THIOACIDOLYSIS MONOMERS DERIVED FROM LIGNINS: SYNTHESIS AND THEIR GC-MS RESPONSE FACTORS VS. INTERNAL STANDARDS

摘要：

In this work, a high yield synthetic approach to preparation of thioacidolysis monomers is presented. By using phenylglycerols, namely, guaiacyl and sinapyl and p-hydroxyphenyl as substrates, standard thioacidolysis reactions produce the corresponding monomers in almost quantitative yields. The monomers synthesized were characterized by NMR and GC-MS. With the synthesized phenylglycerols as models, GC-MS response factors of the thioacidolysis monomers vs. two internal standards, tetracosane (C24) and 4,4’-ethylenebisphenols (EBP) have been measured for the first time. The obtained results indicated that 4,4’-ethylenebisphenols is a better internal standard than the traditional tetracosane when GC-MS is used for quantitative measurement of thioacidolysis monomers derived from lignins.
