Intshayelelo
I-Fluoropropionone (ekwaziwa njenge-benzene 1-fluoroacetone) yikhompawundi ephilayo. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-fluoropropionone:
Umgangatho:
Imbonakalo: I-Fluoropropion lulwelo olungenambala kunye nevumba elibukhali elibukhali.
Uxinaniso: Ubuninzi be-fluoropropion bumalunga ne-1.09 g/cm³.
Ukunyibilika: Inyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol, i-ether kunye ne-acetone, kodwa ayinyibiliki emanzini.
Ukusebenza kwakhona: Inokusabela nge-arhente yokunciphisa ukuvelisa iikhompawundi zotywala ezihambelanayo. I-Fluoropropiophenone inokuthi ifumane iimpendulo eziqhumayo phantsi kwesenzo se-oxidizing agents.
Sebenzisa:
I-Fluoropropiophenone inosetyenziso oluthile, ingakumbi kubandakanywa:
Njenge-organic synthesis reagent: I-Fluoropropion ingasetyenziswa njenge-ligand okanye ithathe inxaxheba kwiimpendulo ze-organic complex, ezifana ne-fluorination kunye ne-acylation.
Njenge-surfactant: ngenxa yesakhiwo sayo esikhethekileyo kunye neempawu, inamandla okusebenza kwi-wetting, decontamination and emulsification.
Indlela:
I-Fluoropylacetone inokulungiswa ngokusabela kwe-acetone ene-fluorinated ne-benzene, ngokubanzi phantsi kwemeko yokongeza i-agent agent catalyst efana ne-boron trifluoride (BF3) okanye i-aluminium fluoride (AlF3) kwi-atmosphere engasebenzi.
Ulwazi ngoKhuseleko:
I-Fluoropropion iyacaphukisa kwaye inokubangela ukucaphuka kunye nokutshisa xa udibana nolusu kunye namehlo. Izilumkiso ezifanelekileyo, ezinjengeeglavu, iiglasi, kunye nempahla ekhuselayo, kufuneka zithathwe ngexesha lokudibana.
Iyatsha kwaye kufuneka igcinwe kude namadangatye avulekileyo kunye nemithombo yobushushu obuphezulu. Xa uphatha kwaye ugcina, amanyathelo okuthintela umlilo kufuneka athathwe.
Xa isetyenziswa kwiilabhoratri kunye namashishini, iinkqubo ezifanelekileyo zokusebenza kufuneka zilandelwe ukuphepha ukuphendula okungakhuselekanga kunye nezinye izinto ezinobungozi.
I-Fluoropionone kufuneka igcinwe kwindawo epholileyo, eyomileyo kwaye engenamoya, kude nomlilo kunye ne-oxidants.
