APPLICATION AND PREPARATION OF 2-CYCLOPENTYLCYCLOPENTANONE PERFUME

Pure 2 cyclopentylcyclopentanone was synthesized from crude 2 cyclopentylidenecyclopentanone separated from nylon acid byproduct. The qualitative analysis and identification of 2 cyclopentylcyclopentanone was performed by EA, GCMS,IR, 1H NMR, 13 C NMR. The purity of 2 cyclopentylcyclopentanone is 99.9% by GC. LD 50 is 5 381.5 mg/kg (M) and 5 087.5 mg/kg (F). It presents the odour like spearmint and could be used as flaver and daily use perfume.
