AQUEOUS SOLUTION HAVING PROPERTY FOR PRODUCING CLATHRATE HYDRATE, CLATHRATE HYDRATE CONTAINING QUATERNARY AMMONIUM SALT AS GUEST AND SLURRY OF THE CLATHRATE HYDRATE AND, METHOD FOR PRODUCING CLATHRATE HYDRATE, METHOD FOR INCREASING RATE FOR PRODUCING OR GROWING CLATHRATE HYDRATE, METHOD FOR PREVENTING OR CONTROLLING SUPERCOOLING PHENOMENON ON PRODUCTION OR GROWTH OF CLATHRATE HYDRATE
PROBLEM TO BE SOLVED: To provide a technique for adding a specific additive to an aqueous solution of raw material to increase the heat-storing rate of a clathrate hydrate, and to provide a technique for controlling or preventing a supercooling phenomenon.;SOLUTION: This aqueous solution containing a quaternary ammonium salt used as the guest compound of a clathrate hydrate and having a property for being cooled to produce the clathrate hydrate is characterized by adding an alkali metal phosphate. The clathrate hydrate is characterized by using, as a guest compound, the quaternary ammonium salt produced by cooling an aqueous solution containing a quaternary ammonium salt and an alkali metal phosphate.;COPYRIGHT: (C)2008,JPO&INPIT
