Te whakahiatotanga o te Alkyl polyglycoside carbonates

I whakaritea nga warowaiha polyglycoside alkyl na roto i te whakawhitinga o nga alkyl monoglycosides me te diethyl carbonate (Whakaahua 4). I runga i te pai o te whakakotahitanga o nga tauhohenga, kua kitea he painga ki te whakamahi i te warowaikawa diethyl i te taikaha kia noho hei waahanga whakawhiti me te whakarewa. 2Mole-% o te 50% konutai wairewa wairewa ka tapiritia ki tenei ranunga me te whakaoho i te taha o te 120 ℃. I muri i nga haora 3 i raro i te reflux, ka tukuna te ranunga tauhohenga ki te whakamatao ki te 80 ℃ ka whakakorehia ki te 85% waikawa phosphoric. Ko te taikaha diethyl carbonate ka marewa ki te korehau. I raro i enei tikanga tauhohenga, he pai ake te whakamaarama i tetahi roopu hydroxyl. Te ōwehenga o te toenga whakaheke ki nga hua i te 1:2.5:1(monoglycoside: Monocarbonate:Polycarbonate).

I tua atu i te monocarbonate, ka hangaia nga hua me te ahua nui o te whakakapinga i roto i tenei tauhohenga. Ko te tohu o te taapiri warowaiha ka taea te whakahaere ma te mohio ki te whakahaere i te tauhohenga. Mo te C₁₂ monoglycoside, he tohatoha o te mono-, di- me te tricarbonate o te 7:3:1 ka riro mai i raro i nga tikanga tauhohenga i whakaahuatia ake nei (Whakaahua 5). Mena ka whakanuia te wa tauhohenga ki te 7haora, a ki te 2 mole o te waihano ka maturu i taua wa, ko te hua matua ko C₁₂ monoglycoside dicarbonate. Mena ka whakanuia ki te 10haora ka 3moles o te waihano ka whakakorehia, ko te hua matua ka riro ko te tricarbonate. Ko te tohu o te taapiri warowaiha me te toenga o te hydrophilic/lipophilic o te puhui polyglycoside alkyl ka taea te whakatika ma te rereke o te wa tauhohenga me te rōrahi distillate.
