樟脑磺酸钇的合成

Synthesis of Rare Metal Yttrium of Camphor Sulfonic Acid

研究了左旋樟脑磺酸钇和右旋樟脑磺酸钇的制备。实验以合成樟脑粉为原料,经过磺化反应、拆分、纯化分离等步骤得到手性樟脑磺酸,稀土金属氧化钇与手性樟脑磺酸反应合成了稀土金属樟脑磺酸钇,合成条件：樟脑磺酸质量浓度12%-15%,反应温度90℃,反应时间0.5-1 h,氧化钇过量50%。得到的产品稀土金属樟脑磺酸钇经红外光谱（IR）、XRD分析,证明与目标产物一致。

This paper studied the preparation of Yttrium of L- camphor sulfonic acid and Yttrium of D- camphor sulfonic acid. In this experiment,racemic camphor was uesd as the raw material,and through the sulfonation reaction,split,purification and separate,chiral camphor sulfonic acid was abtained,and it can react with Y2O3 to get yttrium of chiral Camphor sulfonic acid. The optimal synthesis conditions were： Camphor sulfonic acid concentration was 12%- 15%,reaction temperature was 90 ℃,reaction time was 0. 5- 1 h,Y2O3 excessed 50%. Tested by infrared spectroscopy（ IR） and XRD,it can be found that Yttrium of Rare Metal Camphor Sulfonic Acid are consistent with the standard compounds.
