Abstract
Structural Studies in Naturally Occurring Anthraquinones using Melting Points
S. B. Kalidhar
Abstract:
When a OH group of an anthrquinone changes to OMe : an increase in mp is indicative of chelated OH methylation; a decrease of mp up to 40°C also depicts chelated OH methylation ; a decrease of mp by 50°C or more hints nonchelated OH methylation.
Keywords:Anthraquinones; melting point; methylation
