The alkaline pH required for functionalization was provided by KOH (pKb = 0.5), as a weaker base than NaOH (pKb = 0.2) [35 ]. All chemicals were of reagent grade.
Ethanol c2h5oh
Ethanol (C2H5OH) is a clear, colorless, and flammable liquid. It is a commonly used organic solvent in various industries and laboratory settings. Ethanol has a distinctive odor and a burning taste. It is miscible with water and many other organic solvents.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
