The general molecular formula for dicarboxylic acids can be written as HO 2 C−R−CO 2 H, where R can be aliphatic or aromatic. In general, dicarboxylic acids show similar chemical behavior and reactivity to monocarboxylic acids. Dicarboxylic acids are used in the preparation of copolymers such as polyamides and polyesters.
Dodecanedioic acid (DDDA) is a dicarboxylic acid with the formula (CH 2) 10 (CO 2 H) 2. A white solid, the compound finds a variety of applications ranging from polymers to materials. The unbranched compound is the most commonly encountered C12 dicarboxylic acid.
Diethyl oxomalonate is the diethyl ester of mesoxalic acid (ketomalonic acid), the simplest oxodicarboxylic acid and thus the first member (n = 0) of a homologous series HOOC–CO–(CH 2) n –COOH with the higher homologues oxalacetic acid (n = 1), α-ketoglutaric acid (n = 2) and α-ketoadipic acid (n = 3) (the latter a metabolite of the amino acid lysine).
Nhịp nhàng gái trai trẻ già, nắn cung đàn cùng hát lời ca, Mừng đất nước đổi mới chan hoà, Đời vui ấm no muôn nhà, tiếng ca cùng hoà. Khắp đất trời quê ta tiếng ca đậm đà. Các dân tộc Việt Nam cùng đón niềm vui, Mừng đất nước rộn rã tiếng cười.

General structure of 1,2-, 1,3-, and 1,4-dicarbonyls. In organic chemistry, a dicarbonyl is a molecule containing two carbonyl (C=O) groups.Although this term could refer to any organic compound containing two carbonyl groups, it is used more specifically to describe molecules in which both carbonyls are in close enough proximity that their reactivity is changed, such as 1,2-, 1,3-, and 1,4 ...
trans-Glutaconic acid is an organic compound with formula HO 2 CCH=CHCH 2 CO 2 H. This dicarboxylic acid exists as a colorless solid and is related to the saturated chemical glutaric acid, HO 2 CC(CH 2) 3 CO 2 H. Esters and salts of glutaconic acid are called glutaconates. Glutaconate bound to coenzyme A, glutaconyl-CoA, is an intermediate in ...
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]
