Abstract:
A liquid clathrate that is formed from at least one liquid aromatic hydrocarbon and at least one tetrakis(aryl)borate salt, wherein each of the aryl groups is a fluorine-containing aryl group, each of which has bonded directly to an aromatic ring at least two fluorine atoms, or at least two perfluorohydrocarbyl groups, or at least one fluorine atom and at least one perfluorohydrocarbyl group, and wherein the cation is selected froma) a protic ammonium cation, wherein the protic ammonium cation has the formula [R3NH]âŠ•, in which each R is independently a nonaryl hydrocarbyl group containing up to about thirty carbon atoms, b) an onium cation, wherein the onium cation has the formula [ERn]âŠ•, wherein E is an element of any of Groups 15-17 of the Periodic Table, wherein each R is independently a hydrocarbyl group containing up to about thirty carbon atoms, and wherein n is equal to the valence of E plus one, and c) a triarylmethyl cation, wherein the triarylmethyl cation has three aryl groups bound to a central carbon atom, wherein the combination of said liquid aromatic hydrocarbon and said tetrakis(aryl)borate salt is effective to form a stable liquid clathrate.
