Paragraph 0025; 0026; 0027; 0028; 0029-0045; 0052, (2018/04/03)

The invention relates to a preparation method of 2-acrylamido-2-methylpropane sulfonic acid, and belongs to the field of organic synthesis and preparation. The preparation method comprises the steps of (1) adding acrylonitrile in a liquid-preparing kettle, cooling, and adding fuming sulfuric acid to obtain a mixed solution of acrylonitrile and sulfuric acid; (2) transferring partial mixed solution into a feed tank with a constant temperature for use, adding the residual mixed solution into a reaction kettle, adding an organic acid, heating, introducing isobutene, adding the standby mixed solution of acrylonitrile and sulfuric acid and controlling a temperature, a feed time and speed; (3) when isobutene is completely introduced, stirring while keeping the temperature, cooling, centrifuging or filtering to separate coarse crystals of a generated product and pumping a filtrate into a storage tank; (4) mixing the coarse crystals of the product with acrylonitrile under stirring, separating by centrifugation, drying in vacuum to obtain a product of 2-acrylamido-2-methylpropane sulfonic acid and pumping the filtrate into the storage tank; and (5) merging the filtrates, contacting the mixed filtrate with quicklime, and distilling to recycle acrylonitrile. The product provided by the invention has high purity and high polymerization activity and is liable to obtain a polymer with relatively high molecular weight.
