PARAFFIN-BASED LATENT HEAT-STORING MATERIAL COMPOSITION AND USE AS LATENT HEAT STORING MATERIAL OF PARAFFIN-BASED COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a paraffin-based latent heat-storing material composition having a melting point near the melting point of n-nonadecane and a large latent heat of fusion almost equal to that of an even number normal paraffin.SOLUTION: There is provided a paraffin-based latent heat-storing material composition which substantially comprises n-eicosane, n-octadecane and/or n-nonadecane, contains 83 mass% or more of n-eicosane, 13 mass% or less of n-octadecane and 17 mass% or less of n-nonadecane and has a melting point lower than n-eicosane and a latent heat of fusion of 230 J/g or more.
