| Overview | sodium allyloxyhydroxypropyl sulfonate is an anionic surfactant with a molecular formula of C6H11NaO5S and a molecular weight of 218.2, its structure contains three functional groups: carbon-carbon double bond (C = C), hydroxyl (-OH) and sulfonic acid group (-SO3), is a highly hydrophilic, polymerizable functional surface-active monomer. It can react with a monomer containing a carbon-carbon double bond (C = C) to prepare an aqueous resin having a high Hydroxyl value, Good wettability, and excellent adhesive strength, water resistance, and scrub resistance. |
| product features | in the polymerization, it is added as the bottom material of the kettle to play the role of emulsification and dispersion, and can participate in the polymerization, the resin system can form a good controllable molecular chain segment, the particle diameter distribution is wide, the foaming property is small, and the polymerization can be carried out in the low PH or high acidic monomer environment, good dispersion of pigments and fillers in the system; Excellent chemical and mechanical properties. |
| preparation | the preparation method of sodium allyloxyhydroxypropyl sulfonate is:(1) a certain amount of sodium hydroxide aqueous solution is added to the reaction kettle, the temperature is raised to 55~75 ℃, and the speed of the mixer is 150 ~ 300r/min;(2) sodium bisulfite aqueous solution and allyl glycidyl ether (AGE) are added dropwise at the same time with 30~90min, after the addition of heat preservation 60~120min;(3) with a certain amount of acid neutralization system of residual alkali, so that the pH value of the system at about 7, the product is allyl hydroxypropyl sulfonate; Wherein, the solid content of the system is 42±2%, the molar ratio of allyl glycidyl ether, sodium bisulfite and sodium hydroxide is 1 :( 1.05~1.2) (0.1-0.3), the remainder is deionized water; The acid may be one or more of concentrated hydrochloric acid, concentrated sulfuric acid or 2-acrylamido-2-methylpropanesulfonic acid (AMPS); this synthetic method is simple, safe, reliable and pollution-free. |
