Isiqinisekiso:COA, indawo yokunyibilika, iSpecificRotation [α]D20 Siza kuthumela nayiphi na idatha oyifunayo.Kodwa kwiimveliso ezenziwe ngokwezifiso, sithumela idatha entsha emva kokuba iphumile.
Ngokuqinisekileyo, unokubona idatha ngaphambili njengereferensi.

Zihlala zisetyenziselwa ukupakisha umgubo.Kuxhomekeke kwiimfuno zabathengi.Ke ngoko, sixelele ngemfuno yakho phambi kokupakisha ukuba unezicelo ezizodwa.
I-1kg ukuya kwi-25kg Ukupakisha kwangaphandle kunzima.Kwaye kunzima ukusika kunye nomonakalo.Inokukhusela iimveliso zakho ngokugqibeleleyo.
I-ester ngokuqhelekileyo ilulwelo olungenambala olungathathi hlangothi.I-ester eyenziwa ngumdyarho onamafutha kunye notywala obuhluthisiweyo inevumba lesiqhamo, elinokuchithwa emanzini, kwaye kunzima ukunyibilika emanzini.Enye i-ester flash point iphantsi kwaye ihlala itshisa.I-steam inokuthatyathwa ngumzila wokuphefumula, kwaye i-ester ye-liquid inokuthi ifakwe eluswini.Emva kokufunxa, inyibilika kwiplasma, kwaye ezinye zazo zikhutshwa ngemiphunga kunye nezintso.Emva kwe-hydrolysis ethile, jika ube yinkqubo eqhelekileyo ye-metabolic.Ukongeza kwiikhompawundi ezimbalwa ze-ester, uninzi lwazo zinetyhefu kakhulu kwaye zinetyhefu kakhulu, kwaye uninzi lwazo zinetyhefu kwiindidi ezinetyhefu eziphakathi, kwaye uninzi lwazo alunatyhefu.Kukho ii-esters ezingama-38 kumaqela ephunga leti.Ikakhulu: ① i-ester enamafutha: aveliswa butywala kunye namafutha, njenge-ethyl acetate, i-hexyl hexyate.② I-ester enevumba elimnandi: yenziwe ngotywala kunye ne-asidi enevumba elimnandi, njengeShun-3-hexylzyl.③ I-Circin esters: yenziwe ngotywala kunye ne-cyclocar, njenge-jasmone hyacxide.I-ester ngokuqhelekileyo ingathathi hlangothi, enokuthi ifakwe i-hydrolyzed kwaye ivelise utywala kunye ne-asidi.Amanani ekhabhoni ephantsi adla ngokuba lulwelo olunevumba elimnandi, kwaye amanani ekhabhoni aphezulu abulwelo kunye nezinto eziqinileyo ezinganyibilikiyo emanzini.
