Farnezila acetatoC17H28O2 estas kemia kombinaĵo, apartenanta al la funkcia grupo de la esteroj de la acetata acido kaj farnezila alkoholo. Farnezila acetato estas senkolora likvaĵo uzata kiel gustigagento kaj odorigagento en la nutrondustrio kaj en la fabrikado de kosmetikaĵoj. Kutime ĝi estiĝas per kondensiĝa reakcio aŭ per esterigo de Fischer-Speyer kun sulfata acido kiel katalizilo. Farnezila acetato estas malmulte solvebla en akvo, sed tute solvebla en alkoholo, duetila etero, kloroformo kaj plejmulto el la organikaj solvantoj. Farnezila acetato reakcias kun fortaj oksidigagentoj kaj fortaj bazoj.

Largest primates This is a list of large extant primate species (excluding humans) that can be ordered by average weight or height range. There is no fixed definition of a large primate, it is typically assessed empirically.[1] Primates exhibit the highest levels of sexual dimorphism amongst mammals,[2] therefore the maximum body dimensions included in this list generally refer to male specimens. Mandrills and baboons are monkeys; the rest of the species on this list are apes....
