摘要

本研究调查了不同浓度（0.1、0.3 和 0.5) mM 的维生素 B7（生物素）对三种不同阳离子头基离子液体胶束化行为的影响，这三种离子液体分别是 N-甲基溴化吗啉[Mor1,12][Br]、N-十二烷基-N-甲基溴化吡咯烷[Pyrr1,12][Br]和 1-十二烷基-3-甲基溴化咪唑[C12mim][Br]。15、303.15、308.15 和 313.15）K 下，使用电导率和表面张力测量。所研究体系的评估 CMC 值用于获取有关离子液体在生物素存在下的胶体行为的信息。研究了不同的热力学参数。张力测定法用于确定界面特性。获得的参数用于研究胶束形成的不同类型的相互作用。研究这些相互作用的主要目的是进一步将这类混合物用于制药业、药物化学和生物工业。

Thermodynamic characteristics and aggregation behavior of surface active ionic liquids in presence of vitamin B7 (biotin)

This study investigated the influence of vitamin B7 (biotin) at different concentrations (0.1, 0.3 and 0.5) mM on the micellisation behaviour of three different ionic liquids with different cationic headgroups, namely N-methylmorpholinium bromide [Mor1,12][Br], N-dodecyl-N-methylpyrrolidinium bromide [Pyrr1,12][Br], and 1-dodecyl-3-methylimidazolium bromide [C12mim][Br], at four different temperatures (298.15, 303.15, 308.15, and 313.15) K using electrical conductivity and surface tension measurements. The evaluated CMC values for the studied system were used to obtain information about the colloidal behavior of the ionic liquids in the presence of biotin. The different thermodynamic parameters were studied. Tensiometry was used to determine the interfacial properties. The parameters obtained were used to study the different types of interactions for micelle formation. The main objective of studying these interactions is to further utilize this type of mixture in pharmaceutical industry, medicinal chemistry, and bio industry.
