Sustainable process for the production of symmetrical dibasic acid ester-based thermal energy storage materials from lipids

Oleochemical-based long-chain diesters are potential organic phase change materials convenient for thermal energy storage. The development of efficient and green methods is an important requirement for the preparation of these environmentally friendly compounds, which also are finding wide industrial application. Thus, in the present work, a series of dibasic acid esters were synthesized through ionic liquid catalyzed scalable chemical esterification or transesterification reactions in a solvent-free medium. The starting compounds, dicarboxylic acids or their methyl esters and fatty alcohols or cholesterol, were reacted in the ratio of 1:2 respectively and the synthesized esters were characterized by FT-IR, 1 H NMR, and 13 C NMR.

Structural Effects on the Vaporization of High Molecular Weight Esters

To understand the effect of molecular weight and branching on the heats of vaporization (ΔHv) and their flow behavior, ΔHv and viscosity (η) were measured at different temperatures in the high molecular weight ester series: linear flexible di-n-alkyl sebacates and compact branched triglycerides with molecular weights ranging from 300 to 900. ΔHv0 values (ΔHv corrected to 298 K) have been obtained with experimental ΔHv and also computed according to the group additivity method; a smaller -CH2- group value of 3.8 kJ mol-1 compared to the normal value of 5.0 kJ mol-1 is found to give good agreement with the experimental data (within 2-5percent error).Both ester series have the same ΔHv0 irrespective of their molecular features, namely, shape, flexibility, and polarity, suggesting the coiling of the molecules during vaporization.The segmental motion of these ester series during their flow and its dependence on their molecular features unlike ΔHv0 are demonstrated by the correlation of the enthalpie of activation for viscous flow (ΔH*) and the ratio ΔEv/ΔH* = η (ΔEv is the energy of vaporization) with molecular weight.
