The investigation of pyrolysis mechanism of heptakis[3- O -methyl-2,6-di- O -(methoxybenzyl)]-β-cyclodextrin by Py-GC and Py-GC/MS

摘要

The thermal stability and pyrolysis mechanism of heptakis[3-O-methyl-2,6-di-O-(methoxy-benzyl)]-β-cyclodextrin (MMBCD) were investigated by pyrolysis gas chromatography (Py-GC) and Py-GC/MS. MMBCD was stable up to 300℃. Several optical and positional isomers were baseline separated using MMBCD as the stationary phase.
