A series of organic carbonates derived from mid‐, long‐chain, and Guerbet alcohols were synthesized in good yield (69–80% isolated yields after purification by distillation or recrystallization) though 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 Kügelrohr distillation or recrystallization from acetone and characterized using FTIR, GC, 1 H and 13 C 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.
