Banavali, R. M., and R. Mukkamala. "Compounds Containing Amide and Carboxyl Groups as Asphaltene Dispersants in Crude Oil." U.S. Patent 7,122,112, issued October 17, 2006.Mukkamala R, Banavali R M. Compounds containing amide and carboxyl groups as asphaltene dispersants in crude oil ...
A glycerol molecule contains three hydroxyl (–OH) groups. A fatty acid is a long chain of carbon atoms (from 4 to 24) with a carboxyl (–COOH) group at one end. The fatty acids in a fat may all be alike or they may all be different. They are bound to the glycerol molecule by...
In organic chemistry the concept of functional groups is useful as a basis for classification of large numbers of compounds according to their reactions. Some of the common functional groups are hydroxyl, present in alcohols and phenols; carboxyl, present in carboxylic acids; carbonyl, present in ...
Condensation reactions between N, N’-dimethyl-4-nitroaniline, and 2-nitrocarboxylbenzene or 2-nitro-4-sulfonicbenzene as the other partner yielded asymmetric azo products as the commercial methyl red and methyl orange, respectively, with selectivity up to 99%. In a reaction containing 1.0 ...
Some important structure-activity relationships of the derivative compound (7f) indicate the essence of the COOH group as R1 with other groups as R3 = R4 = R5 = OH. This activity can be enhanced in the near future research by introducing some new acid electron withdrawing groups (EWG) as ...
Chemical Properties of Three Functional Groups Alkane Commonly referred to as hydrocarbons, alkanes only contain single bonds linking each carbon and hydrogen atom together. In general, alkanes are reactive with other atoms and molecules. One chemical property of an alkane molecule is its ability to ...
attach the carboxyl group of the 5(6)-Carboxyfluorescein molecule and producing an amine-reactive O-acylisourea. For the fluorescent-IgG labelled silica nanoparticles this intermediate product reacted with the amino groups of the silica nanoparticles to yield an amide bond, releasing fluorescent-IgG ...
such as amino, or an acidic functional group, such as carboxyl, diastereomeric salts are formed with an appropriate optically-active acid or base, followed by resolution of the diastereomers thus formed by fractional crystallization or chromatographic means well known in the art, and subsequent recove...
these phenolic compounds are different than AHL considering their basic structures and their attached functional groups or side chain. The furanone also has lactone ring as like in AHL and is used as AHL analogue. But, this compound is different than the above mentioned phenolic compounds in view...
