    摘要: A method of producing naphthenic acid having the formula ##STR1## where R.sub.1 is H or Me,X is chosen, at each occurrence, from O or NH, andn is a small whole number of from 1-10,which comprises reacting an amine of the formula ##STR2## where R.sub.1 is H or Me,X is chosen, at each occurrence, from O or NH, andn is a small whole number of from 1-10,with a petroleum fraction containing naphthenic acids to form a salt and then heating the petroleum fraction containing the naphthenic acid-amine salt to a temperature of at least 25.degree. F. greater than the boiling point of water for a time sufficient to convert the amine salts to the amides and then recovering the thus produced amides.

    摘要: A method of neutralizing the organic acidity in petroleum and petroleum fractions 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 petroleum or petroleum fraction at a temperature and for a time sufficient to convert the amine salts to amides.
