This article developed a two-step separating approach of cucurbit[n]uril compound, which was based on the different solubility of cucurbit[n]uril in water and hydrochloric acid. Several factors of separating were deliberated and the optimized separating conditions were fixed. The productivity of CB[5], CB[6], CB[7] and CB[8] is 78.9%, 92.0%, 88.0% and 75.0% respectively. The purity of cucurbit[n]uril is higher than 95% determined by NMR spectra. Especially for CB[5], the detected purity is up to 98%. The results proved the discussed method to be a simple and reliable CB[n] monomers separating process.
Key words: water and hydrochloric acid, separating, two-step approach, nuclear magnetic resonance, cucurbit[n]uril
