Title: Cellulose Ether From Chambal Wood


Saw dust of Chambal Wood (artocarpus chaplasha), a cellulosic waste, was successfully utilized for the preparation of sodium carboxymethylcellulose (Na-CMC), a water-soluble cellulose ether. San dust was analyzed for its moisture, ash, alcohol-benzene soluble substances, lignin and alpha-cellulose contents. Alpha-cellulose fraction was isolated and subsequently carboxymethylated to Na-CMC. Water-soluble product was purified and degree of substitution value was determined, Multistage carboxymethylation was perforrmed to get highly substituted Na-CMC.
