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 ]
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] [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 ...
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 .
The United States Federal Food, Drug, and Cosmetic Act (abbreviated as FFDCA, FDCA, or FD&C), is a set of laws passed by Congress in 1938 giving authority to the U.S. Food and Drug Administration (FDA) to oversee the safety of food, drugs, and cosmetics. A principal author of this law was Royal S. Copeland, a three-term U.S. Senator from New ...
Crotonic acid has 4 carbons, is included in croton oil, and is a trans-2-mono-unsaturated fatty acid.C 3 H 5 CO 2 H, IUPAC organization name (E)-but-2-enoic acid, trans-but-2-enoic acid, numerical representation 4:1, n-1, molecular weight 86.09, melting point 72–74 °C, boiling point 180–181 °C, specific gravity 1.027.
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 ...
