Intshayelelo
I-Ethyl pentafluoropropionate (ekwaziwa njenge-methyl pentafluoropropionate okanye i-ethyl pentafluoropropionate) lulwelo olungenambala nevumba elinamandla. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Umgangatho:
- Ukunyibilika: Inyibilika ngezinyibilikisi ezininzi zendalo, kodwa phantse azinyibiliki emanzini
- Ukutsha: igesi enokutsha, eyityhefu yefluoride inokuveliswa xa ibekwe emlilweni okanye kumaqondo obushushu aphezulu
Sebenzisa:
-I-Ethyl pentafluoropropionate isetyenziswa ngokubanzi kwi-organic synthesis njenge-solvent kunye ne-catalyst ye-organic synthesis reactions.
-Inokuthi isetyenziswe njengento ekrwada yokugquma umphezulu ukunyusa ukuxhathisa kwe-corrosion kunye nokumelana nokufuma kwemathiriyeli.
- Kunyango lomphezulu kunye nokucocwa kwezinto kushishino lombane
Indlela:
- Ukulungiswa kwe-ethyl pentafluoropropionate ngokuqhelekileyo kuthatha i-fluoride reaction enzima, esebenzisa i-pentafluoropropionic acid ukusabela nge-methanol okanye i-ethanol ukuvelisa i-ethyl pentafluoropropionate. Iimeko zokusabela zifuna ubushushu obulawulwayo kunye nexesha lokusabela ukuqinisekisa isivuno kunye nomgangatho wemveliso.
Ulwazi ngoKhuseleko:
- I-Ethyl pentafluoropropionate iyacaphukisa kwaye kufuneka igwenywe ekudibaneni nolusu kunye namehlo. Iiglavu ezikhuselayo, iiglasi kunye nempahla ekhuselayo kufuneka zinxitywe xa kusenziwa utyando.
- I-Ethyl pentafluoropropionate lulwelo olunokutsha kwaye kufuneka lugcinwe kude nomlilo kunye namaqondo obushushu aphezulu. Kulumkele ukudibana nee-oxidizing agents ezinamandla ukunqanda umlilo okanye ugqabhuko-dubulo.
- Sebenza kwindawo engena umoya kwaye uphephe ukuphefumla imiphunga yayo ngexesha lokusebenza.
- Kwimeko yokudibanisa ngengozi okanye ukuphefumla, hamba ngokukhawuleza emoyeni omtsha kwaye ufune iingcebiso zonyango ukuba kuyimfuneko.
