Intshayelelo

Ethyl allylenate. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-ethyl allylate:

 

Umgangatho:

I-Ethyl allyl proponate lulwelo olunevumba elibi, lunyibilika kwiintlobo ngeentlobo zezinyibilikisi eziphilayo ezifana ne-alcohol, ii-ethers, njl., kodwa ezinganyibilikiyo emanzini.

- I-Ethyl allyl proponate inozinzo oluhle, kodwa i-polymerization yenzeka ekukhanyeni kwelanga.

 

Sebenzisa:

- I-Ethyl allyl propionate yinto ebalulekileyo ephakathi kwi-organic synthesis, enokusetyenziswa kwimveliso yeekhemikhali ezifana neziqholo, iiplastiki kunye nedayi.

- Inokusetyenziswa njenge-solvent kwiindawo zoshishino ezifana neengubo, ii-inki, iiglues, njl.

- I-Ethyl allyl ingasetyenziselwa ukulungiswa kwee-resin, i-lubricant kunye ne-plasticizers.

 

Indlela:

- I-Ethyl allyl idla ngokubunjwa ngokusabela kwe-ethylene kunye ne-acrylic acid, ethi emva koko ifakwe kwi-ethyl allylate.

- Kwishishini, ii-catalysts ezifana ne-sulfuric acid zihlala zisetyenziselwa ukuququzelela ukusabela.

 

Ulwazi ngoKhuseleko:

- I-Ethyl allyl lulwelo olunokutsha kwaye kufuneka luthintelwe ekudibaneni namadangatye avulekileyo, amaqondo obushushu aphezulu, kunye ne-oxidizing agents.

- Nxiba izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu, iiglasi, kunye nempahla yokuzikhusela xa usetyenziswa.

- Gwema ukudibanisa nolusu, amehlo kunye nokuphefumula kwe-ethyl allylenate, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune unyango ukuba uyakwenza.

- Iimeko ezifanelekileyo zokungenisa umoya kufuneka zithathwe xa ugcina kwaye usebenzisa i-ethyl allylenate.

- Xa ulahla inkunkuma, landela imimiselo yokusingqongileyo yendawo.

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
