Intshayelelo

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

 

Umgangatho:

- Imbonakalo: Ulwelo olungenambala

- Ivumba: iChampagne kunye namanqaku aneziqhamo

- Ukunyibilika: Inyibilika kwizinyibilikisi eziphilayo, ezinganyibilikiyo emanzini

 

Sebenzisa:

- Izinyibilikisi: Zisetyenziswa kakhulu njengezinyibilikisi zendalo kwimizi-mveliso efana neengubo, ivanishi, ii-inki kunye nezinto ezincamathelayo.

 

Indlela:

Ukulungiswa kwe-ethyl butyrate ngokuqhelekileyo kuqhutyelwa yi-esterification. I-asidi ye-Acidic kunye ne-butanol ziphendulwa phambi kwee-catalysts ze-asidi ezifana ne-asidi ye-sulfuric ukuvelisa i-ethyl butyrate kunye namanzi.

 

Ulwazi ngoKhuseleko:

I-Ethyl butyrate ngokuqhelekileyo ithathwa njengekhemikhali ekhuselekileyo, kodwa kufuneka kuqatshelwe la manyathelo okhuseleko alandelayo:

- Kuphephe ukuphefumla umphunga okanye iigesi kwaye uqinisekise indawo yokusebenza enomoya kakuhle.

- Kulumkele ukudityaniswa kwesikhumba kwaye uhlambulule kwangoko ngamanzi ukuba ichukumisa ulusu.

- Kuphephe ukusela ngengozi, kwaye ufune unyango ngokukhawuleza ukuba uthe waginya ngempazamo.

-Zigcine kude nomlilo kunye namaqondo obushushu aphezulu, gcina utywiniwe, kwaye uphephe ukunxibelelana nee-oxidants.

 

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