Embodiment 1

[0038] Weigh 10g of citric acid and add it into a ground-mouth Erlenmeyer flask, then weigh 5g of dodecylamine into the Erlenmeyer flask, mix the two raw materials evenly, cover the bottle stopper, place it in an oven at 180°C, react for 6h, and take it out. Then cool to room temperature, add 200mL of deionized water to dissolve, and then add 2.5g of NaOH to adjust the pH to 7 to obtain dispersion A containing nano-surfactant.

Embodiment 2

[0040] Weigh 10g of sucrose into a ground-mouth Erlenmeyer flask, then weigh 1g of tetradecylamine into the Erlenmeyer flask, mix the two raw materials evenly, cover the bottle stopper, place it in an oven at 190°C, react for 2 hours, and take it out. Then cool to room temperature, add 100mL of deionized water to dissolve, and then add 1g of NaOH to adjust the pH to 6 to obtain dispersion B containing nanosurfactant.

Embodiment 3

[0042] Weigh 10g of glucose into a ground-mouth conical flask, then weigh 1g of hexadecylamine into the conical flask, mix the two raw materials evenly, cover the cork, place in an oven at 200°C, react for 4 hours, and take it out. Then cool to room temperature, add 150mL of deionized water to dissolve, and then add 1.5g of NaOH to adjust the pH to 9 to obtain dispersion C containing nano-surfactant.

Abstract

The invention discloses a nano surfactant and a preparation method thereof. The nano surfactant is prepared by reacting fatty amine with a compound A, wherein the compound A is a small molecular organic matter or an oligomer; and the molecular weights of the small molecular organic matters and the oligomers are 50-6000. The nano surfactant provided by the invention is synthesized from bottom to top by adopting a one-step method, not only has nanoscale, but also has interfacial activity, simplifies the reaction process and reduces the cost.

Description

technical field [0001] The application relates to a nanosurfactant and a preparation method thereof, belonging to the field of chemistry. Background technique [0002] Surfactant is a substance that can significantly change the interface state of a solution system. With fixed hydrophilic and lipophilic groups, it can be aligned on the surface of the solution. Nanomaterials have unique electrical, magnetic, optical, electrical, and thermal properties due to their small size effects, surface effects, and quantum effects. Nano-surfactant integrates the advantages of both. The nano-surfactant with large particle size plays the role of water plugging and profile control, while the nano-surfactant with small particle size continues to migrate and plays the role of washing oil. If the nanosurfactant oil displacement technology is applied to the oilfield chemical technology, the oilfield chemical application technology will be developed rapidly. [0003] The preparation methods o...
