HEAT-RETAINING SUBSTANCE Russian patent published in 2006 - IPC C09K5/06 

FIELD: heat-and-power engineering.

SUBSTANCE: invention is dealing with heat- retaining substances based on saturated hydrocarbons and provides heat carrier containing 88.0-90.5% n-heptadecane and 12.0-9.5% n-tricosane. Advantages of such composition compared to known one reside in that melting point of the substance is by 3.5-5.0°C below, which expands temperature application range, in particular enables use in heat accumulators to provide heat generation in thermoregulation and heat-supply systems at 17-18.5°C.

EFFECT: extended application area.
