For example, when the catalyst palladium is placed on barium sulfate and then treated with quinoline, the resulting catalyst reduces alkynes only as far as alkenes.

Quinoline is readily degradable by certain microorganisms, such as " Rhodococcus " species Strain Q1, which was isolated from soil and paper mill sludge.
43.
In addition, both oxygen and nitrogen heterocyclic hydrocarbons, such as parent and alkyl homologues of carbazole, quinoline, and pyridine, are present in many crude oils.
44.
Given the effectiveness of the reaction and the commercial availability of various Grieco partners, the Grieco three-component coupling is very useful for preparing quinoline libraries for drug discovery.
45.
Another large class of heterocycles are fused to benzene rings, which for pyridine, thiophene, pyrrole, and furan are quinoline, benzothiophene, indole, and benzofuran, respectively.
46.
The pK a for the quinoline nitrogen of chloroquine is 8.5, meaning it is about 10 % deprotonated at physiological pH as calculated by the Henderson-Hasselbalch equation.
47.
An example of such a 4-quinolone is " cipro " ( ciprofloxacin, image at right ), where the atoms of quinoline can be traced within this related structure.
48.
"' Quinoline "'is a heterocyclic aromatic organic compound with the chemical formula C 9 H 7 N . It is a colorless hygroscopic liquid with a strong odor.
49.
In addition to the impressive improvement in yield over the conventional procedure, the work up procedure was greatly simplified since quinoline, carbon dioxide, and ethanol were the only by-products formed.
50.
The formation of the quinoline product is influenced by the interaction of both R group on the diketone and using methoxy-substituted anilines leads to the formation of 2-CF 3-quinolines.
