Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels. 73-32-5, Name is H-Ile-OH, molecular formula is C6H13NO2. In an article, author is Zakaria, Noor Zawani,once mentioned of 73-32-5, SDS of cas: 73-32-5.
The quaternary-ammonium-salt-type amphiphilic compounds 3C(n)tris-s-Q X (star-type; carbon number between the central amino and ammonium groups s = 2, 3) and 3C(n)lin-3-Q X (linear-type; carbon number between the hydrophilic groups s = 3), where n represents the alkyl chain length (n = 8, 10, 12, 14) and X represents a counterion [hexafluorophosphate, trifluoromethanesulfonate (OTf), bis(fluorosulfonyl)amide (FSA), and bis(trifluoromethanesulfonyl)amide (NTf2)], were synthesized. Except for 3C(12)tris-3-Q OTf, these trimeric compounds presented melting points lower than 100 degrees C and therefore are defined as ionic liquids. Among them, 3C(n)tris-3-Q NTf2 (n = 8, 12, 14) and 3C(n)lin-3-Q NTf2 (n = 8, 10) presented melting points lower than 0 degrees C. The melting points of the amphiphilic trimeric ionic liquids (n = 8, 10), which were lower for the star- than for the linear-type compounds, were higher than those of the corresponding monomeric compounds but lower than those of the corresponding gemini samples. Moreover, the amphiphilic trimeric ionic liquids exhibited higher conductivities and lower viscosities than the corresponding gemini ionic liquids, while the star-type trimeric ionic liquids presented lower conductivities and higher viscosities than those of the linear-type compounds. The amphiphilic trimeric ionic liquids also readily adsorbed at the air/water interface and oriented themselves to form micelles in aqueous solution. This aggregation behavior was not observed in the monomeric and gemini ionic liquids.
