Intshayelelo
I-allyl trifluoroacetate (allyl trifluoroacetate) yi-organic compound kunye ne-chemical formula C5H7F3O2. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:
Indalo:
- allyl trifluoroacetate lulwelo olungenambala kunye nevumba elibuthathaka.
-Indawo yokubilisa malunga ne-68 ° C, kwaye ubuninzi bayo bu malunga ne-1.275 g / mL.
-Inyibilika kwiintlobo ezahlukeneyo ze-solvents eziphilayo, ezifana ne-ethers kunye ne-alcohol.
Sebenzisa:
- allyl trifluoroacetate zisetyenziswa ngokubanzi njenge intermediates zokwenziwa kwi-organic synthesis kwaye ingasetyenziselwa ukudibanisa iintlobo ezahlukeneyo zezinto eziphilayo.
-Ingasetyenziselwa njenge-agent ye-crosslinking ye-polymers kwaye isetyenziselwa ukulungisa izinto ze-polymer, ezifana neengubo kunye neeplastiki.
-Ngenxa yeqondo lokushisa eliphantsi lokutsha, linokusetyenziswa njenge-additive for fuel.
Indlela yokulungiselela:
i-alyl trifluoroacetate inokwenziwa nge-transesterification ye-trifluoroacetic acid kunye ne-alylal alcohol. Iimeko zokusabela zinokufudunyezwa kusetyenziswa i-catalyst efana nesiseko okanye i-acid catalyst.
Ulwazi ngoKhuseleko:
- allyl trifluoroacetate iyacaphukisa kwaye inokubangela umonakalo emehlweni, ulusu kunye nomgudu wokuphefumla.
-Nxiba iiglavu, iiglavu kunye nokukhusela ukuphefumula ngexesha lokusetyenziswa okanye ukusebenza.
-Xa udibana nesikhumba okanye amehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune uncedo lwezonyango.
-Ngexesha lokugcinwa kunye nokusetyenziswa, thintela ukudibanisa ne-oxidants, i-acids kunye ne-alkalis, ngelixa ugcina kude nomlilo kunye neendawo zokushisa eziphezulu.
Nceda uqaphele ukuba i- allyl trifluoroacetate yikhemikhali kwaye kufuneka isetyenziswe ngokuhambelana neenkqubo ezichanekileyo zokhuseleko lwebhubhoratri kwaye igcinwe, iphathwe kwaye ilahlwe ngokuhambelana nemimiselo efanelekileyo.
