See full text

The present invention relates to a composition and method for inhibiting the formation of naphthenate solids in a liquid hydrocarbon. The method includes contacting a composition including a rosin amine having a formula (I): or (II): where formula (AA): represents a single or double bond; R1, R2 and R5 each independently represent H, alkyl, alkenyl or an alkynyl group each having between one and ten carbon atoms, —(R3O)nR4 wherein R3 is an alkyl group having 1 to 3 carbon atoms and R4 is H, alkyl, alkenyl or an alkynyl group each having between one and ten carbon atoms; n is an integer between 5 and 50; X is a halide, sulphate, phosphate or acetate ion; and a demulsifier intermediate with the liquid hydrocarbon.
