Abstract

Ligninde serbest fenolik hidroksil gruplarının tayininde kullanılan l-nitroso-2- naftolün,guayakol halkasında hidroksil grubuna nazaran 4-yerinde karbonil grubu ihtiva eden lignin model bileşikleri ile renk reaksiyonu vermediği tesbit edildiğinden, lignin numunesi NaBH4 ile muamele edilerek karbonil grubunun indirgenmesi temin edilmiştir. Böylece indirgenmiş ve indirgenmemiş lignin numuneleri ile l-nitroso-2-naftol arasındaki reaksiyondan elde edilen rengin absorbansları arasındaki farktan ligninde mevcut 4-keto-guayakol grubu miktarı tayin edilmiştir.

Keywords
