Intshayelelo
1,1,1-Trifluoroacetone. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Umgangatho:
I-1,1,1-trifluoroacetone lulwelo olunokutsha kunye nencasa eqholiweyo neswiti. Izinzile kakhulu kwiikhemikhali, ayiboli lula ngeeasidi, ialkali okanye i-oxidants, kwaye ayigalelwa lula yihydrolyzed. Inonyibiliko olulungileyo kwaye iyanyibilika kwiintlobo ngeentlobo zezinyibilikisi eziphilayo ezifana ne-alcohol, ii-ethers, kunye nee-ketones.
Sebenzisa:
I-1,1,1-Trifluoroacetone inoluhlu olubanzi lokusetyenziswa kwishishini. Sisinyibilikisi esibalulekileyo esinokusetyenziswa kwiindawo ezifana nezaleko, izicoci, iidegreaser, kunye nezitywini zegesi. Isenokusetyenziswa njenge-arhente yokudumba ye-polyurethane, i-polyester kunye ne-PTFE, kunye ne-plasticizer kunye ne-flame retardant ye-coatings.
Indlela:
Ukulungiswa kwe-1,1,1-trifluoroacetone ngokukodwa kwenziwa ngokusabela kwe-reagent fluorinated nge-acetone. Indlela eqhelekileyo kukusebenzisa i-ammonium bifluoride (NH4HF2) okanye i-hydrogen fluoride (HF) ukusabela nge-acetone phambi kwe-catalyst ukuvelisa i-1,1,1-trifluoroacetone. Le nkqubo yokusabela kufuneka iqhutywe phantsi kolawulo olungqongqo kuba i-hydrogen fluoride yigesi eyityhefu.
Ulwazi ngoKhuseleko:
I-1,1,1-Trifluoroacetone lulwelo olunokutsha olunokuthi luqhume xa luvezwe kwidangatye elivulekileyo okanye ubushushu obuphezulu. Inokukhanya okuphantsi kwe-flash point kunye nobushushu bokuziqhelanisa, kwaye kufuneka iphathwe kwaye igcinwe ngokufanelekileyo, kude nezinto ezivuthayo kunye nezinto ezishushu. Izixhobo ezifanelekileyo zokukhusela ezifana nempahla yamehlo ekhuselayo, iiglavu kunye nempahla yokukhusela kufuneka zinxitywe xa zisetyenziswa. Kufuneka kuqinisekiswe ukuba isebenza kwindawo enomoya kwaye ugweme ukuphefumla umphunga wayo njengoko unokubangela umonakalo kumzimba womntu. Xa udibana nesikhumba okanye amehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune uncedo lwezonyango.
