AQUEOUS SOLUTION HAVING PROPERTY FOR FORMING CLATHRATE HYDRATE, CLATHRATE HYDRATE CONTAINING QUATERNARY AMMONIUM SALT AS GUEST COMPOUND, SLURRY OF THE CLATHRATE HYDRATE, METHOD FOR PRODUCING CLATHRATE HYDRATE, METHOD FOR INCREASING RATE OF GENERATING OR GROWING CLATHRATE HYDRATE, AND METHOD FOR PREVENTING OR REDUCING SUPERCOOLING PHENOMENON CAUSED WHEN GENERATING OR GROWING CLATHRATE HYDRATE

摘要

PROBLEM TO BE SOLVED: To provide a technique for increasing a heat-reserving rate of a clathrate hydrate and a technique of preventing or reducing supercooling by adding a specific additive to a raw material aqueous solution.;SOLUTION: The aqueous solution having properties for generating a clathrate hydrate by being cooled, and containing a tetra(iso-pentyl)ammonium salt added thereto contains a quaternary ammonium salt except the tetra(iso-pentyl)ammonium salt being a guest compound of the clathrate hydrate. The clathrate hydrate using the quaternary ammonium salt as the guest compound is generated by cooling the aqueous solution containing the quaternary ammonium salt except the tetra(iso-pentyl)ammonium salt and the tetra(iso-pentyl)ammonium salt.;COPYRIGHT: (C)2009,JPO&INPIT
