ukupakisha kwangaphandle

Ibhokisi elukhuni inokukhusela iimveliso zakho ekuqhekekeni kwaye zibe manzi.

Usetyenziso

I-Ester yenziwe kwi-esterization reaction ye-asidi ye-inorganic okanye i-asidi ephilayo okanye utywala.Utywala okanye i-phenol okanye i-anhydride ene-acidic, i-alcohol kunye ne-ethylene, i-acidic yamahhala kunye ne-fatty nitrogen derivatives nayo inokuvelisa i-ester.I-hydrogen kwi-alpha-carbon kwii-molecule ze-ester ilahlekelwa utywala be-molecular kunye nenye i-molecular ester phantsi kweemeko ze-alkaline ukuvelisa i-β-keto ester, ebizwa ngokuba yi-ester contraction reaction.Ngokomzekelo, i-acetyl acetate yenziwe ukuvelisa i-acetyl ethyl acetate.Le mpendulo ibaluleke kakhulu kwi-organic synthesis.

Igama le-ester livela kwigama elihambelanayo le-carboxylic acid kunye notywala okanye i-phenol, njenge "asidi ethile kunye ne-ester ethile".Ii-esters zesangqa zibizwa ngokuba yilactone (lactone).Iimpawu zeekhemikhali ze-ester zifana ne-amyl niche anhydride, ejongene ne-hydrolysis, utywala kunye ne-ammonia reaction.I-ester yomgangatho ophantsi inevumba elimnandi kunye nolwelo oluguquguqukayo olungenambala, kwaye i-ester ephezulu iqinile.I-Estes zizinyibilikisi ezibalulekileyo kunye nemathiriyeli ekrwada yokwenziwa, kwaye ezinye ii-esters ziziyobisi ngokwazo.Ngokohlobo lwe-asidi, i-ester inokohlulwa ibe yi-ester ye-asidi ye-inorganic kunye ne-organic acid ester.I-Etate, i-ethyl acetate yi-ester enamafutha, i-acetate yi-ester enevumba elimnandi, kunye ne-namanonate yi-cyclic ester.

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.
