2-17　Programing of average molecular structure analysis supporting program for lignin solubilized product

Abstract

An average molecular structure analysis supporting program was designed using Excel for lignin solubilized product. It covers mono-aromatic rings with 2-5 substituents including phenols and ethers using tertiary and quaternary aromatic carbon distributions, which obtained by elemental analysis, number averaged molecular weight, ¹³C-NMR techniques including dept and quat pulse sequences. For an average molecule having 5 aromatic ring cores, the program picked up the core structures within 3 minutes.
