硅碳自悬浮体的正负触变性

对硅碳白悬浮体做了系统工作。在含量较少的情况下呈牛顿型。含量达到一定程度后,产生三维结构,出现塑性体系。产生结构的固体含量与 PH 值有关。实验证明,在等电点(i,e,p.)附近结构最松驰。研究了水解聚丙烯酰胺(HPAM)对悬浮体的影响,发观在体系里的 HPAM 性能起主导作用,并破坏了原来硅碳白聚集体结构,呈絮凝体结构,并出现触变性。当高聚物在固体表面上一半时,具有最大动切力,即机械强度最高。同时产生最大触变性。聚丙烯酰胺的水解度较大时,体系出现了负触变性。

醇对正负离子表面活性剂双水相性质的影响

The effect of alcohol on the aqueous two-phase system properties of SDS/CTAB/H2O/Na2SO4 system was studied by the pseudo ternary phase diagram. The electrostatic forces (both attraction and repulsion) between cationic surfactant and anionic surfactant decreased because of the interaction of alcohol hydroxyl group and surfactant polar group. As a result, the phase area width of aqueous two-phase system increased. Long chain alcohol (more than five carbonatoms), which was in high concentration in the SDS/CTAB/H2O/Na2SO4) system, caused the anionic aqueous two-phase system area to vanish and the cationic aqueous two-phase system area to become wider. The CTAB rich phase turned from top phase to bottom phase.     

离子表面活性剂作为共模板合成性能优异的介孔钛硅分子筛

Ti-containing mesoporous silica materials(Ti-MSs) with isolated tetrahedrally coordinated Ti species have been widely applied in bulk molecular catalysis. Herein, Ti-MSs were synthesized using anionic surfactant SDS as the co-template. The SDS molecular assembled structures can interact with silica species through the interface hydrogen bonds leading to the formation of mesoporous silica structure with compact Ti-O bonds, lower hydrophilicity and low template cost. The influence of adding SDS as the co-template on the oxidation of styrene with aqueous H_2O_2 as the oxidant was investigated. Ti-MSs using SDS as the co-template showed better catalytic performance as compared with mesoporous titanium silicate synthesized with CTAB serving as the sole template. Moreover, the Ti-MSs synthesized at a Ti/Si ratio of 0.005 demonstrated an optimized performance for styrene oxidation with styrene conversion improved by 14.8%, benzaldehyde selectivity improved by 13.7% and styrene oxide selectivity improved by 9.2% when the reaction time was 6 h.
