Abstract

PURPOSE: To prepare the title compound having and excellent color shade and stability, by adding specific amounts of a phenol compound and a boric compound to a crude fatty acid to deactivate the oxidation product and to convert the colored and smelly impurities to easily removable states, and then distilling the mixture.
CONSTITUTION: The title compounds are obtained by addition of 0.001W2wt% of a phenol compound and 0.01W2wt% of boric acid to natural fatty acids obtained from e.g. animal and plant fats and oils and fish oil or synthetic fatty acids obtained by the paraffin oxidation, oxo method, etc., followed by distillation. A phenol compound which can be used is e.g. tetrakis[methylene(3,5-di-t-butyl-4-hydroxyhydrocinnamate)]methane which shows an activity as an oxidation inhibitor. A boric acid compound which can be used is e.g. orthoboric acid which has an activity to convert, e.g. the chromophoric oxygen-containing impurities to an inert and easily removable heavy oil.
