Abstract: The present invention contains methods, of making a cashew nutshell liquid alkoxylate sulfate surfactant by alkoxylation of a natural alkylphenol using propylene oxide (PO) and/or ethylene oxide (EO) followed by a sulfation reaction. The cashew nutshell liquid alkoxylate sulfate surfactant of the present invention is made by a facile and cost effective method. The natural hydrophobe surfactant of the present invention find uses in EOR applications where it is used for solubilization and mobilization of oil optionally containing asphaltene, wax, naphtenate, and for environmental cleanup. Further, the unsulfated version of the natural hydrophobe cardanol alkoxylate surfactant of the present invention can be used as ultra-high molecular weight non-ionic surfactant. Another advantage is that the composition is a renewable based surfactant that is non-toxic and biodegradable.

Abstract: The present invention contains methods, of making a cashew nutshell liquid alkoxylate carboxylate surfactant by alkoxylation of a natural alkylphenol using propylene oxide (PO) and/or ethylene oxide (EO) followed by a carboxymethylation reaction. The cashew nutshell liquid alkoxylate sulfate surfactant of the present invention is made by a facile and cost effective method. The natural hydrophobe surfactant of the present invention find uses in EOR applications where it is used for solubilization and mobilization of oil optionally containing asphaltene, wax, naphthenate, and for environmental cleanup. Another advantage is that the composition is a renewable based surfactant that is non-toxic and biodegradable.

Abstract: This invention relates a wax inhibitor for hydrocarbon oils comprising an esterified copolymer having repeating structural units derived from an esterified ethylenically unsaturated dicarboxylic acid and α-olefins having at least 18 carbon atoms, whereof at least 3 mol-% of the α-olefins have 30 or more carbon atoms, and wherein the ethylenically unsaturated dicarboxylic acid has been esterified with a mixture of alcohols comprising i) 70 to 97 mol-% of a saturated fatty alcohol having 18 to 24 carbon atoms and ii) 3 to 30 mol-% of an unsaturated alcohol having 16 to 24 carbon atoms.
