| titleOfInvention | Method of purification of o-phenanthroline |
| abstract | PURPOSE: A reaction mixture containing o-phenanthroline which has been produced through Skraup reaction and accompanied with a large amount of tarry byproducts is specifically treated to make the tarry byproducts insoluble and separate them thus permitting the isolation and purification of title compound useful as analytical reagent with industrial advantage. n COPYRIGHT: (C)1978,JPO&Japio |
