Abstract: Additives may be used to decrease the viscosity of heavy residual hydrocarbons. The additives are prepared using a formulation comprising: a first component selected from the group consisting of (alkoxylated)-(di or tri)-alkyl phenol-aldehyde (amine) resins; ?-Olefin-maleic anhydride co-polymers and grafted polymers including half ester/amide and full ester/amide derivatives; and combinations thereof; and a second component which is a synergist and selected from the group consisting of polyamines, amidoamines, imidazolines, and combinations thereof.

Abstract: A composition for protecting wood from decay, mildew and sapstain comprises o-phenylphenol in combination with an alkoxylated amine, wherein the weight ratio of alkoxylated amine to o-phenylphenol ranges from 1:1 to 10:1. Organic or inorganic acids may be added to enhance solubility of the alkoxylated amines.
Abstract: Resins useful in methods of breaking oil-water emulsions. The resins obtained by reacting a compound of formula 1 with an aldehyde and alkoxylating, in any order:
wherein X is —NHR1; —COOH; or —CONHR2; and
is ortho—, meta— or para— to X and is a radical of —O—R3; —C(O)R4; —OC(O)R5; —NR6R7; wherein R1-R7 values are defined herein.

Abstract: This invention concerns a method for the treatment of waste-water. This method includes reacting a polyamine and a multifunctional epoxide in waste-water composition that initially is in the form of an emulsion to form a reaction product that causes the emulsion to break into a water phase and an oil phase. The oil phase and water phase may thereafter be physically separated from one another as by dissolved air flotation or chemical precipitation.
Abstract: Polymer compositions made by reacting a polyol with an aromatic hydrocarbon containing only a single reactive functionality have been discovered to be useful demulsifiers for crude oil compositions. The aromatic hydrocarbon should have at least one aryl group and only one functionality reactive with a hydroxyl. The polyol may optionally be crosslinked prior to reaction with the aromatic hydrocarbon, and the crosslinking agent may be a diepoxide.
