US Patent:

45899797, May 20, 1986

Filed:

Aug 22, 1985

Appl. No.:

6/768530

Inventors:

Sam Ferguson - Sugar Land TX
Darrell D. Reese - Beaumont TX

Assignee:

Nalco Chemical Company - Oak Brook IL

International Classification:

C10G 1700
C10G 4500

US Classification:

208263

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.

US Patent:

48270334, May 2, 1989

Filed:

May 18, 1987

Appl. No.:

7/051558

Inventors:

Sam Ferguson - Sugar Land TX
Darrell D. Reese - Richmond TX

Assignee:

Nalco Chemical Company - Naperville IL

International Classification:

C07C10319

US Classification:

564188

Abstract:

A naphthenic acid amide having the formula: ##STR1## where R is the hydrocarbon portion of a naphthenic acid, R. sub. 1 is H or Me X is O or NH, and n is a number having the value of 1-10. The method of producing such amides is also disclosed.

Sam Ferguson - Sugar Land TX
Darrell D. Reese - Richmond TX

Assignee:

Nalco Chemical Company - Naperville IL

International Classification:

C07C23318

US Classification:

564123

Abstract:

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, and n 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, and n 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.

Assignee:

Nalco Chemical Company - Naperville IL

International Classification:

C10G 1700

US Classification:

208263

Abstract:

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.
