摘要

本研究采用电导测定法,研究了药物-表面活性剂混合物(包括十四烷基三甲基溴化铵(TTAB)和盐酸丙嗪(PMZ))在水和单羟基有机化合物(乙醇(EtOH)、1-丙醇(1-PrOH)和2-丁醇(2-BuOH))的水溶液中的组装行为和理化参数。通过评估物理化学量(临界胶束浓度 (CMC)、反离子结合力 (β)、反离子结合力 (β) 和反离子结合力 (β)),对 TTAB 和 PMZ 之间的相互作用进行了表征、反离子结合(β)和热力学参数(标准吉布斯能({\Δ G}_{\varvec{m}}}^{{\varvec{o}}})、焓 (\({\Delta H}_{{\varvec{m}}}^{{\varvec{o}}}\)) 和熵 (\({\Delta S}_{{\varvec{m}}}^{{\varvec{o}}}\)).引入 PMZ 和 TTAB 表面活性剂后,CMC 值降低,β 值增加。TTAB 和 PMZ 混合物的 CMC 值随着温度的升高而增加。TTAB + PMZ 系统的胶束化是自发的,其值为\({-\Delta G}_{{\varvec{m}}}^{{\varvec{o}}}\)。观察到的\({\ΔH}_{{\varvec{m}}}^{0}\)和\({\ΔS}_{{\varvec{m}}}^{0}\)值表明,熵在 TTAB + PMZ 在q.介质中的组装过程中起主要作用,而在q.醇溶液中的结合则受焓和熵的共同作用。疏水作用是 TTAB 和 PMZ 在水介质中的主要作用力,而疏水作用和离子诱导偶极子作用则是在含水酒精介质中的可能作用力。通过适当的逻辑计算和描述了传递热力学和熵焓补偿参数。

Assessment of the assembly behaviour and physicochemical parameters for the tetradecyltrimethylammonium bromide and promazine hydrochloride mixture: Impact of monohydroxy organic compounds

This study investigates the assembly behaviour and physicochemical parameters of a drug-surfactant mixture comprising tetradecyltrimethylammonium bromide (TTAB) and promazine hydrochloride (PMZ) in water and aq. solutions of monohydroxy organic compounds (ethanol (EtOH), 1-propanol (1-PrOH), and 2-butanol (2-BuOH)) using conductometric method. The interaction between TTAB and PMZ has been characterized with the assessment of physicochemical quantities (critical micelle concentration (CMC), counter ion binding (β) and thermodynamic parameters (standard Gibbs energy (\({\Delta G}_{{\varvec{m}}}^{{\varvec{o}}}\)), enthalpy (\({\Delta H}_{{\varvec{m}}}^{{\varvec{o}}}\)), and entropy (\({\Delta S}_{{\varvec{m}}}^{{\varvec{o}}}\))). The introduction of PMZ with TTAB surfactant resulted in a reduction of the CMC value and an augmentation of the magnitude of β. The inclusion of alcohols causes the delaying creation of micelles above 5% w/w of all alcohols employed. The enhancement of CMC values was acquired with the increase of temperature for TTAB and PMZ mixture. The micellization of the TTAB + PMZ system was obtained as spontaneous with \({-\Delta G}_{{\varvec{m}}}^{{\varvec{o}}}\) values. The observed values of \({\Delta H}_{{\varvec{m}}}^{0}\) and \({\Delta S}_{{\varvec{m}}}^{0}\) indicate that, the entropy plays the main roles in the assembly of TTAB + PMZ in aq. media, while the association is governed by the joint contribution from enthalpy and entropy in aq. alcohol solutions. The hydrophobic interaction is the key forces of interaction between TTAB and PMZ in water medium, whereas hydrophobic and ion-induced dipole are the probable interaction in aq. alcohol media. The thermodynamic of transfer and entropy enthalpy compensation parameters are computed and described with proper logics.
