摘要: 测定了正十六醇-正己烷烃溶液(0.01~0.20 mol·L~(-1))在不同浓度下的红外光谱, 并用付里叶自去卷积-曲线拟合法(Fourier Self-decon-volution and curve-fitting)对谱图进行了解析。结果将醇羟基峰归属为: (1)单体羟基峰(3646.6 m~(-1))、(2)链状缔合体末端游离羟基峰(3633.8 cm~(-1))、(3)环状二聚体羟基峰(3535.1 cm~(-1))、(4)链式二聚体缔合羟基峰(3474c m~(-1))和(5)链状多聚体组合羟基峰(3337 cm~(-1))五种类型, 并得出它们随浓度的分布规律。

Abstract: The IR spectra of n-C_(16)H_(33)OH/n-C_6H_(14)(n-hexadecanol/n-hexane) system in seven different alcohol concentrations (0.01-0.20 mol·L~(-1)) were measured and analysed by combined Fourier self-deconyolution and curve-fitting methods. The types of associa-tion in the system can be identified and their distribution can be evaluated.
