2.3. Preparation of maleated lignocellulosic fibers
The modification of BF resulting from pulping and BMF resulting
from steam explosion was conducted in a round flask in the
presence of a solvent. The reaction procedure used for synthesizing
maleated lignocellulosic fiber and microfibrils was as follows:
250 ml of solvent (xylene) was placed in a 500 ml round flask
fixed with a condenser and stirred to 100 ◦C. After reaching this
temperature, 67–70 g of MA, 3 g of either BF, or BMF, and 1 g of
sodium hypophosphite monohydrate were placed in the flask. The
reaction was carried out for 2 h at 100 ◦C. After the reaction, the
mixture was filtered to isolate the reacted BF and BMF, subjected
to Soxhlet extraction with xylene for 24 h to remove the unreacted
anhydride, and oven dried at 70 ◦C for 24 h. The reaction product
thus obtained was characterized by FT-IR and scanning electron
microscopy (SEM).
