NATURAL LOW TRANSITION TEMPERATURE MIXTURES (LTTMS) FOR BIOMASS DELIGNIFICATION
An effective dissociation of lignocellulosic biomass and their subsequent separation are needed for the production of high value products. Low transition temperature mixtures (LTTMs) tend to be the promising green solvents. In this study, low transition temperature mixtures (LTTMs) are prepared f...

description |
An effective dissociation of lignocellulosic biomass and their subsequent
separation are needed for the production of high value products. Low transition
temperature mixtures (LTTMs) tend to be the promising green solvents. In this study,
low transition temperature mixtures (LTTMs) are prepared from cheap commercially
available hydrogen bond acceptor (HBA) and L-malic acid as hydrogen bond donor
(HBD) in distinct molar ratio of feedstocks and proportion of water. The
physicochemical behaviours of the LTTMs synthesized in water such as hydrogen
bonding, thermal stability, glass transition temperature and biopolymers solubility are
studied andcompared. The representative peakof carboxylic acid group of malic acid
at 1710 cm" for the C=0 group turned broader and the peaks involved in the Hbonding
shifted and became broader within 2500-3600 cm"1 for the OH groups with
increased molar ratio of water during the preparation of LTTMs. Besides, the thermal
properties of the mixtures are not affected by the increased molar ratio of water. |
