Chemical characterization of the lignins of corn and soybean agricultural residues
Corn (CR) and soybean (SR) culture wastes were submitted to extraction with organic solvents for lignin isolation (LGS). The obtained lignin was chemically characterized, and based on studies of functional groups and microanalyses, it was possible to determine the minimum formula. LGS of CR has characteristics that resemble wood and of bamboo lignin, possessing a larger amount of methoxyl groups and vanillin.
