Specification: 2m*3mm
Model: HH-Pino
Using aluminum silicate, molecular sieve, graphite, diatomaceous earth, silica gel, neutral alumina, and manganese dioxide as carriers, seven supported KMnO4 (1a~1g) were prepared, and their structures were characterized by XRD. Using 1 as the oxidant, the carbon-carbon double bond of verbenone completes the oxidative cleavage reaction, and an im
