LATENT HEAT-STORING SUBSTANCE, AQUEOUS SOLUTION, CLATHRATE HYDRATE AND ITS SLURRY, METHOD FOR ADJUSTING MELTING POINT OF CLATHRATE HYDRATE, METHOD FOR INCREASING LATENT HEAT STORAGE QUANTITY OF SLURRY OF CLATHRATE HYDRATE, AND METHOD FOR PRODUCING CLATHRATE HYDRATE OR ITS SLURRY

摘要

PROBLEM TO BE SOLVED: To provide a clathrate hydrate which remarkably improves the problem of metal corrosion and has a latent heat storage effect, to provide its slurry, to provide a latent heat-storing substance containing the clathrate hydrate and its slurry, to provide an aqueous solution capable of producing the clathrate hydrate and its slurry, to provide a method for adjusting the melting point of the clathrate hydrate, to provide a method for increasing the latent heat storage quantity of the slurry of the clathrate hydrate, and to provide a method for producing the clathrate hydrate and its slurry.;SOLUTION: This latent heat-storing substance is characterized by containing a pH-adjusting agent and a clathrate hydrate containing, as a guest compound, the salt of a cation with at least one of primary phosphate ion (H₂PO₄^-), secondary phosphate ion (HPO₄^2-) and tertiary phosphate ion (PO₄^3-).;COPYRIGHT: (C)2008,JPO&INPIT
