Abstract
A process for the preparation of at least one ARN acid or salt thereof comprising: (I) allowing at least one ARN acid salt to form during the production of crude oil in the presence of water; (II) removing at least 5 wt % of the formed at least one ARN acid salt, e.g. from the oil water interface; and optionally (III) converting said salt into an acid.
Claims34
A process for preparing a food comprising:
- (I) allowing at least one ARN acid salt to form during the production of crude oil in the presence of water;
- (II) removing at least 5 wt % of the formed at least one ARN acid salt;
- (III) optionally converting said salt into an acid;
- (IV) optionally functionalizing the carboxyl groups of said ARN acid salt or said acid to change the polarity/charge on the molecule and form an ARN acid derivative;
- and
- (V) adding said ARN acid salt, said acid or said ARN acid derivative to a food.
A process for preparing a lubricant comprising:
- (I) allowing at least one ARN acid salt to form during the production of crude oil in the presence of water;
- (II) removing at least 5 wt % of the formed at least one ARN acid salt;
- (III) optionally converting said salt into an acid;
- and
- (IV) functionalizing the carboxyl groups of said ARN acid salt or said acid to form an ester or amide group.
A process for preparing a food comprising:
- (I) allowing at least one ARN acid salt to form during the production of crude oil in the presence of water;
- (II) removing at least 5 wt % of the formed at least one ARN acid salt;
- (III) if necessary, removing water or oil from the ARN acid salt;
- (IV) acidifying said ARN acid salt to form an ARN acid;
- (V) optionally cleaning said ARN acid;
- (VI) optionally functionalizing the carboxyl groups of said ARN acid to change the polarity/charge on the molecule and form an ARN acid derivative;
- and
- (V) adding said ARN acid or said ARN acid derivative to a food.

A process for preparing a food comprising
- (I) adding at least one metal ion to a crude oil at a pH of at least 5 so as to form an ARN acid salt;
- (II) separating at least a part of the formed ARN acid salt from the crude oil;
- (III) optionally converting said salt into an acid;
- (IV) optionally functionalizing the carboxyl groups of said ARN acid salt or said acid to change the polarity/charge on the molecule and form an ARN acid derivative;
- and
