Coloured pigments from petroleum oxy acids for surface coatings
Abstract
A dewaxed and dearomatized petroleum fraction having a boiling range 180–250°C was oxidised by air at 140°C. under atmospheric pressure using cobalt or manganese naphthenate as catalyst. The oxynaphthenic acids were isolated from the oxidation product, purified and then neutralised to sodium salts.
