Abstract: The present invention relates to a process of decoloration of oil derivatives of plant origin. In particular, the present invention relates to a process of decoloration of oil derivatives of plant origin, comprising mixtures of butyl esters of medium-long chain fatty acids and oligomers thereof. The oil derivatives of plant origin thus obtained can be used for applications different from those in the traditional fields of tires, namely in those fields wherein the distinctive compositional characteristics of said derivatives are not sufficient if not also associated to suitable characteristics of color. Examples of such fields are, for example, those of the construction industry, paints, tanning industry.

Abstract: Phenol dissolved in an aqueous sulphatic stream discharged from a reactor in which cumene hydroperoxide is oxidized to phenol and acetone is recovered by extracting phenol present in said aqueous sulphatic stream containing phenol, Na.sub.2 SO.sub.4 and organic impurities, in a multi-step extractor with an organic solvent, thereby forming an extracted product organic phase and a refined aqueous product phase, the ratio of the extracted product phase to the refined product phase ranging from 0.1 to 1 v/v at a temperature ranging from 20.degree.-70.degree. C., and obtaining phenol by distillation or re-extraction of the recovered extracted product organic phase.
