Abstract

In this research, For Vanillin preparation from lateral product of pulping factory, first,
lignin was extracted from kraft cooking liquors of softwood (pinus eldarica) and the
FT–IR spectrum of lignin was investigated and it was compared with standard. The
amount of extracted lignin was 27% based on oven dry weight of wood. Then vanillin
is prepared by oxidation of lignin under pressure. Finally the vanillin concentration in
product solution was analyzed with FT–IR and HPLC. The yield obtained from this
work was around 4.2% (wt vanillin / wt lignin).
