Glyceryl Tributyrate

Figure 59. Theophile-Jules Pelouze (1807-1867). (Courtesy E. Berl.) Made many important contributions to organic and inorganic chemistry— ethereal salts, the first nitrile, borneol, glyceryl tributyrate, pyroxylin, improvements in the manufacture of plate glass. He nitrated paper in 1838 and was thus probably the first to prepare nitrocellulose. Reproduced from original in Kekule s portrait album.

Very recently, Montero and co-workers (369) have reported the pronounced structure sensitivity of MgO-catalyzed glyceryl tributyrate transesterification. In this study, size-controlled MgO nanoparticles were prepared by thermal treatment of Mg(OH)(OCH3). Controlled calcination was employed to control surface structure and the basicity was determined by the application of Auger spectroscopy and XPS. Figure 40 demonstrates the relationship between turnover frequency and snrface polarizability (which reflects surface basicity). It was found...

Reaction conditions temperature = 60°C, glyceryl tributyrate to methanol ratio = 1 12, and catalyst weight = 2 wt% versus the reactant mixture. Adapted from Ref. [148], Copyright 2010, Wiley. 

Mg-Co-Al-La layered double hydroxide was examined for the transesteri-fieation of canola with ethanol, fith 1 16 ratio of oil to ethanol and 2% of eatalyst and at a temperature of 200° C or 473K in a reaetor was observed to produce 97% of biodiesel in 4 h [69]. Caleined Li-Al, Mg-Al and Mg-Fe layered double hydroxides for the transesterifieation of both glyceryl tributyrate and soybean oil with methanol. With 1-3% of catalyst and oil to methanol ratio of 1 15 and at reflux temperature resulted in about 83% biodiesel yield [70].
