2,5-Furandicarboxylic acid (FDCA) is an organic chemical compound consisting of two carboxylic acid groups attached to a central furan ring. It was first reported as dehydromucic acid by Rudolph Fittig and Heinzelmann in 1876, who produced it via the action of concentrated hydrobromic acid upon mucic acid . [ 2 ]
2,5-furandicarboxylic acid, oxidized furan derivative and important building block for range of polymers Federal Food, Drug, and Cosmetic Act , set of laws passed by Congress giving authority to the U.S. Food and Drug Administration
This is a disproportionation reaction and produces a 1:1 ratio of 2-furoic acid and furfuryl alcohol (a 50% yield of each). [6] It remains economical because both products have commercial value. The bio-catalytic route involves the microorganism Nocardia corallina. This produces 2-furoic acid in higher yields: 98% from 2-furfuryl alcohol and 88 ...
The FDA recalled 60 doughnut products, totaling more than 2 million cases, for potential listeria contamination. The doughnuts were sold throughout the U.S. and Canada.
WASHINGTON (Reuters) -U.S. Secretary of State Marco Rubio will not attend an upcoming G20 meeting in South Africa, the top U.S. diplomat said on Wednesday, days after President Donald Trump ...
[2] [3] As an aromatic polyester from ethylene glycol it is a chemical analogue of polyethylene terephthalate (PET) and polyethylene naphthalate (PEN). PEF has been described in (patent) literature since 1951, [ 4 ] but has gained renewed attention since the US department of energy proclaimed its building block, FDCA, as a potential bio-based ...
The conservative-leaning Tax Foundation estimates that a 20% universal tariff on all imports into the U.S. would generate $4.5 trillion over 10 years before negative economic effects that would ...
Of these the most important is 2,5-furandicarboxylic acid, which has been proposed as a replacement for terephthalic acid in the production of polyesters. [20] [21] HMF can be converted to 2,5-dimethylfuran (DMF), a liquid that is a potential biofuel with a greater energy content than bioethanol. Hydrogenation of HMF gives 2,5-bis(hydroxymethyl ...
