Application | the molecular structure of 3-(cyclohexylamine)-2-hydroxy-1-propanesulfonic acid contains both hydrophilic sulfonate groups, also contains strong activity of hydroxyl, easy to take off, substitution and other reactions, so as an important functional material, can be used as organic chemical intermediates, the preparation of excellent anionic surfactant, modified starch, drilling fluid loss-reducing materials, polymer functional monomers and other chemicals. |
preparation | in a four-neck reaction flask were added 52 g (EDTA-2Na mmol) of sodium bisulfite, 52 g (20 mmol) of sodium sulfite, 1, 4.69g (5 mmol) and water 85. 5 mL(4 750 mmol), heat and stir to dissolve [take about 30% solution (solution A) for later use]; Control pH < 6. 5, 1 50 was added dropwise successively. 9g(0. 55mol) and solution A, drop, at 70 c (bath temperature) reaction to the end point (magenta solution does not fade). The reaction mixture was cooled to room temperature, crystallized, filtered under vacuum, and the filter cake was dried under vacuum at 105 ° C. To give a white solid. The synthetic procedure of 3-(cyclohexylamine)-2-hydroxy-1-propanesulfonic acid: sodium 2-hydroxy-3-chloropropanesulfonate and solvent tetrahydrofuran were added into cyclohexylamine at 0 ℃, stirring at room temperature for 1 hour, removing the solvent THF during reflux, stirring with hydrochloric acid water, extracting with ethyl acetate, and concentrating the organic layer to obtain white crystalline powder 3-(cyclohexylamine)-2-hydroxy-1-propanesulfonic acid, the yield was 93%. |
