Some phthalates are considered toxic and carcinogenic, which limits their use and demand for safer and more environmentally friendly plasticizers. The development of plasticizers produced from vegetable oil derivatives with a high degree of unsaturation is described, which allows the production of esters with a high epoxy content, guaranteeing excellent performance in terms of plasticization, high compatibility with polymeric materials such as polyvinyl chloride, polyesters, nitrocellulose, thereby avoiding migration when used in polymeric matrices. Fatty materials produced from linseed or tung oil have a high degree of unsaturation compared to vegetable oils such as soybean, corn, peanut, canola, sunflower; however, they are scarce and expensive when compared to them. we start Starting from common oils such as soybean and similar oils and separate the saturated part, generates materials with a high degree of unsaturation similar to fatty materials derived from linseed oil.

The present invention relates to the use of a fluid lubricant base comprising at least one biosourced and biodegradable compound having formula (I) in order to lubricate devices and/or machines, such as wind turbines, wherein said at least one compound having formula (I) corresponds to formula (I) in which R1, R2 and R3 are, independently, linear or branched saturated hydrocarbon groups comprising at least 16 carbon atoms, at least one group among R1, R2 and R3 comprises, on the hydrocarbon chain thereof, at least one ester group OCOR4, where R4 is a linear or branched alkyl radical comprising from 1 to 10 carbon atoms, preferably from 1 to 6 carbon atoms. The lubricant base has an acid number, in mg KOH/g measured according to the standard ISO 6618, which ranges from 0 to 0.5. The present invention further relates to a method for manufacturing the lubricant base as defined above and to the lubricant base thus obtained.

A method can include oxidizing hydrocarbons (and optionally oxygenates with oxygenation states less than carboxylic acids such as alcohols, aldehydes, etc.), separating the oxygenated hydrocarbons into saponifiable species and nonsaponifiable species, and treating the saponifiable species (e.g., heat treating, hydrogenation, etc. such as to reduce unsaturated bonds to saturated bonds, to convert oxygenates with greater degrees of oxygenation than monocarboxylic acids into monocarboxylic acids, etc.).

Subject matter of the present invention is a method for the production of fatty alcohols from alternative, renewable natural raw materials, the use of the fatty alcohols to produce surfactant intermediates or surfactants and a fatty alcohol composition. More specifically, the invention describes the transesterification of triglycerides and subsequent hydrogenation to fatty alcohols in an industrially desired carbon range, using insect oils, in particular oils from the black soldier fly larvae, as the feed stream or as part of the feed stream.
