Imikhiqizo

I-Trifluoroacetamide, enefomula yamakhemikhali i-CF3CONH2, iyinhlanganisela ethola ukusetshenziswa okuhlukahlukene emikhakheni ehlukene, okuhlanganisa imikhakha yezemithi, ye-agrochemical, kanye nezimboni.Embonini yezemithi, i-trifluoroacetamide idlala indima ebalulekile njengeqembu elivikelayo ekuhlanganiseni kwezinto eziphilayo.Amaqembu okuvikela angamaqembu asebenzayo axhunywe okwesikhashana kuma-athomu athile ku-molecule ukuvimbela ukusabela okungafuneki phakathi nokuguqulwa kwamakhemikhali.I-Trifluoroacetamide isebenza njengeqembu elivikela ama-amine, ikakhulukazi ama-amine ayinhloko.Ngokukhipha i-amine eyinhloko nge-trifluoroacetamide, ivimbela ngokuphumelelayo ukusabela okungafuneki ohlangothini, okuvumela ukuguqulwa okukhethiwe kwamanye amaqembu asebenzayo akhona ku-molecule.Lelisu lokuvikela-lokuvikela lisetshenziswa kakhulu ekuhlanganisweni kwezinhlanganisela zemithi eziyinkimbinkimbi, ukuqinisekisa ukuthi ukusabela kwamakhemikhali okuthile kwenzeka kuphela kumasayithi anqunywe kusengaphambili.Ngaphezu kwalokho, i-trifluoroacetamide isetshenziswa ekukhiqizeni ama-reagents e-Vilsmeier-Haack.Ukusabela kwe-Vilsmeier-Haack ukusabela kwamakhemikhali okusetshenziselwa ukuhlanganiswa kwezinto eziphilayo ezihlukahlukene, kuhlanganise nama-aldehyde anuka kamnandi nama-ketone.I-Trifluoroacetamide, ihlanganiswe ne-acid chloride kanye ne-Lewis acid catalyst, yakha i-reagent ye-Vilsmeier-Haack, esebenza njengethuluzi eliguquguqukayo lokusebenzisa izinhlanganisela ezinuka kamnandi.Lokhu kusabela kusetshenziswa kakhulu embonini yezemithi ukuze kuhlanganiswe izithako zemithi ezimaphakathi nezisebenzayo (ama-API). Emkhakheni we-agrochemical, i-trifluoroacetamide isetshenziswa njengesimaphakathi ekuhlanganiseni ama-herbicides nezibulala-zinambuzane.Imvelo esebenzayo yenhlanganisela ivumela ukwethulwa kwamaqembu athile asebenzayo adingekayo ekusebenzeni kwe-agrochemical.Ama-molecule asekelwe ku-Trifluoroacetamide angabonisa izakhiwo ezithuthukisiwe zokubulala ukhula noma izibulala-zinambuzane uma ziqhathaniswa nama-analogue awo, athuthukise ukusebenza kahle kwawo ekuvikeleni izitshalo okhula, izinambuzane, nezifo.Okuphuma kokuphuma kwe-Trifluoroacetamide kubonise umsebenzi onamandla ngokumelene nenani elibanzi lezinto eziphilayo eziqondiwe kuyilapho kunciphisa umthelela wazo omubi endaweni ezungezile.Ngaphezu kwalokho, i-trifluoroacetamide iyasebenza emkhakheni wezimboni.Ihilelekile ekukhiqizeni izincibilikisi, njenge-N-methyl-N-(trifluoroacetyl)acetamide (MTAA), esetshenziswa ezinqubweni ezihlukahlukene zezimboni.Izinyibilikisi eziqukethe i-Trifluoroacetamide zinezinto ezifiselekayo, okuhlanganisa amaphuzu aphezulu abilayo, ukucindezela komhwamuko ophansi, nokuzinza kwamakhemikhali, okuwenza afanelekele izinhlelo zokusebenza ezifana nokukhipha, ukuhlukaniswa, nokuhlanzwa kwezinhlanganisela eziphilayo. ikakhulukazi ekusetshenzisweni kwemithi kanye ne-agrochemical.Isebenza njengeqembu elivikelayo lama-amine, okuvumela ukuguqulwa okukhethiwe ngesikhathi sokuhlanganiswa kwezinto eziphilayo eziyinkimbinkimbi.Amakhompiyutha asuselwa ku-Trifluoroacetamide athola ukusetshenziswa njengemaphakathi ekukhiqizweni kwemithi, ama-herbicides, nezibulala-zinambuzane, okuhlinzeka ngokusebenza okuthuthukisiwe nokusimama kwemvelo.Ukwengeza, i-trifluoroacetamide ibandakanyeka ekukhiqizeni izincibilikisi ezikhethekile ezisetshenziswa ezinqubweni ezihlukahlukene zezimboni.Ukuguquguquka nokusebenza kabusha kwe-trifluoroacetamide kuyenza ibe inhlanganisela ebalulekile ezimbonini eziningi.
