【Abstract】 Objective To study the conditions of thickening AEO 9 solution. Methods AEO 9 and dodecylbenzene sulfonic acid of different weight ratio were mixed in the solutions. Acid was added to thicken the solutions, and their properties were tested. Results When weight ratio of dodecylbenzene sulfonic acid and AEO 9 was 3∶4 and the concentration of hydrochloric acid was 230-250 g/L, the solution was clear and transparent. Its viscosity was 146 mPa·s at 17 ℃ and its stability to temperature changes was good. Conclusion The AEO 9 solution can be thickened by adding acid. The solution made has suitable viscosity, clear transparency and good stability.更多还原
