Modified alkaline electrolyte with 8-hydroxyquinoline and ZnO complex additives to improve Al-air battery

Journal of Power Sources, 2019
The behaviours of AA5052 alloy anode of the Al-air battery in alkaline electrolytes are investigated by the hydrogen gas evolution test and the electrochemical measurements. The combination of 8-hydroxyquinoline (8-HQ) and ZnO as the hybrid additives can

Tumor-targeted delivery of 8-hydroxyquinoline

International Journal of Radiation Oncology*Biology*Physics, 1991
RIF-1 mouse tumors express high levels of beta-glucuronidase activity relative to most normal tissues. The high activity can be exploited for targeting specific drugs preferentially to tumor tissues. In this study we examined the kinetics of 8-hydroxyquinoline (8-OHQ) accumulation in tumor and in several normal tissues resulting from the in vivo ...

Chloromethylation of 8-hydroxyquinoline

Analytica Chimica Acta, 1956
Abstract The reaction of formaldehyde on a hydrochloric acid solution of 8-hydroxyquinoline, in the presence of hydrochloric acid gas, gave a chloromethyl derivative which is probably 7-chloromethyl-8-hydroxyquinoline hydrochloride. This compound is readily converted into the 7-hydroxymethyl derivative in alkaline solution.
