摘要：NOVELTY - A palladium nanoparticle is prepared by adding acetic acid dissolved with 2,2'-dipyridylamine functionalized polyethylene glycol (PEG) (21 mg) to 2-mouth flask, adding palladium acetate (4.1 mg), stirring for 4 hours at room temperature, and coordinating; and blowing in hydrogen gas at room temperature, reducing, obtaining black-brown solution after 20 minutes, stopping blowing in hydrogen gas, adding 8 g of PEG to extract acetic acid, and obtaining palladium nanoparticle catalyst stabilized by 2,2'-dipyridylamine functionalized PEG. USE - Method for preparing palladium nanoparticle for aerobic oxidization reaction of alcohol (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for aerobic oxidization reaction of alcohol, comprising sequentially adding substrate (2.4 mmol) and palladium nanoparticle catalyst (0.018 mmol) to the 48 ml of high pressure kettle, and blowing mixed gases of carbon dioxide and oxygen gas in the high pressure kettle, heating to 80 degrees C, extracting substrate and product using supercritical carbon dioxide, and absorbing exhaust gas using cold trap filled with isopropanol at 0 degrees C.
