Njikọ nke alkyl polyglycoside glycerol ethers

A na-eme njikọ nke alkyl polyglycoside glycerol ethers site na ụzọ atọ dị iche iche (Figure2, kama ngwakọta alkyl polyglycoside, naanị alkyl monoglycoside ka egosiri dị ka educt).Etherification nke alkyl polyglycoside na glycerol site na usoro A na-aga n'ihu n'okpuru ọnọdụ mmeghachi omume bụ isi.Mgbanaka oghere nke epoxide site na usoro B na-ewerekwa ọnọdụ n'ihu ihe ndị bụ isi.Nhọrọ ọzọ bụ mmeghachi omume na glycerol carbonate site na usoro C nke na-esonyere na mkpochapụ CO₂ na nke a na-eche na ọ na-esi na epoxide dị ka ọkwa etiti.

Ngwakọta mmeghachi omume na-ekpo ọkụ 200 ℃ n'ime oge nke awa 7 nke mmiri a na-emepụta na-aga n'ihu na-agbapụ iji wepụ nha nha dị ka o kwere mee n'akụkụ ngwaahịa.Dị ka a tụrụ anya ya, a na-emepụta alkyl polyglycoside di- na triglycerol ethers na mgbakwunye na ether monoglycerol.Mmeghachi omume ọzọ nke abụọ bụ nkwụsị nke glycerol iji mepụta oligoglycerol nke nwere ike imeghachi omume na alkyl polyglycoside n'otu ụzọ ahụ dị ka glycerol.Ụdị dị otú ahụ dị elu nke oligomers dị elu nwere ike ịbụ ihe na-achọsi ike n'ihi na ha na-emeziwanye hydrophilicity na ya mere dịka ọmụmaatụ mmiri solubility nke ngwaahịa.Mgbe etherification gasịrị, ngwaahịa ndị ahụ nwere ike ịgbaze na mmiri na ịcha ọcha n'ụzọ a maara, dịka ọmụmaatụ na hydrogen peroxide.

N'okpuru ọnọdụ mmeghachi omume ndị a, ogo nke etherification nke ngwaahịa na-adabere na ogologo alkyl nke alkyl polyglycoside eji.Ọnụọgụgụ3 na-egosi ọdịnaya pasentị nke mono-, di- na triglycerol ethers n'ime ngwakọta ngwaahịa crude maka ogologo yinye alkyl anọ dị iche iche.Mmeghachi omume nke C₁₂ alkyl polyglycoside na-enye nsonaazụ a na-ahụkarị.Dị ka chromatogram gas si kwuo, a na-emepụta mono-, di- na triglycerol ethers na nha nke 3: 2: 1.Ngụkọta ọdịnaya nke glycerol ethers dị gburugburu 35%.
