Cellulose Chemistry (Modification of cellulose by sulfuric acid and separately by maleic anhydride)Assuming cellulose with the chemical formula C6H10O5.......what happens if:
1) the cellulose is subjected to concentrated H2SO4 (sulfuruc acid) ---- how is the cellulose molecule/structure modified? and what are the reaction by-products.
2) similarly, what happens if cellulose is reacted with maleic anhydride C4H2O3? Again, how is the cellulose molecule/structure altered and what are the reaction by-products?
