FUEL ADDITIVE FORMULATION COMPRISING AT LEAST ONE COMPOSITION OBTAINED FROM HYDROXYMIDAZOLINE AND POLYAMINE AND USE THEREOF AS A FUEL ADDITIVE

摘要

Formulation of additives, in particular for fuels, comprising at least one component A and at least one component B said component A consisting of at least one polyglycol, soluble in said fuel, of number average molecular weight from 480 to 2100 and of general formula I: HO-R - (- OR-) xOR-OH in which each of the groups R independently represents a hydrocarbon group having from 2 to 6 carbon atoms and x represents the average degree of polymerization; and said component B consisting of at least one composition resulting, in a first step, from the reaction of at least one alkinyl- or polyalkinyl-succinic acid or anhydride on at least one 1- (2-hydroxyethyl) -imidazoline substituted with position 2 by an alkyl or alkinyl radical, linear or branched, having from 1 to 25 carbon atoms, in an imidazoline / succinic derivative molar ratio of 0.1: 1 to 0.9: 1 with elimination of at least 0, 15 mole of water per mole of imidazoline, then in a second step, of the reaction of the product resulting from the first step on at least one polyamine, comprising at least one terminal primary amino group, in an amount representing at least 0.1 mole by mole of succinic derivative used in the first step. /P P Use of these formulations as multifunctional additives in fuels based on hydrocarbons or on a mixture of hydrocarbons and at least one oxygenated compound chosen from the group formed by alcohols and ethers.
