Methane → Cesium Chloride

Reaction Conditions

Reaction Steps

A two chamber process where in chamber 1 an aqueous solution of CsCl 0.2M (6 mL) and cucurbit[5]uril (500 mg) was prepared and natural gas passed through (20 mL/min) the solution for 1 to 5 minutes. The majority of methane in the natural gas was retained by the solution in chamber 1. In chamber 2 the exhaust of chamber 1 was passed through an aqueous solution of CsCl 0.2M (1.2 mL) and unsubstituted cucurbit[6]uril (100 mg). The solution of unsubstituted cucurbit[6]uril in chamber 2 was purged with nitrogen (at 20 mL/min) for 30 to 90 seconds to remove any residual methane and ethane (ethane 40 to 60% purity). The propane was then recovered from chamber 2 at 98 to 99% pure by either purging with nitrogen for 20 minutes or heating to 60 to 100° C.
