α-羟基羧酸与硼酸的络合反应对其旋光的影响研究
Study on the Effect of the Complex Reaction between Boric Acid and Hydroxycarboxylic Acid on the Optical Rotation of Hydroxycarboxylic Acid
本论文从筛选和设计催化剂的角度,测量硼酸加入后α-羟基羧酸的旋光度的变化,分析络合反应产物种类与配合物构型变化的关系。采用多项式拟合,得到了旋光度与硼酸用量之间的函数。通过对拟合的旋光度函数进行微分求导,得到了旋光度变化率函数。结果表明,当形成配合物时,由于反应成环,电子可极化性增加,配合物的旋光度增加;当形成双配体的配合物时,形成了新的手性中心,但左旋体和右旋体的量相同,新形成的手性中心对旋光度增加贡献率为 0.即:对于旋光度为 0的α-羟基羧…查看全部>>
From the perspective of screening and designing catalysts,this paper measured the changes in the optical rotation of hydroxycarboxylic acids after the addition of boric acid,and analyzed the relationship between the types of complexation reaction products and the changes in complex configurations.The polynomial fitting was used to obtain the function between the rotation and the amount of boric acid used.The rate of change function of optical rotation is obt…查看全部>>
