Abstract
Official abstract text for this publication.
Methods of purifying crude cyclopentadienyl magnesium compounds using a scavenging agent are provided. The purified cyclopentadienyl magnesium compounds have very low levels of metallic impurities.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of removing metallic impurities from a cyclopentadienyl magnesium compound comprising the steps of: providing a crude cyclopentadienyl magnesium compound; contacting the crude cyclopentadienyl magnesium compound with a scavenging agent comprising two or more tertiary amine groups to purify the cyclopentadienyl magnesium compound; and separating the purified cyclopentadienyl magnesium compound from the scavenging agent; wherein the scavenging agent is…
