| titleOfInvention | Polyamino bactericidal surfactant and preparation method and application thereof |
| abstract | The invention relates to a polyamino bactericidal surfactant, a preparation method and application thereof, wherein the method comprises the following steps: 1) mixing dipentaerythritol and caproyl chloride, and stirring and reacting for 2-4 hours at the temperature of 30-50 ℃ to obtain a viscous liquid intermediate I; 2) adding the viscous liquid intermediate I into a first solvent, adding powdery sodium hydroxide after the viscous liquid intermediate I is completely dissolved, stirring and reacting for 0.5-1 h at the temperature of 25-35 ℃, then adding 3-chloro-2-hydroxypropyl trimethyl ammonium chloride into the solution, heating to 70-90 ℃, reacting for 5-7 h, and carrying out suction filtration on the solution to obtain a solid product intermediate II; 3) and adding the solid product intermediate II into a second solvent, adding hexamethylene diisocyanate under stirring, heating to 40-50 ℃, reacting for 3-5 hours, and performing suction filtration and drying to obtain the polyamino bactericidal surfactant. The polyamino bactericidal surfactant solves the problem that in the process of oil field exploitation, injected water is used for breeding bacteria to corrode exploitation equipment, and further the petroleum yield and the oil gas quality are reduced. |
