Investigation on the Influences of Reaction Parameters and Determination of Optimum Condition for the Synthesis of Sodium 2-Acrylamido-2-Methyl Propanesulfonate Using Experimental Design Approach

In this paper the synthesis of Sodium 2-Acrylamido-2-Methyl PropaneSulfonate (SAMPS) is studied and the influences of reaction parameters on the conversion are investigated using Taguchi experimental design approach. The results showed that among seven parameters including reaction temperature and time, aeration level and mixing rate in the reaction mixture, the addition sequence of initial materials, and finally the purity and the excess amount of sodium carbonate; just the last two factors as well as the reaction temperature have significant effects, respectively on the reaction extent, while the other factors are insignificant. The optimum conditions to attain the highest conversion are the higher purity and 25% excess amount of sodium carbonate, and 16°C for reaction temperature. The SAMPS product is also characterized by Furrier transform infrared (FT-IR), and hydrogen as well as carbon nuclear magnetic resonance (H-NMR and C-NMR). The morphology and the average particle size of the SAMPS product were also obtained as 20.09 mm (in the range of 1-60 mm) using Scanning Electron Microscopy (SEM).
