Abstract: The present invention relates generally to amine curing agents compositions useful in formulation additives, compositions comprising systems, resin formulations, and the use of these compositions in methods of making objects by additive manufacturing using 3D printing methodologies.

Abstract: Well treatment fluids comprise well treatment additives comprising an ionic liquid. Method of treating a subterranean formation may comprise contacting the subterranean formation with the well treatment additive, wherein the well treatment additive comprises an ionic liquid comprising a cation and an anion having the following formula: [R1R2R3R4N]+[X]?, wherein R1, R2, R3, R4 are individually selected from the group consisting of an alkyl group, a hydroxyalkyl group, and a combination thereof provided that at least one of R1, R2, R3, R4 is the hydroxyalkyl group, and wherein the anion X? comprises at least one anion selected from the group consisting of F?, Cl?, Br?, I?, H2PO4?, HPO42?, PO43?, HSO4?, C7H7OSO3?, C7H7SO3?, SO42?, CH3SO3?, C2H5SO3?, CH3OSO3?, C2H5OSO3?, and combinations thereof.

Abstract: A variety of methods and well treatment fluids are disclosed, including, in one embodiment, a method of treating a subterranean formation, comprising contacting the subterranean formation with a well treatment additive, wherein the well treatment additive comprises an ionic liquid comprising a cation and an anion having the following formula: [R1R2R3R4N]+[X]?, wherein R1, R2, R3, R4 are individually selected from the group consisting of an alkyl group, a hydroxyalkyl group, and a combination thereof provided that at least one of R1, R2, R3, R4 is the hydroxyalkyl group, and wherein the anion X? comprises at least one anion selected from the group consisting of F?, Cl?, Br?, I?, H2PO4?, HPO42?, PO43?, HSO4?, C7H7OSO3?, C7H7SO3?, SO42?, CH3SO3?, C2H5OSO3?, CH3OSO3?, C2H5OSO3?, and combinations thereof. In one or more embodiments, a well treatment fluid comprises a base fluid and a well treatment additive comprising the ionic liquid.

Abstract: A variety of methods and compositions are disclosed, including, in one embodiment, a method of synthesizing an ionic liquid comprising a cation and an anion, comprising: reacting an alkyl hydroxyalkyl tertiary amine with an alkyl sulfate to form the ionic liquid having the following formula: [R1R2R3R4N]+[X]?, wherein R1, R2, R3, R4 are individually selected from the group consisting of an alkyl group, a hydroxyalkyl group, and a combination thereof provided that at least one of R1, R2, R3, R4 is the hydroxyalkyl group, and wherein the anion X? comprises at least one anion selected from the group consisting of F?, Cl?, Br?, I?, H2PO4?, HPO42? PO43?, HSO4?, C7H7OSO3?, C7H7SO3?, SO42?, C2H5SO4?, CH3SO3?, C2H5SO3?, CH3OSO3?, C2H5OSO3?, and combinations thereof.
