Symmetrical fatty dialkyl carbonates make a group of chemicals that has great potential for applications as phase change materials (PCMs). In this study, various parameters affecting synthesis of these carbonates are studied on laboratory scale, which includes: reactants ratio, reaction temperature and time, and the amount of catalyst used. Structures of the desired products are identified using FTIR and NMR spectroscopy. Differential scanning calorimetry (DSC) analysis is used for determining potential of the synthesized symmetrical fatty dialkyl carbonates as PCMs for energy-saving applications.

A series of organic carbonates derived from mid-, long-chain, and Guerbet alcohols were synthesized in good yields (69-80% isolated yields after purification by distillation or recrystallization) through a carbonate interchange reaction by heating the linear or Guerbet alcohols with diethyl carbonate in the presence of catalyst, n-dibutyltin oxide. The carbonates were isolated by Kuegelrohr distillation or recrystallization from acetone and characterized using FTIR, GC, 11H and 13C NMR spectroscopy, and GC-MS. El and positive Cl mass-spectral techniques were used to characterize the carbonates. Such materials are currently of commercial interest as lubricants and additives in various industrial applications.
