Résumé:
The use of fossil fuels has resulted in environmental impacts that give rise to the development of
renewable energy. An excellent alternative is the search for energy sources and the production of
goods that do not depend on fossil raw materials. Just as there is a concern about the scarcity of oil
and the development of sustainable alternatives for energy production, there is currently another
problem that affects everyone: polluition. Although frying oil represents a tiny percentage of waste,
its environmental impact is very large on the ecossystem. The production of biolubricants from
vegetable oils is an alternative. One of the methodologies for the systhesis of biolubricants is
transesterification with ethanol, followed by epoxidation with peracetic acid of vegetable oil,
improving its lubricating characteristics. This work consists in the production of biolucants from
soybean oil for frying, coming from a university restaurant of the Federal University of Campina
Grande and comparing with the biolubricant from comercial soybean oil. The materials involved
in the process were characterized through their Chemical and physical-chemical properties.
Transesterification, with transformed the oil into biodiesel, provided a yield of 96% for the ethyl
biodiesel from fying oil and 98% for the ethyl biodiesel from comercial oil. Epoxidation, a reaction
that tranforms biodiesel into a biolubricant, provided a yield of 85% for the ethyl biolubricant in
the frying oil and 87,3% for the ethyl biolubricant in the comercial oil. The products obtained had
their properties adequate in comparison with the parameters established by the National Agency of
Petroleum, Natural Gas and Biofuels. In this way, the production of biodegradable lubricants can
significantly help to reduce the environmental impact of the use of fossil materials for the
production of lubricants, as well as the release of frying oil into the environmental.
