Organotin Polyethers as Biomaterials
Organotin polyethers are easily synthesized employing interfacial polymerization systems involving the reaction of hydroxyl-containing Lewis bases and organotin halides. A wide variety of organotin-containing polymeric products have been synthesized including those derived from natural and synthetic polymers such as lignin, xylan, cellulose, dextran, and poly(vinyl alcohol). Others have been sy...
متن کاملMetallophthalocyanines as possible lignin peroxidase models.
Several metalloporphyrins, particularly highly chlorinated water soluble meso-tetraphenylporphyrins, have been shown to be good biomimetics of the lignin peroxidases which degrade lignin in vivo. Metal complexes of the water soluble phthalocyaninetetrasulfonic acid have been examined as catalysts for the oxidation of lignin since the phthalocyanines are readily available and inexpensive. The co...
متن کاملBackbone-thermoresponsive hyperbranched polyethers.
A new type of materials, the backbone-thermoresponsive hyperbranched polyether, was successfully synthesized by proton-transfer polymerization of 1,4-butanediol diglycidyl ether and various triols, and the lower critical solution temperature (LCST) values can be readily adjusted from 19.0 to 40.3 degrees C by changing the hydrophilic/hydrophobic balance of BDE and triols.
متن کاملLignin Depolymerisation under Supercritical Process Conditions for Aromatic Chemicals Production
Valorisation of lignin plays a key role in the further development of biorefinery processes for biofuels and the production of biobased materials from lignocellulosic biomass. Today’s increased demand for alternatives to fossil carbon based products, such as the production of transportation biofuels and bulk “green” chemicals, expands the interest and the need to create added value to the uncon...
متن کاملMathematical models of lignin biosynthesis
Background Lignin is a natural polymer that is interwoven with cellulose and hemicellulose within plant cell walls. Due to this molecular arrangement, lignin is a major contributor to the recalcitrance of plant materials with respect to the extraction of sugars and their fermentation into ethanol, butanol, and other potential bioenergy crops. The lignin biosynthetic pathway is similar, but not ...
