چکیده انگلیسی


• All organometallic complexes based on Sn(IV) are active in hydrolysis.
• Compared with industrial processes, these systems were effective at mild conditions.
• TG conversions to FA of ca. 80% were attained.

Tin(IV)-based compounds (mono-n-butyltin hydroxide oxide (a), di-n-butyl-oxo-stannane (b), di-n-butyl tin dilaurate (c) and tin oxide (d)) were used as catalysts in the hydrolysis of triacylglycerides (TGs). The effects of the nature and amount of the catalysts, the nature of the TGs, the temperature and reaction time were evaluated. Compared with the usual industrial processes, these systems showed excellent activities at mild temperatures and pressures, and low amounts of catalyst (ca. 0.3% w/woil). Fatty acid (FA) conversions of ca. 97% were obtained at 180 °C, 4 h at oil:water:catalyst a molar ratio of 1:24:0.01 and, using soybean oil.

Graphical abstractConversion of TGs to DGs, MGs and FAs (%) by hydrolysis in the presence of mono-n-butyltin hydroxide oxide (a) using soybean oil as determined by HPLC. Reaction conditions: oil:water:catalyst molar ratio = 1:6:0.01; temperature = 160 °C.Figure optionsDownload full-size imageDownload as PowerPoint slide
