Njirimara physicochemical nke Alkyl Polyglycosides-omume nke oge
Usoro ọnụọgụ abụọ

Ọmarịcha arụmọrụ nke surfactants bụ n'ezie n'ihi mmetụta anụ ahụ na nke kemịkal pụrụ iche. Nke a na-emetụta n'otu aka na interface Njirimara na n'aka nke ọzọ omume na ngwọta, dị ka usoro omume. E jiri ya tụnyere mmanya ethoxylates (alkyl polyglycol ethers) na-aba ụba nke ukwuu, a na-amụchaghị ihe gbasara physicochemical nke alkyl glycosides ruo ugbu a. N'ime ọmụmụ ihe ndị a, a chọpụtala na alkyl polyglycosides nwere ihe ndị dị mkpa nke, n'ọnọdụ ụfọdụ, dị nnọọ iche na ndị ọzọ na-abụghị ionic surfactants. Achịkọtara nsonaazụ enwetara ugbu a dịka ndị a. Esemokwu dị ịrịba ama jikọtara na omume ethoxylates mmanya na-aba n'anya bụ ihe pụtara ìhè karịsịa.

E jiri ya tụnyere usoro ọmụmụ nke ethoxylates mmanya na-aba n'anya, ruo ugbu a ọ bụ naanị ọmụmụ ole na ole metụtara ihe dị iche iche dị ọcha ka emebere n'omume alkyl polyglycosides. Mgbe ị na-atụnyere nsonaazụ enwetara, ọ dị mkpa iburu n'uche na ọnụnọ nke akụkụ nke abụọ nwere mmetụta dị ukwuu na nkọwa nke eserese oge. Ka o sina dị, enwere ike ịme nchọpụta ndị bụ isi gbasara omume nke alkyl glycosides. A na-egosipụta omume nke usoro nke teknụzụ C8-10 Alkyl polyglycoside (C8-10 APG) na (Figure1). Na okpomọkụ n'elu 20 ℃, na C8-10 APG na-apụta ruo nnọọ elu nchegbu na isotropic frasi nke viscosity na-abawanye nke ukwuu. A na-etolite usoro lyotropic birefringent nke udidi nematic na gburugburu 95% site na ịdị arọ, nke na-agbanwe na gburugburu 98% site na ịdị arọ n'ime mpaghara mmiri mmiri gbara agba abụọ na alkyl polyglycoside siri ike. N'ebe okpomọkụ dị ntakịrị, a na-ahụkwa usoro kristal mmiri lamellar n'etiti 75 na 85% site n'ịdị arọ.
Maka n-octyl-β-D-glucoside dị mkpụmkpụ dị mkpụmkpụ, Nilsson et al nyochara eserese nke usoro ahụ n'ụzọ zuru ezu. na Sakya et al. A na-eji usoro ndị dị otú ahụ dị ka NMR na obere nkuku X-ray mgbasa (SAXS). Ọgụgụ 2 na-egosi usoro nke usoro. Na obere okpomọkụ, a na-ahụ akụkụ hexagonal, otu cubic na n'ikpeazụ a lamellar na ọdịnaya surfactant na-abawanye. Enwere ike ịkọwa ọdịiche dị na C8-10 alkyl polyglycoside Phase Eserese (Onyonyo 1) site na mbelata ogologo ogologo alkyl dị iche yana ọnụọgụ glucose dị iche na molecule (lee n'okpuru).
