Description
Summary:This work aimed to investigate the replacement of hexane by limonene in the extraction of wax from sugarcane peel, comparing the use of both solvents in terms of waxes yields, physicochemical properties, and composition, and presenting the difficulties faced in this replacement. The use of limonene produced extracts with similar melting points and higher content of fatty acids than the extracts obtained using hexane. Regarding the fatty alcohol percentage, while it decreased along the extraction time for the hexane extracts, due to the extraction of other chemical species, the opposite behavior occurred for limonene extracts. Although the purified limonene and hexane waxes showed similar physical properties, the use of limonene presented some drawbacks associated with the sample's residual limonene and the higher temperature required to boil it, which hinder its complete recovery and reuse. Thus, this work exemplifies the processing difficulties faced in replacing fossil solvents with renewables. [Display omitted] •Limonene evaluation as a greener solvent.•Waxes extracted by hexane and limonene presented similar physical properties.•The use of limonene provided higher contents of fatty acids.•The octacosanol content increased over time for the waxes extracted with limonene.•The limonene presents some drawbacks that hinder its complete recovery and reuse.
