“…These results indicate that THF accelerates the transesterification reaction and augments the conversion of triglycerides at lower temperature, requiring lesser concentration of catalyst. Similar results have been obtained in cottonseed oil [16], colza oil [17],rice bran oil [18] and chicken fat [19]. This makes THF as one of the most preferred green, clean and cheap adjunct for the biodiesel industry.…”

“…Some of these steps may also not be environment-friendly. Although, use of heterogeneous catalysts may have some advantages [4][5], their disadvantages are also many, like high alcohol to oil molar ratio (12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30), high temperature (120-200 0 C) and a very long reaction time of 3-8 hours [6]. Addition of co-solvents in the reaction medium is also an alternative approach which has been shown to enhance the reaction rates, as well as increasing the solubily and mass transfer between oil and methanol [7][8].…”

Base-catalyzed transesterification of waste cooking oil for the production of biodiesel was assisted by the addition of cosolventTetrahydrofuran (THF). In addition to lowering of reaction temperature and reduction in reaction time for transesterification, THF facilitated production of methyl ester in a single phase. THF-assisted base-catalyzed reaction was optimized for various parameters. Maximum biodiesel production(92.8%) was obtained with 4% THF; 0.6% sodium methoxide (catalyst), 6:1 methanol to oil ratio, 45 min reaction time, 50 0 C reaction temperature. Added to this, maximum glycerol recovery (18.62%) was obtained at 50 0 C using lower concentrations of THF(2%). Use of THF highlights even more economically viable and greener potential for biodiesel production as this co-solvent is non-toxic, unreactive and of biomass origin.
