Comparison of bamboo lignophenols and alkaline lignins in hydroxymethylation conditions
In this study,bamboo lignophenols(LPs)and alkaline lignins(ALs)were respectively modified bymethylolation.The characterizations of bothunmodified and modified lignins were compared byusing 2D-HSQC NMR and 13C_NMR.It showed thatLPs have more active groups and alkaline lignins havemore condensation structures.The content of themethylol group in LPs was larger than that in ALs aftermethylolation.Most of the active positions which couldbe modified had been occupied during the pulpingprocess in the case of ALS.LPS was synthesizedthrough phase separation system.which showed highaccessibility on further modification.
