Abstract
The present invention provides novel clathrate compounds using tetrakisphenols as host. The clathrate compounds are obtained easily and efficiently by reacting tetrakisphenols represented by the general formula [I] as host and various organic compounds such as alcohol, ether, ester, ketone, heterocyclic compounds containing nitrogen, essential oil, perfume and the like as guest under the condition of solvent-free or diluted with solvent if required. ##STR1## wherein X represents (CH.sub.2)n, n represents 0-3, and R.sup.1 and R.sup.2 represents each independently hydrogen atom, a lower alkyl group, a pheny group optionally having substituents, a halogen atom or a lower alcoxy group. The clathrate compounds specified in the present invention are useful in the technological field of selective separation, chemical stabilization, conversion to non-volatility, powder processing and the like.
