Abstract: Kraft lignins (KL) were obtained from pulping alfa grass (Stipa Tenacissima) by increasing black liquor pH using sulfuric acid at four different values (6, 4.5, 2.5 and 1.5). The obtained lignin was treated with acetosolv process and carefully characterized by different spectroscopic and analytical methods, namely: FTIR, UV and NMR spectroscopy
