泰 山 学 院 本科毕业论文 所 在 学 院 化学与化工学院 专 业 名 称 化 学 申请学士学位所属学科 理 学 年 级 二〇一二级 学生姓名、学号 王 义 2012100065 指导教师姓名、职称 王 平 教授 完 成 日 期 二〇一二年五月 摘 要 醛、酮等具有活泼α-H的化合物（酸、酯、硝基化合物、氰基化合物、末端炔烃…）与甲醛、胺（一级胺、二级胺或氨）在乙醇溶液中回流，使酮的α-H被胺甲基取代。该反应也称为胺甲基化反应，所的产物成为曼尼希（Mannich）碱。 曼尼希碱（Mannich base）和和衍生物浓时具有强烈的粪臭味，扩散力强而持久；高度稀释的溶液有香味，可以作为香料使用。从而引起了人们对该类化合物的浓厚兴趣并进行了深入的研究。而衍生物中的NH结构有三阶光学非线性，已经成为光学领域的研究热点。 本实验以与丙酸反应,以钼酸铵为催化剂在石蜡浴并在搅拌条件下回流合成新的合物，在真空干燥箱内28oC恒定温度下对合物进行单晶培养，并对其进行。 曼尼希碱，三阶光学非线性，金属配合物ABSTRACT Aldehydes and ketones is lively and alpha H compounds (acid, esters, nitrocompounds, p-cyanic-benzyl compounds With formaldehyde, amine (level 1, level 2 amine or amine ammonia in ethanol solution), make the backflow testosterone alpha H was amine methyl replaced. This reaction is also called amine methylation, the product of the reaction was named Mannich alkali. Mannich base and 2-p-trifluoromethylaniline and derivatives thick with a strong odor of dung, diffusion of strong power and lasting; Highly diluted solution have fragrance, can be used as a flavoring. This arrised the people with the strong interest in this kind of compounds and studied. And 2-p-trifluoromethylaniline derivatives of NH possess third-order nonlinear optical properties, and has become a hot spot of research in the field of optics. In this experiments, we performed Mannich reaction using benzaldehyde, 2-p-trifluoromethylaniline and propionic acid as reactant and molybdate as catalyst and obtained a new compound. Using solvent evaporation method we grown the single crystals of the compound and determined its crystal structure by means of X-ray single crystal diffraction. Key words: Mannich base, third-order nonlinear optics, metal complexes目 录 1引 言--------------------------------------------------------------1 1.1 曼尼希反应的发展及曼尼希碱的应用---------------------------------1 1.2 曼尼希反应的操作选择----
