Intshayelelo

Ethyl benzoate) yikhompawundi ephilayo elulwelo olungenambala kubushushu begumbi. Olu lulandelayo lulwazi kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nokhuseleko lwe-ethyl benzoate:

 

Umgangatho:

Inevumba elimnandi kwaye iyaguquguquka.

Inyibilika kwizinyibilikisi zendalo ezifana ne-ethanol, i-ether, njl., ezinganyibilikiyo emanzini.

 

Sebenzisa:

I-Ethyl benzoate isetyenziswa ikakhulu njengesinyibilikisi kwizicelo zemizi-mveliso ezifana nepeyinti, iglu kunye nokuveliswa kwecapsule.

 

Indlela:

Ukulungiswa kwe-ethyl benzoate ngokuqhelekileyo kwenziwa nge-esterification. Indlela ethile iquka ukusebenzisa i-benzoic acid kunye ne-ethanol njengezinto eziluhlaza, kwaye phambi kwe-catalyst ye-asidi, ukusabela kuqhutyelwa kwiqondo lokushisa elifanelekileyo kunye noxinzelelo lokufumana i-ethyl benzoate.

 

Ulwazi ngoKhuseleko:

I-Ethyl benzoate iyacaphukisa kwaye iyaguquguquka kwaye kufuneka ithintelwe ngokudibana ngqo nolusu kunye namehlo.

Ingqalelo kufuneka ihlawulwe ekuphuhliseni umoya ngexesha lenkqubo yonyango ukuphepha ukuphefumla umphunga okanye ukuvelisa imithombo yokutshisa.

Xa ugcina, gcina kude kwimithombo yobushushu kunye namadangatye avulekileyo, kwaye ugcine isikhongozelo sivalwe ngokuqinileyo.

Ukuba uphefumle umoya okanye ubanjwe ngempazamo, yiya kwindawo engena umoya ukuze ucoceke okanye ufune unyango kwangethuba.

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