Production of hyperrbranched nonaolateate trimethylpropane for biolubricants basestock
Salma Samidin1, Nadia Salih2, Jumat Salimon3.
In this study, trioleate trimethylolpropane was successfully converted into hyperbranched nonaoleate trimethylolpropane via epoxidation with formic acid and hydrogen peroxide followed by the esterification via the oxirane ring opening reaction with oleic acids (OA). Sulphuric acid (SA) was found to be an effective catalyst compared to paratoluene sulfonic acid (PTSA) in the reaction of oxirane ring opening. High yield was obtained at 95%. Structure elucidation of the functional ester groups in hyperbranched product was confirmed by Fourier Transform Infrared (FTIR) and Nuclear Magnetic Resonance (NMR), 1H and 13C spectroscopy studies.
