Abstract: Different observations on the waste fat of chicken with titanium dioxide was conducted at environmental situations to react to some probes concerning the transesterfication parameters such as lipids, proportion, reaction outcomes with thermal stability, type of periodic stages, reaction reversibility and finally glycerol usage. The tests were performed at various temperatures between 50°C-70°C and pressures till 35 MPa, while performing the tests were performed with chicken fat a little bit proposition (0.005 mg) of titanium dioxide is added for good performance, the outcome showed that the transesterfication procedure has produced biodiesel from economical lipid chicken skin oil in addition with titanium dioxide. It was also observed during the examination that thermal putrescence of chicken fat was not remarkable if it was warmed up to 300°C which resulted in the preheating of the feedstock up to the temperature mentioned during the initial stage of experimentation. Finally the utilisation of inexpensive chicken fat, linked with glycerol usage, has a prospective to improve biodesiel desirableness in the future.

Keywords: chicken fat; titanium dioxide; transesterification; biodiesel.
