Ukupakishwa kwangaphakathi

Zihlala zisetyenziselwa ukupakisha umgubo.Kuxhomekeke kwiimfuno zabathengi.Ke ngoko, sixelele ngemfuno yakho phambi kokupakisha ukuba unezicelo ezizodwa.

ukupakisha kwangaphandle

I-1kg ukuya kwi-25kg Ukupakisha kwangaphandle kunzima.Kwaye kunzima ukusika kunye nomonakalo.Inokukhusela iimveliso zakho ngokugqibeleleyo.

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.
