Suspensions comprising an organic base and at least one carrier fluid. The organic base comprises an amine group and at least one hydrophobic group attached to the amine group. The at least one hydrophobic group may be functionalized with one or more functional groups. Methods of extracting and obtaining a hydrocarbon material from a subterranean formation or bitumen using the suspension are disclosed.

1. A method of obtaining a hydrocarbon material, the method comprising: combining an organic base with a carrier fluid to form a suspension, the organic base selected from the group consisting of at least one of propylene diamine, butylene diamine, poly(vinylpyridine), polyvinyl imidazole, polyacryl
1. A method of obtaining a hydrocarbon material, the method comprising: combining an organic base with a carrier fluid to form a suspension, the organic base selected from the group consisting of at least one of propylene diamine, butylene diamine, poly(vinylpyridine), polyvinyl imidazole, polyacrylamide, poly(N-isopropylacrylamide), tripropylamine, dibutylamine, tributylamine, and combinations thereof, wherein the organic base reacts with an acid at a temperature greater than about 250° C.;contacting at least one of a subterranean formation comprising bitumen or a slurry comprising bitumen with the suspension to form an emulsion comprising at least one of a cationic surfactant and an anionic surfactant, the organic base, and the carrier fluid; andseparating a hydrocarbon material from the emulsion. 2. The method of claim 1, wherein the contacting at least one of a subterranean formation comprising bitumen or a slurry comprising bitumen with the suspension to form an emulsion comprises forming a cationic surfactant comprising a conjugate acid of the organic base. 3. The method of claim 1, wherein the separating a hydrocarbon material from the emulsion comprises altering a pH of the emulsion. 4. The method of claim 1, further comprising selecting the organic base to comprise tripropylamine, dibutylamine, or tributylamine. 5. The method of claim 1, further comprising selecting the organic base to comprise poly(vinylpyridine), polyvinyl imidazole, polyacrylamide, or poly(N-isopropylacrylamide). 6. The method of claim 1, further comprising selecting the organic base to comprise propylene diamine or butylene diamine. 7. A method of extracting a hydrocarbon material, the method comprising: mixing a compound comprising an organic base with a carrier fluid to form a mixture, wherein the compound reacts with an acid in a hydrocarbon-containing material at a temperature greater than about 250° C.;adding amine functionalized nanoparticles comprising one or more of silica, a metal, or a metal oxide to the mixture to form a flooding suspension including the amine functionalized nanoparticles and the compound;contacting the hydrocarbon-containing material with the flooding suspension and reacting the compound with acids present in the hydrocarbon-containing material to form an emulsion comprising surfactants where the compound contacts the hydrocarbon-containing material;transporting the emulsion; andremoving hydrocarbons from the emulsion. 8. The method of claim 7, wherein the mixing a compound comprising an organic base with a carrier fluid comprises heating the carrier fluid prior to mixing the compound with the carrier fluid. 9. The method of claim 7, wherein the mixing a compound comprising an organic base with a carrier fluid comprises forming the mixture to have between about 20 ppm and about 1,000 ppm of the compound. 10. The method of claim 7, further comprising selecting the compound to comprise an amine group coupled to one of an epoxy group or a halogen atom. 11. The method of claim 7, further comprising selecting the compound to comprise a polymer. 12. The method of claim 7, further comprising selecting the compound from the group consisting of ethanol amine, diethanol amine, triethanol amine, or a mixture thereof. 13. The method of claim 7, further comprising selecting the compound to comprise an amine coupled to a hydrophobic group selected from the group consisting of methanol, ethanol, propanol, butanol, pentanol, hexanol, heptanol, octanol, dodecanol, or octadecanol. 14. The method of claim 7, further comprising selecting the compound to comprise an amine group coupled to one of a nitrate group, a nitro group, or an azo group.
