ABSTRACT:
A method of neutralizing the organic acidity in heavy gas oils to produce a neutralization number less than 1.0 whereby they are rendered suitable as lube oil feed stocks which comprises treating said heavy gas oils with a neutralizing amount of monoethanolamine to form an amine salt with the organic acids and then heating the thus-neutralized heavy gas oil at a temperature and for a time sufficient to convert the amine salts to amides.
