IEEE Transactions on Dielectrics and Electrical Insulation, 2018
The paper presents research results of different properties of mixtures of the synthetic ester with mineral oil and synthetic ester with natural ester. For different concentrations of both mixtures, the following properties were investigated: flash point (open and closed cup), fire point (open cup), net calorific value, breakdown voltage, relative ...

Assessment of Flash and Fire point Measurements in Synthetic Ester under Retrofilling Scenarios
International Conference on Development and Learning, 2022Since being introduced 40 years ago, synthetic esters have become established as an alternative option to mineral oil in locations where enhanced fire protection measures are required.

PD Evolution and their Effect in Natural and Synthetic Ester Liquids
International Conference on Development and Learning, 2022The employment of natural and synthetic ester liquid as dielectrics in electrical equipment is increasing in the latest decades. They have higher fire and environmental performances if compared with the most used traditional mineral oils.

Melting points of synthetic wax esters
Lipids, 1969AbstractSaturated, monoenoic and dienoic wax esters, C26−C40, have been synthesized from even‐numbered fatty alcohols and acids. In homologous series of saturated esters, the increments of melting points follow a regular trend except for those esters which have an acid moiety two carbon atoms shorter than the alcohol moiety.
