawa Trifluoroacetic he reagent waihanga pararopi nui, mai i reira ka taea te whakahiato i nga momo puhui fluorine, pesticides me nga waikano.Ko te waikawa Trifluoroacetic ano he whakakorikori mo te esterification me te condensation.Ka taea hoki te whakamahi hei kaihoko tiaki mo nga roopu hydroxyl me te amino, ka taea te whakamahi mo te whakahiato o te huka me te polypeptide.
Ko te waikawa Trifluoroacetic he maha nga huarahi whakarite:
1.Ka whiwhihia e te oxidation o te 3,3,3- trifluoropropene me te pāhare pāporo.
2.Ka whiwhihia e te fluorination electrochemical o te waikawa acetic (acetyl chloride me te acetic anhydride) me te waikawa hydrofluoric me te konutai fluoride, a ka hydrolysis.
3.Ka whiwhihia e te oxidation o te 1,1,1- trifluoro -2,3,3- trichloropropene e te pāhare pāporo.Ka taea e te Swarts fluorination te hexachloropropene te hanga i tenei rauemi mata.
4. Ka whakaritea e te oxidation o te 2,3- dichlorohexafluoro -2- butene.
5.Ka hangaia te Trifluoroacetonitrile e te tauhohenga i waenga i te trichloroacetonitrile me te hauwai fluoride, katahi ka hauwai.
6.Ka whiwhihia e te oxidation o trifluorotoluene.

Whakamahinga

Ko te waikawa Trifluoroacetic te nuinga e whakamahia ana i roto i te hanga pesticides hou, rongoa me nga waikano, a he nui ano te tono me te whanaketanga o nga rauemi, whakarewa me etahi atu mara.
