| titleOfInvention | A kind of oil field sewage sterilization and degreasing agent and its synthesis method and application |
| abstract | The invention belongs to the technical field of sewage treatment, and in particular relates to a sterilizing and degreasing agent for oil field sewage, a synthesis method and application. The synthetic method is as follows: adding tertiary amine, dihalobutene, isobutanol, and cupric chloride in a four-necked flask protected by nitrogen, and stirring the temperature for reflux reaction to obtain a crude intermediate product; rotary-evaporating the crude intermediate product to dryness , add water to heat up, stand for stratification, rotate the lower water phase to dryness, and recrystallize to obtain a pure intermediate; add the pure intermediate to a four-necked flask, add ethanol and sodium bisulfite, stir to heat up and reflux for reaction, The crude product is obtained; the crude product is rotary evaporated to dryness and recrystallized to obtain a sterilizing and degreasing agent. The sterilizing and degreasing agent has the characteristics of simple synthesis process, less dosage and low cost; when the concentration is 20mg/L, the sterilization rate can reach 100%; when the concentration is 50mg/L, the oil removal rate can reach more than 99%. |
