Abstract: A fluid composition is prepared by esterification of (a) at least one synthetic alcohol and (b) a mixture of fatty acids, including at least oleic and linoleic acids, and at least one of a mixture comprising a Miristic acid, Palmitoleic acid, Margarinic acid, Margaroleic acid, ?-Linoleic acid, Arachidic acid, Eicosenoic Behenic acid, and Erucic acid. The fatty acids can also include at least one of stearic acid and palmitic acid. The composition can be used as, or as part of, a quenching bath for a metal.

Abstract: Separate collection and conversion method and plant for the reuse of used oils and greases for energy purposes, which method provides one or more of the following steps: —producing and separating the waste from other substances or compounds, —collecting the waste—gathering/storing the waste in at least a collection and/or regeneration facility, —regenerating or treating the waste, —reusing the collected or regenerated or treated waste, an oil or a grease or a mixture containing at least a natural and/or synthetic ester-based oil and/or grease being considered as waste, which oil or grease or which mixture is the by-product or waste of industrial processes.

Abstract: Composition of one or more vegetable oils intended as triglycerides of natural origin with an oleic acid (C18:1) content less than 75%, preferably less than or equal to 74% which composition can be used for preparing dielectric fluids to be used in electrical transformers.
