Intshayelelo

I-Ethyl 3-hydroxybutyrate, eyaziwa ngokuba yi-butyl acetate, i-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa, kunye nolwazi lokhuseleko.

indalo:
I-Ethyl 3-hydroxybutyrate lulwelo olungenambala nevumba elimnandi. Inyibilika kwiintlobo ezininzi ze-solvents eziphilayo ezifana ne-ether, utywala, kunye ne-ketone. Inokuguquka okuphakathi.

Injongo:
I-Ethyl 3-hydroxybutyrate isetyenziswa ngokubanzi kwishishini njengenxalenye yeziqholo kunye ne-essence, enokubonelela ngencasa yeziqhamo kwiimveliso ezininzi, ezifana netshungama, iminti, iziselo kunye neemveliso zecuba.

Indlela yokuvelisa:
Ukulungiswa kwe-ethyl 3-hydroxybutyrate idla ngokufezekiswa ngokusabela kokutshintshiselana kwe-ester. Yenza i-asidi ye-butyric kunye ne-ethanol phantsi kweemeko ze-acidic ukuvelisa i-ethyl 3-hydroxybutyrate kunye namanzi. Emva kokuba impendulo igqityiwe, imveliso ihlanjululwa nge-distillation kunye nokulungiswa.

Ulwazi lokhuseleko:
I-Ethyl 3-hydroxybutyrate ngokuqhelekileyo ithathwa njengekhuselekile phantsi kweemeko eziqhelekileyo zokusetyenziswa. Njengemichiza, inokubangela ukucaphukisa ulusu, amehlo kunye nenkqubo yokuphefumla. Amanyathelo afanelekileyo okhuseleko kufuneka athathwe ngexesha lokudibana, njengokunxiba iiglavu zokhuselo, izibuko, kunye nemaski. Gwema ukuphefumla ngokuthe ngqo okanye ukungeniswa ngexesha lokusetyenziswa.
