基于环保生产的理念,采用三氧化硫膜式磺化工艺代替传统浓硫酸工艺成功制备了 5 种不同SO3 结合量的硫酸化蓖麻油,解决了传统工艺中有废酸、废无机盐产生的问题.通过红外光谱和化学分析的手段证明了硫酸化蓖麻油的成功制备.研究了5 种不同SO3 结合量的硫酸化蓖麻油的性能,即表面张力、动态表面张力、乳化力、粒径以及皮革加脂应用,并以市售产品作对比.结果表明:与市售产品相比,采用SO3 工艺制备的硫酸化蓖麻油具有更优异的表面活性,γcmc最低为43.0 mN/m,cmc为9.3 mg/L,乳化力良好、粒径低于200 nm,且加脂性能优异.
Preparation of sulfated/sulfonated castor oil based on SO3 membrane sulfonation process and its properties
Based on the concept of environmentally friendly production,five kinds of sulfated castor oil with different organically combined sulfuric anhydride were successfully prepared by sulfur trioxide mem-brane sulfonation process instead of the traditional concentrated sulfuric acid process,which solved the problem of waste acid and waste inorganic salts in the traditional preparation process.The successful prep-aration of sulfated castor oil was demonstrated by means of infrared spectroscopy and chemical analysis.The properties of five sulfated castor oils with different organically combined sulfuric anhydride,namely surface tension,dynamic surface tension,emulsifying power,particle size and leather fatliquoring applica-tion,were studied and compared with commercially available products.The results showed that compared with the commercially available products,the sulfated castor oil prepared by SO3 process had better sur-face activity,with a minimum γcmc of 43.0 mN/m,a cmc of 9.3 mg/L,good emulsifying power,a particle size of less than 200 nm,and excellent fatliqouring performance.
