What is the purpose of using 8-hydroxyquinoline for phenol equilibration?
The pheonol has been equilibrated with 3% NaCl and neutralized with Tris, and 0.1% 8-hydroxyquinoline has been added. The hydroxyquinoline is an antioxidant that reduces the formation of oxidation products of phenol such as quinones.
How do you make an 8-hydroxyquinoline solution?
Abstract: Substantially increased yields of pure-grade 8-hydroxyquinoline are obtained by gradual addition of a solution of o-nitrophenol in acrolein or in an allylidene acetal or diester, to an aqueous acid solution of o-aminophenol. 8-hydroxyquinoline is an article of commerce having known uses.
What are the uses of 8-hydroxyquinoline?
