TL;DR: In this article, the formation of the calcium diglyceroxide (CDG) on the surface of CaO supported on neutral Al 2 O 3 was established by 13 C NMR spectroscopy.
Abstract: Transesterification of soybean oil was carried out over calcium oxide supported on Al 2 O 3 as solid base catalysts. Solid base catalysts were synthesized by wet impregnation of CaO on acidic, basic and neutral Al 2 O 3 . Solid basic catalysts investigated in this study were characterized by BET surface area, XRD, FTIR, CO 2 -TPD and TG/DTA techniques. Formation of fatty acid methyl esters (FAME) in this study was influenced by the nature of the catalyst prepared on different Al 2 O 3 supports. CaO supported on neutral-Al 2 O 3 exhibited higher FAME yield and the activation energy was determined to be 30.7 kJ/mol. The formation of the calcium diglyceroxide (CDG), on the surface of CaO supported on neutral Al 2 O 3 was established by 13 C NMR spectroscopy. The catalytic system (with CaO + CDG) on neutral Al 2 O 3 showed higher activity in the transesterification of soybean oil. Among the catalysts studied the conversion of soybean oil to FAME formation was as follows: CaO/neutral-Al 2 O 3 > CaO/basic-Al 2 O 3 > CaO/acidic-Al 2 O 3 . The presence of CDG on neutral Al 2 O 3 probably contributes to the higher activity. To our knowledge, this is the first report on identifying the formation of CDG on neutral Al 2 O 3 during the production of biodiesel.

TL;DR: The authors found that tallow and hydrogenated tallow were less well absorbed than linseed oil, while oleic acid showed high absorbability, and the absorbability of mutton fat increased with age.
