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] [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 ...
FDCA may refer to: 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
2,5-Furandicarboxaldehyde (FDC) is an organic compound with the molecular formula C 4 H 2 O(CHO) 2. It consists of a furan ring with aldehyde groups on the 2 and 5 position. It is therefore classified as a dialdehyde .
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 ...
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 ...
Trifluoroacetic acid is a widely employed acid, used for example in the synthesis of peptides.Its esters are useful in analytical chemistry. Longer-chain perfluoroalkyl carboxylic acids, e.g. with five to nine carbons, are useful fluorosurfactants and emulsifiers used in the production of polytetrafluoroethylene (Teflon) and related fluoropolymers.
Stock valuation is the method of calculating theoretical values of companies and their stocks.The main use of these methods is to predict future market prices, or more generally, potential market prices, and thus to profit from price movement – stocks that are judged undervalued (with respect to their theoretical value) are bought, while stocks that are judged overvalued are sold, in the ...
