Aryl-alkyl Ether Linkages in Lignin

Abstract

Milled-wood ligninde bulunan aril-alkil eter bağlarının miktarını tayin etmek üzere, lignin numunesinin glikol-etanol karışımındaki çözeltisi 0.2 N hidroklorik asit ile asidolize tabi tutulmuştur. Asidoliz sırasında aril-alkil eter yapısındaki dimerlerde aril-alkil bağlarının kopması sonucu, serbest fenolik hidroksil grubu ihtiva eden p-sübstitü guayakol türevleri teşekkül edebileceğinden, serbest fenol gruplarının artışı, mevcut olabilecek a-karbonil gruplarının sodyum borhidrür ile indirgenmesinden sonra, 1-nitroso - 2-naftol renk reaksiyonu ile spektrofotometrik olarak tayin edilmiştir. Böylece “milled-spruce wood lignin” numunesinde asidoliz sırasında serbest fenolik hidroksil grubunun maksimum artma miktarı, her bir metoksil grubuna mukabil 0.30 mol olarak bulunmuştur. Dolayısı ile bu netice, ligninde her bir metoksil grubuna mukabil 0.30 mol aril-alkil eter yapısı olduğunu göstermiştir.
