Influence of magnetic field and acid catalyst on the properties of products of epoxidation of methyl ester from the oil of Jatropha curcas L.
Abstract
The formulation and use of biolubricants represents an environmentally and economically viable alternative. The oil extracted from the Jatropha curcas L, has advantages with regard to minerals. But, to improve some of its properties, it is necessary to modify it chemically, such as the transesterification and epoxidation. The present study aims to assess the influence of the magnetic field and acid catalyst on the properties of products of epoxidation of methyl ester of Jatropha curcas L, through the determination of the properties chemical (iodine index, density, viscosity, acidity, oxidative stability index) of the products under different conditions. Favourable results with the use of the catalyst and magnetic treatment on the reaction of individually obtained, but the bigger influence occurs when combining the two effects.References
