13C3-三硬脂酸甘油酯的合成与表征
Synthesis and Characterization of 13C3-Tristearin
摘要
Abstract
A highly efficient synthesis of 13C3 labeled triglycerides of stearic acids from 13C3glycerol and stearic acids, by immobilized lipase-catalyzed in solvent-free medium was described. The structure of the product were characterized by fourier transform infrared spectrum (FT-IR), nuclear magnetic resonance (NMR), mass spectra (MS). The results showed that triglycerides of stearic acids contained three 13C atoms. The isotope abundance of 13C3-tristearin was more than 99％ and the yield was 80％ of 13C3-tristearin through calculation. Chemical purity (＞ 98％) was obtained by differential scanning calorimetry (DSC).关键词
