Isingeniso

I-Isoamyl alcohol, eyaziwa nangokuthi isobutanol, inefomula yamakhemikhali u-C5H12O. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:

 

Ikhwalithi:

1. I-isoamyl alcohol iwuketshezi olungenambala olunephunga elikhethekile lewayini.

2. Inephuzu lokubilisa elingu-131-132 °C kanye nokuminyana okuhlobene okungu-0.809g/mLat 25 °C (okukhanyayo).

3. I-isoamyl alcohol iyancibilika emanzini nasezincibilikisini eziningi eziphilayo.

 

Sebenzisa:

1. I-isoamyl alcohol ivame ukusetshenziswa njenge-solvent futhi inezinhlobonhlobo zezinhlelo zokusebenza zokumboza, iziyinki, izinto zokunamathisela kanye nama-ejenti okuhlanza.

2. Utshwala be-isoamyl bungasetshenziswa futhi ukuze kuhlanganiswe ezinye izinhlanganisela ezifana nama-ether, ama-ester, nama-aldehydes nama-ketone.

 

Indlela:

1. Indlela evamile yokulungiselela i-isoamyl alcohol itholakala nge-acidic alcohololysis reaction ye-ethanol ne-isobutylene.

2. Enye indlela yokulungiselela itholakala nge-hydrogenation ye-isobutylene.

 

Ulwazi Lokuphepha:

1. I-isoamyl alcohol iwuketshezi oluvutha umlilo olungabangela umlilo lapho ivezwe emthonjeni wokuthungela.

2. Uma usebenzisa i-isoamyl alcohol, kuyadingeka ukugwema ukuhogela, ukuthintana nesikhumba noma ukungena emzimbeni ukuvimbela ukulimala empilweni.

3. Izinyathelo ezinhle zokungenisa umoya kufanele zithathwe lapho kusetshenziswa utshwala be-isoamyl ukuze kuqinisekiswe ukujikeleza komoya endlini.

4. Uma kuvuza, i-isoamyl alcohol kufanele ihlukaniswe ngokushesha, futhi ukuvuza kufanele kulahlwe kahle ukuze kugwenywe ukusabela kwezinye izinto.
