Isingeniso

I-Ethyl benzoate) iyinhlanganisela yezinto eziphilayo eziwuketshezi olungenambala endaweni yokushisa. Okulandelayo ulwazi mayelana nezakhiwo, ukusetshenziswa, izindlela zokulungiselela nokuphepha kwe-ethyl benzoate:

 

Ikhwalithi:

Inephunga elimnandi futhi iyaguquguquka.

Incibilika kuzincibilikisi eziphilayo njenge-ethanol, i-ether, njll., ezingancibiliki emanzini.

 

Sebenzisa:

I-Ethyl benzoate isetshenziswa kakhulu njengesincibilikisi ezimbonini ezifana nopende, iglue kanye nokukhiqizwa kwama-capsule.

 

Indlela:

Ukulungiswa kwe-ethyl benzoate kuvame ukwenziwa nge-esterification. Indlela ethize ihlanganisa ukusebenzisa i-benzoic acid ne-ethanol njengezinto zokusetshenziswa, futhi lapho kukhona i-acid catalyst, ukusabela kwenziwa ezingeni lokushisa elifanele kanye nengcindezi yokuthola i-ethyl benzoate.

 

Ulwazi Lokuphepha:

I-Ethyl benzoate iyacasula futhi iyaguquguquka futhi kufanele igwenywe ngokuthintana ngqo nesikhumba namehlo.

Kufanele kuqashelwe ukuthi kungena umoya phakathi nenqubo yokwelapha ukuze kugwenywe ukuhogela isitimu noma ukukhiqiza imithombo yokuthungela.

Lapho ugcina, gcina kude nemithombo yokushisa namalangabi avulekile, futhi ugcine isiqukathi sivalwe ngokuqinile.

Uma uhogele umoya noma uthintwe ngephutha, hamba uye endaweni engenawo umoya ukuze uhlanzeke noma ufune usizo lwezempilo kusenesikhathi.

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
