Enzymatic Synthesis of Renewable 2,5- Bis(hydroxymethyl)furan-Based Polyesters
2,5-Bis(hydroxymethyl)furan (BHMF) is a highly valuable biobased rigid diol resembling aromatic monomers in polyester synthesis. In this work, BHMF is enzymatically polymerized with various diacid ethyl esters by Candida antarctica lipase b (CALB) via a two-stage, three-step method. A series of novel biobased furan polyesters are successfully produced, with number average molecular weights ( ...
متن کاملTandem synthesis of alternating polyesters from renewable resources
The vast majority of commodity materials are obtained from petrochemical feedstocks. These resources will plausibly be depleted within the next 100 years, and the peak in global oil production is estimated to occur within the next few decades. In this regard, biomass represents an abundant carbon-neutral renewable resource for the production of polymers. Here we report a new strategy, based on ...
متن کاملEnzyme-Catalyzed Synthesis of Unsaturated Aliphatic Polyesters Based on Green Monomers from Renewable Resources
Bio-based commercially available succinate, itaconate and 1,4-butanediol are enzymatically co-polymerized in solution via a two-stage method, using Candida antarctica Lipase B (CALB, in immobilized form as Novozyme® 435) as the biocatalyst. The chemical structures of the obtained products, poly(butylene succinate) (PBS) and poly(butylene succinate-co-itaconate) (PBSI), are confirmed by 1H- and ...
متن کاملThe Synthesis of Biodegradable Polycarbonates and Polyesters from Renewable Resources Using Highly Active (Porphyrin)Cr(III) Chloride Catalysts
A series of porphyrin metal(III) compounds of general formula LMX (where L = tetraphenylporphyrin, tetrakispentafluorophenylporphyrin and octaethylporphyrin, M = Al, Cr, Co, and X = Cl and OEt) has been synthesized and studied as catalysts for the ring opening polymerization of propylene oxide (PO) as well as copolymerization of PO with CO2 to produce polypropylene oxide (PPO), polypropylene ca...
متن کاملFour Carbon Oxychemicals from Renewable Resources
Butanol, butyric acid and butyraldehyde are important 4-carbon oxychemicals typically generated from petro-chemical sources. All have significant markets in the food industry either for direct use as flavorings or as chemical feedstocks for generating butyric acid and butyraldehyde derived flavour compounds. Strong consumer sentiment against the consumption of petro-chemical derived products yi...
