Izakhiwo Zomzimba Nezamakhemikhali Uketshezi oluguquguqukayo olungenambala. Inezithelo nephunga elimnandi. Iphuzu elincibilikayo -88 ℃, indawo yokubilisa 112~113 ℃. Incibilika kancane emanzini, ixubene nezinyibilikisi eziningi eziphilayo. Imikhiqizo yemvelo itholakala kuma-strawberry, uju, ama-molasses, ubhiya kanye ne-champagne.
Sebenzisa Isetshenziswa njengezinto zokusetshenziswa zokunambitheka kwe-flavour, ingasetshenziselwa ugwayi, imikhiqizo yamakhemikhali yansuku zonke noma eminye imikhiqizo, kodwa futhi i-solvent enhle kakhulu ye-organic.

Isingeniso

I-Ethyl isobutyrate. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: Uketshezi olungenambala.

- Iphunga: Inephunga elimnandi.

- Iyancibilika: i-ethanol, i-ether ne-ether, ayincibiliki emanzini.

- Ukuzinza: Ukuzinza, kodwa kungasha lapho kuvezwe emlilweni noma amazinga okushisa aphezulu.

 

Sebenzisa:

- Ukusetshenziswa kwezimboni: Kusetshenziswa njenge-solvent kuma-coatings, odayi, oyinki, nasezihlahleni.

 

Indlela:

Ukulungiswa kwe-ethyl isobutyrate kuvame ukuthatha ukusabela kwe-esterification ngezinyathelo ezilandelayo:

Engeza inani elithile le-catalyst (njenge-sulfuric acid noma i-hydrochloric acid).

Sabela ezingeni lokushisa elilungile isikhashana.

Ngemuva kokuthi ukusabela kuqediwe, i-ethyl isobutyrate ikhishwa nge-distillation nezinye izindlela.

 

Ulwazi Lokuphepha:

- I-Ethyl isobutyrate iyavutha futhi kufanele igcinwe kude nomlilo namazinga okushisa aphezulu.

- Gwema ukuhogela, ukuthinta isikhumba namehlo, futhi ugcine umoya omuhle lapho usebenzisa.

- Ungaxubani nama-oxidants aqinile nama-asidi, okungase kubangele ukusabela okuyingozi.

- Uma uhogela umoya noma uthintwa, phuma endaweni yesigameko ngokushesha uyofuna usizo lwezempilo.
