Abstract
A family of organic compounds with chemical properties that make them suitable for use as phase change materials (PCMs), comprising, esters of dibasic acids are disclosed. These materials have high latent heats of fusion, low flammability, low miscibility with water, low cost, availability and a range of melting temperatures. The PCMs of the invention may be enclosed in a single, non-compartmentalized container with immiscible phase change material substances to moderate the temperature of a body between that of the melting temperatures of the PCMs.
