ABSTRACT:
A composition containing: (a) 0.001% to 20% of at least one compound represented by formula (II),wherein R5is C1–C70difunctional alkyl or C6–C14difunctional aryl, and R3and R4independently are hydrogen, alkyl, heterocyclic, aryl or aralkyl groups; and (b) crude oil. In addition to dispersing asphaltenes, the composition of the present invention typically also increases demulsibility, reduces viscosity, reduces sediment formation, reduces surface fouling and reduces corrosion.
