A composition comprising alkyl esters, with a C-Calkyl group, and partial glycerides, with a free glycerol content of, at most, 2%, by weight, based on the weight of the composition, derived in an enzymatically-catalyzed reaction from saturated or unsaturated, straight or branched C-Cfatty acids of vegetable oils, and useful, inter alia, in biofuels, such as biodiesel, and as an additive for improving the lubricating performance of fuel compositions.

Compositions which can be used as biofuel

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&#x2014;NH, 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.
