Intshayelelo
Amyl valerate. Oku kulandelayo yintshayelelo eneenkcukacha ye-amyl valerate:
Umgangatho:
- Imbonakalo: I-Amyl valerate lulwelo olungenambala ukuya kumthubi.
- Ivumba: Ivumba elineziqhamo.
- Ukunyibilika: ukunyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol, i-ether, ikloroform kunye nebenzene, kwaye zinyibilika kancinane kakhulu emanzini.
Sebenzisa:
- Ukusetyenziswa kwemizi-mveliso: I-Amyl valerate isetyenziswa ikakhulu njenge-solvent kwaye ingasetyenziselwa ukugquma, iipeyinti zokutshiza, ii-inki kunye nezicoci.
Indlela:
Ukulungiswa kwe-amyl valerate ngokuqhelekileyo kuqhutyelwa yi-esterification reaction, kwaye amanyathelo athile alandelayo:
I-asidi ye-Valeric iphendulwa ngotywala (n-amyl alcohol) phantsi kwesenzo se-catalyst efana ne-sulfuric acid okanye i-hydrochloric acid.
Ubushushu bokusabela buphakathi kwama-70-80°C.
Emva kokuba impendulo igqityiwe, i-amyl valerate ikhutshwe nge-distillation.
Ulwazi ngoKhuseleko:
- I-Amyl valerate lulwelo olunokutsha kwaye kufuneka lugcinwe kude nomlilo. Ukunyamekela kufuneka kuthathwe ukuphepha ukudibanisa nesikhumba kunye namehlo ngexesha lokuphatha.
-Nxiba izixhobo ezifanelekileyo zokuzikhusela ezinje ngeeglavu kunye nezibuko xa usebenzisa.
- Kwimeko yokuphefumla ngempazamo okanye ukungenwa ngengozi, funa unyango ngokukhawuleza.
