Nano-K2CO3: preparation, characterization and evaluation of reactive activities?
RSC Advances Pub Date: 2015-12-18 DOI: 10.1039/C5RA21597H
Abstract
A novel base, nano-K2CO3, was easily prepared by ultrafine wet milling. The surface properties and the reactive activities of nano-K2CO3 were characterized. It was found that such a base showed higher basicity than normal K2CO3 and could replace sodium (or potassium) alkoxide to carry out monoalkylation and oximation of active methylene compounds. The nano-K2CO3 could be regenarated and reused 10 times without loss of its reactive activity.
