Malonate and furan based surfactants

Abstract

The invention is directed to a method for the preparation of a surfactant, said method comprising reacting a furanic compound according to formula (V), or a salt thereof, with a malonate according to formula (VI), or a salt thereof, to obtain a first furan-based surfactant precursor of formula (I) or a salt thereof, wherein R1 is H or CH2OX, wherein X is H or an aliphatic group; wherein R2, R3 and R4 are independently H or an aliphatic group; wherein the method further comprises one or more steps to convert the first furan-based surfactant precursor of formula (I), or a salt thereof, to a surfactant, which surfactant comprises a furan-moiety comprising a backbone structure of formula (VII), a hydrophilic moiety, preferably selected from the group consisting of sulfate, sulfonate, sulfinate, thiosulfate, sulfamidate, carboxylate, sarcosinate and taurate, phosphate, pyrophosphate, phosphonate, amines or ammonium, polyammonium, hydroxyammonium, pyridinium, picolinium, imidazolinium, benzimidazolinium, oxonium, sulfonium, phosphonium and non-ionic groups, and; a hydrophobic moiety comprising an aliphatic chain comprising at least 6 carbon atoms.
