Raman Spectrum Studies on Flash Point of Binary Liquid Mixture
Pages: 333-338
Year: Issue:  4
Journal: Chinese Journal of Light Scattering

Abstract: 本文以乙醇-甲酰胺,乙腈-甲酰胺,乙醇-环己酮,乙腈-环己酮四种混合溶液为研究对象,采用激光拉曼光谱对四种溶液体系的闪点行为进行讨论和研究.通过测定四种溶液体系的拉曼光谱和闪点,结合溶液拉曼光谱的特征峰强度比和拉曼位移的变化,探索四种溶液闪点的变化规律.试验结果表明,随着溶液浓度的增大,溶质的拉曼特征峰强线性增加,混合溶液的闪点降低.采用三次多项式分别对四种溶液体系的闪点与拉曼特征峰、溶液浓度的关...
