Process for Pd-catalyzed hydroxycarbonylation of diisobutene: effect of solvent
A process for Pd-catalyzed hydroxycarbonylation of diisobutene in an acetic acid solvent in the presence of a ligand having the following structure: ##STR00001##
In contrast to reaction solvents such as formic acid or 3,5,5 hexanoic acid the conversion rates were improved and greater than 90% at a reaction temperature of 120 C. and CO pressure of 40 bar.
Ligand, ligand quantum dot, quantum dot layer and method for patterning the same
The present disclosure relates to a ligand for a quantum dot, a ligand quantum dot, a quantum dot layer and a method for patterning the same. The surface of the ligand quantum dot of the present disclosure is connected with the cleavage-type ligand including a first ligand unit A, a cleavage unit B, and an adhesion adjusting unit C. The method includes: providing a substrate; coating a mixture containing the ligand quantum dot on the substrate to form a quantum dot film; exposing a preset region of the quantum dot film to ultraviolet light, so that the cleavage unit B in the cleavage-type ligand undergoes a photolysis reaction, and a molecular segment containing the adhesion adjusting unit C and obtained after decomposition is detached from a surface of the quantum dot; and washing off an unexposed region of the quantum dot film with an organic solvent, followed by drying.
