Sulfonation of poly(p-phenylenediamine) polymer

Cogent Engineering, 2017
The sulfonation of poly(p-phenylenediamine) (P(pPD)) polymer was accomplished by oxidative copolymerization of p-phenylenediamine (pPD) with 2,5-diaminobenzenesulfonic acid (DABSA) and 2-aminobenzenesulfonic acid (2ABSA) monomers with 50/50 mol% ratios ...

Sulfonation of Expanded Polystyrene Post Consumption, Structural Analysis and Its Application in Chemical Enhanced Oil Recovery

Chemical Engineering Transactions, 2017
In this study, we selected two kinds of polystyrene (PS) from a whole solid waste mass, expanded (EPS) and extruded (XPS). These polymers were degassed in ethyl acetate (AcOEt) and sulfonated trough of two different methods.

Study on the Sulfonation of Straw Powder and The Application as High-effect Water Reducer [PDF]

, 2015
农作物秸秆中富含纤维素、半纤维素、木质素等光合作用产物，目前没有得到很好利用，是值得开发的可再生生物资源库。2015年我国的秸秆产生量将达到9亿多吨。焚烧秸秆不仅浪费资源，而且加重了雾霾等环境污染。因此，开发以秸秆等天然可再生资源为原料的减水剂等高附加值产品，对保护环境、推动生态产业的发展及减少化石类资源的消耗意义重大。 本论文利用本课题组开发的三氧化硫/1,2-二氯乙烷体系，开发了以不经分离和纯化的秸秆粉为原料，合成水溶性混合生物高分子硫酸单酯盐新工艺。成功获得了具有很好水溶性 ...
