摘要 |
A novel crystalline material consisting of a enantiomeric pair of cyhalothrin isomers in the form of the racemic mixture and having greater insecticidal activity than cyhalothrin itself is described, together with a process for obtaining the enantiomeric pair of isomers by crystallization from concentrated cyhalothrin solutions in lower alkanols or liquid alkanes.
