Lubricity additives for hydrocarbon fuels are provided according to formula I: wherein n is 1 or 0; each Q is independently selected from oxygen and sulfur; each R is independently selected from C8-C60 alkenyl groups which are substituted or unsubstituted; and L is a linking group comprising 0-20 carbons which may be substituted or unsubstituted and may optionally comprise catenary heteroatoms. Fuel mixtures comprising a hydrocarbon fuel; and a lubricity additive according to the present disclosure are also provided. Methods of making lubricity additives comprise reacting an alkenyl succinic anhydrides (ASA's) with certain bisamides or bisthioamides.

Synthetic lubricity additives for hydrocarbon fuels

Described herein are treated polymers comprising a polyacrylamide homopolymer or a copolymer thereof having at least 30 mol % acrylamide residue content and a weight average molecular weight in the range of 1&#xd7;10g/mol to 1&#xd7;10g/mol, and 0.1 wt % to 10 wt % of a C1-C6 alkyl ricinoleate based on the weight of the mixture of polymer and alkyl ricinoleate. The polymers are in powder form and include less than about 30 wt % water based on the powder weight. The treated polymer powders dissolve rapidly in water and develop very little or even no insoluble gel upon diluting with water, even when the water is produced water or connate. The treated polymer solutions are useful for in-the-field rapid dilution for applications such as papermaking, flocculation, beneficiation, wastewater treatment, and enhanced oil recovery.

High molecular weight polymer with low insoluble gel content

Water-in-oil lattices of water soluble polymers and methods of using the same are presented. The lattices are made, used, and stored having about 15 wt % to 70 wt % polymer solids and further include one or more alkyl ricinoleates. We have found that C1-C6 alkyl ricinoleates added to such lattices facilitate rapid and complete dilution to less than or equal to 1 wt % polymer solids in a continuous water phase. In particular under conditions wherein the water source used to invert the latex is provided at low temperature (&#x2212;10&#xb0; C. to 10&#xb0; C.), or includes a high level of total dissolved solids, or is both low temperature and high total dissolved solids.

Inversion agents for water-in-oil lattices and methods of use

2-substituted benzimidazoles and methods of preparing the same are disclosed. The compositions may include a compound or salt thereof, an acid, and a polar aprotic solvent. The compositions may be used to inhibit corrosion of a metal surface in contact with an aqueous system, and provide enhanced protection against corrosion of metals in the aqueous system.

One-pot homogeneous process for the large scale manufacture of 2-substituted benzimidazoles

A process for the manufacturing of a poly (arylether sulfone) polymer comprising reacting in a solvent mixture comprising a polar aprotic solvent and in the presence of an alkali metal carbonate, a monomer mixture which contains: at least one 1,4:3,6-dianhydrohexitol selected from the group consisting of isosorbide (1), isomannide (2) and isoidide (3); at least one dihaloaryl compound of formula (S): X&#x2014;Ar&#x2014;SO&#x2014;[Ar&#x2014;(T-Ar)&#x2014;SO]&#x2014;Ar&#x2014;X wherein n and m, equal to or different from each other, are independently zero or an integer of 1 to 5; X and X', equal to or different from each other, are halogens selected from F, Cl, Br, I; each of Ar, Ar, Arand Arequal to or different from each other and at each occurrence, is an aromatic moiety, T is a bond or a divalent group optionally comprising one or more than one heteroatom; optionally, at least one dihydroxyl compound different from the diol (AA); optionally, at least one dihaloaryl compound different from the dihalo (BB); and optionally, at least one hydroxyl-halo compound [hydro-halo (A&#x2032;B&#x2032;)]; being understood that the overall amount of halo-groups and hydroxyl-groups of the monomers of the monomer mixture is substantially equimolecular, so as to obtain a polymer (b-PAES), wherein the reaction is carried out at a total % monomer mixture concentration equal to or more 10% and less than 70% with respect to the combined weight of monomer mixture and solvent mixture.

Improved sparge compositions for reverse froth flotation separation and uses thereof, and improved methods of reverse froth flotation are described. Described are sparge compositions comprising collectors and beneficiating agents, the collectors comprising sulfonated fatty acids and/or salts thereof, and the beneficiating agents comprising a hydroxy fatty acid composition. The sparge compositions are suitably used in the reverse froth flotation to separate phosphate beneficiary from ores comprising phosphate and dolomite, calcite, silicate, and/or other gangues. The disclosed compositions and methods exhibit improved separation of phosphate from such ores.
