Transesterification of canola oil on potassium-supported TiO2 catalysts
ABSTRACT The transesterification reaction of canola oil was studied on titania-supported catalysts with varying loadings of potassium. It was found that the most active catalysts fall in the range where the adsorption/ desorption of CO2 was the highest. Total conversion to methyl esters was achieved on a catalyst with 20% K-loading under air conditions and with no in situ pre-treatment before reaction.

Conference Proceeding: Poly(ethylene 2,6 naphthalene dicarboxylate) ageing under electrical discharges[show abstract] [hide abstract]
ABSTRACT: Poly(ethylene 2, 6 naphthalene dicarboxylate) (PEN) is studied to gain more knowledge in respect to its behaviour to corona discharge activity. After discharge treatment in air, the surface of bi-axially oriented films (12 μm) is optically analysed and unusual deposits are observed. ESCA, DMTA and dielectric loss tangent measurements allow the authors to propose a crosslinking process through radicular mechanisms to explain the evolution of the insulating materialProperties and Applications of Dielectric Materials, 1994., Proceedings of the 4th International Conference on; 08/1994
