摘要: Beech (Fagus sylvatica) wood samples were subjected to two-stage treatments following the philosophy of Milox process. By means incomplete, second-order, factorial designs, effects selected operational variables on composition and technical properties pulps assessed for optimization purposes. Under best conditions assayed, a pulp with 5.5% lignin, 86.3% cellulose 4.3% xylan was obtained at 46.6% yield. The showed good (kappa number = 25, SCAN viscosity higher than 1000 mL/g, R-10 test alkaline resistance 88.9%, R-18 91.8%), showing potentiality be used as feedstock dissolving production after TCF bleaching.
