USE OF POLYESTER AMIDES FOR THE STABILISATION OF ASPHALTENES IN CRUDE OIL |
摘要 |
<p>Processes for producing polyester amides, by reacting a polyisobutylene with a first reagent selected from the group consisting of at least monounsaturated acids having from 3 to 21 carbon atoms and derivatives thereof; and a second reagent selected from the group consisting of monoethanolamine and alkylamines of the general formula R-NH<SUB>2</SUB>, wherein R represents an alkyl group having from 1 to 4 carbon atoms; are described. The polyester amides thus produced and their uses in stabilizing asphaltenes in crude oil and crude oil derivatives are also described.</p> |
